                               PROSPECTUS SUMMARY
   
  The following summary is qualified in its entirety by the detailed
information and financial statements and notes thereto appearing elsewhere in
this Prospectus. For purposes of this Prospectus, the "Company" refers to
Specialty Products & Insulation Co. and its consolidated subsidiary, unless the
context otherwise requires. Unless otherwise indicated, the information
contained in this Prospectus (i) gives effect to the spin-off of the Company
from its parent, Irex Corporation ("Irex"), through the pro rata distribution
of 100% of the capital stock of the Company to the shareholders of Irex (the
"Separation"), (ii) gives effect to the recapitalization of each share of the
Company's previously issued common stock into 291.3547 shares of Common Stock
and (iii) assumes no exercise of the Underwriters' over-allotment option in
connection with the Offering.     
 
                                  THE COMPANY
   
  Specialty Products & Insulation Co. is a leading national distributor and
fabricator of mechanical insulation, architectural/acoustical products and
specialty products to commercial and industrial markets. The Company also
offers customized fabrication, export and other value-added services related to
its core product lines. The Company operates through a national network of 52
distribution centers, including seven fabrication facilities, at strategically
chosen locations in 21 states. Through this network, the Company offers
approximately 25,000 stock keeping units ("SKUs") to more than 9,000 customers,
including specialty contractors, facility owners, general contractors, original
equipment manufacturers ("OEMs"), exporters and supply houses. The Company's
principal product categories include piping and equipment insulation as well as
acoustical ceilings and specialty wall panels for use in new construction,
maintenance, renovation and repair.These categories include the products of
more than 150 manufacturers including Armstrong World Industries, Owens
Corning, Johns Manville, Dow Chemical and Pittsburgh Corning. Since commencing
operations in the early 1980s, the Company has experienced significant growth
as a result of its ability to capitalize on industry changes including,
principally, the increased reliance on distributors by manufacturers and
customers. Net sales of the Company increased from $118.4 million in 1995 to
$158.5 million in 1997, and operating income grew from $4.1 million in 1995 to
$7.0 million in 1997. In the first three months of 1998, net sales and
operating income totalled $42.7 million and $1.4 million, respectively, as
compared to $36.3 million and $1.1 million, respectively, in the first three
months of 1997.     
 
  Significant changes in the Company's markets have resulted in the emergence
of an independent distribution channel. Independent distribution has reduced
duplicate functions performed by both manufacturers and customers, allowing
them to devote greater resources to their core competencies. Manufacturers have
been able to reduce logistical costs, lower marketing expenses and better
manage inventories by outsourcing the distribution function to independent
distributors. Customers have also been able to lower operating costs, reduce
their number of supply sources and gain high-quality, value-added services
through the utilization of independent distributors. This evolution has
produced markets which are highly fragmented and populated by many smaller
local and regional distributors. However, the Company believes the industry is
undergoing a significant trend toward consolidation as both manufacturers and
customers seek to enhance efficiencies and reduce costs while maintaining high
levels of product and service quality. The Company believes that large,
national distributors with significant purchasing power, integrated information
systems and relatively low infrastructure costs can offer greater value to
customers and will be well positioned to exceed market growth rates in this
industry.
 
  Two key components of the Company's growth strategy have been acquisitions
and openings of distribution and service centers ("distribution centers").
Historically, the Company grew as it solidified its presence in regional
markets. More recently, the Company has implemented a growth strategy that is
being executed on a national scale. Through targeted acquisitions and
distribution center openings, the Company pursues opportunities to expand its
presence in new geographic areas with strong growth characteristics. This
strategy enables the Company to further penetrate existing markets, broaden its
product and service capabilities and take advantage of current industry
dynamics. For the five-year period ended December 31, 1997, the Company
acquired 11 distribution operations, including three from affiliates, which
together contributed approximately $13.2 million, or 8.3%, of the Company's
1997 net sales. During the same period, the Company opened 10 distribution
centers, which together contributed approximately $12.3 million, or 7.8%, of
the Company's 1997
 
                                       3

net sales. Since January 1, 1998, the Company has completed one acquisition and
opened three distribution centers.     
 
  The Company is focused on its traditional strengths as a broadly based
national distributor and fabricator of mechanical insulation,
architectural/acoustical products, specialty products and value-added services.
The Company is committed to capitalizing on the expertise, knowledge and
experience it has developed in these core markets to increase market share and
profitability. In addition, the Company's operating strategy includes the
following key elements:
 
 .  Superior Customer Service. With distribution centers and sales forces in
   each area that it serves, the Company provides its customers with rapid
   delivery and localized service. The Company believes that providing a high
   level of customer service leads to long-term relationships with its
   customers.
 
 .  National Network of Distribution Centers. The Company believes its national
   distribution network enables the Company to attract customers that have
   multiple locations, participate with key vendors in the development of
   national marketing and sales strategies, achieve geographic diversification
   and facilitate best-practice benchmarking as well as innovation and
   knowledge-sharing within the Company.
 
 .  Strong Supplier Relationships. The Company believes its national presence,
   financial strength and partnering philosophy have enabled the Company to
   become the preferred distributor for many of its suppliers. The Company
   works with its suppliers to develop common expansion programs as well as
   customer-oriented product solutions.
   
 .   Low Cost of Operations. The Company believes that its volume of purchases
   and desirability as a vendor enable it to obtain purchase terms that are as
   favorable as those available to other large competitors. The Company is also
   able to realize advantages from the economies of large-scale operation in
   the areas of administrative processing, information systems, financing
   terms, technical expertise, inventory and working capital management.     
 
 .  Innovative and Committed Employees. Management believes the Company's
   corporate culture and values allow it to attract, develop and retain
   innovative and committed employees. The Company's senior management has an
   average of approximately 10 years' experience with the Company, and many of
   its sales and service staff have been working in the same markets for 10
   years or more.
 
  The Company believes that its operating strategy provides a foundation for
growth in each of the markets in which it participates. See "Business--Growth
Strategy." The Company's growth strategy includes the following key elements:
 
 .  Increase Sales of Existing and Accessory Products. Management believes the
   Company's strengths and operating strategies will lead to increased sales to
   its existing customer base. The Company believes acquisitions, the opening
   of new distribution centers and other strategic initiatives will generate
   additional sales of existing products to new customers.
 
 .  Open New Distribution Centers. The Company expects to continue to open new
   distribution centers as a result of new market opportunities, customer
   service requirements, supplier initiatives and strategic opportunities. As
   the Company continues to broaden its national distribution network, the
   Company believes that it will be able to capitalize on operating
   efficiencies and the benefits of large-scale operation.
 
 .  Continue Acquisitions. The Company is committed to continuing its strategy
   to acquire distribution businesses with strong market positions, supplier
   support or attractive customer bases. Acquisitions allow the Company to
   accelerate revenue growth, expand its geographical presence, add product
   lines and technical expertise and achieve greater operating efficiencies.
 
 .  Emphasize National Accounts. Management believes that the Company's national
   distribution network gives the Company a competitive advantage in securing
   national and multi-regional customers seeking to reduce vendors, outsource
   non-core operations, integrate supply and gain value-added services such as
   procurement and material management.
 
                                       4
<PAGE>
 
 
 .  Add Product Lines. The Company intends to leverage its core product and
   technical expertise to add product lines which are complementary to those
   currently offered. The Company believes that its existing national
   distribution infrastructure enables it to add new product lines without
   incurring significant additional cost.
   
  The Company's executive offices are located at 1097 Commercial Avenue, East
Petersburg, Pennsylvania 17520, and its telephone number is (717) 569-3900.
    
                               RECENT ACQUISITION
   
  On March 1, 1998, the Company acquired certain assets relating to mechanical
insulation distribution and fabrication operations of Extol of Texas, Inc. in
Houston and Corpus Christi, Texas ("Extol") for approximately $5.6 million in
cash. The acquisition was financed by borrowings from Irex. For the year ended
December 31, 1997, Extol generated sales of approximately $13.2 million. See
"Acquisition and Expansion Background." The Company has entered into a letter
of intent to purchase certain assets of a mechanical insulation fabricator with
fiscal year 1997 net sales of approximately $4.0 million.     
 
                             SEPARATION FROM PARENT
   
  Since commencing operations in 1982, the Company has been a wholly owned
subsidiary of Irex. Through its operating subsidiaries other than the Company,
Irex is primarily engaged in the business of specialty contracting throughout
the United States and Canada. In January 1998 Irex announced plans to effect
the Separation through a pro rata distribution of 100% of the capital stock of
the Company to the shareholders of Irex. The Separation will occur immediately
prior to consummation of the Offering, and the Offering is conditioned upon the
consummation of the Separation. Immediately following the Separation and the
Offering, all of the capital stock of the Company will be owned by the
shareholders of Irex who receive shares of Common Stock in the Separation and
by new shareholders who purchase Common Stock in the Offering. See "Separation
from Irex."     
 
  The decision to effect the Separation is based on a number of factors. The
Separation will provide both corporations with greater managerial, operational
and financial flexibility to focus on and respond to changing market conditions
in their respective business environments. The Company also believes that its
ability to pursue and finance acquisitions and other business opportunities
will be enhanced if the Company operates independently. Furthermore, financial
advisors have advised Irex and the Company that equity capital necessary to
meet the business needs of Irex and the Company can be most effectively raised
through an initial public offering of the stock of the Company following its
Separation from Irex, rather than through a stock offering by either Irex or
the Company while Irex continues to hold a substantial equity interest in the
Company. In addition, management believes the Separation will assist the
Company in serving certain customers. Through the specialty contracting
businesses operated by its other subsidiaries, Irex competes with customers
whose business is solicited by the Company, and the Company believes these
customers will be more likely to purchase products from the Company after it is
independent from Irex. The Separation will also enable the Company to provide
its management and employees with incentive compensation in the form of direct
and indirect equity ownership in the Company.
 
  In connection with the Separation, the Company will enter into several
agreements with Irex and its subsidiaries setting forth the terms and
conditions of the Separation and governing certain interim and longer-term
relationships between the companies. See "Separation from Irex--Agreements with
Irex."

                                 RISK FACTORS
 
  In evaluating an investment in the Common Stock offered hereby, prospective
investors should carefully consider the following risk factors as well as the
other information set forth elsewhere in this Prospectus.
 
LACK OF INDEPENDENT OPERATING HISTORY
 
  Concurrent with the Offering, the Company will separate from Irex pursuant
to the Separation. Prior to the Separation, the Company operated as a wholly
owned subsidiary of Irex, historically relied on Irex for various financial,
administrative and managerial services necessary for its operations and
maintained a minimal executive, financial and administrative staff. After the
Separation, the Company will maintain its own lines of credit and banking
relationships and perform its own financial, administrative and managerial
functions without the benefit of such services, and Irex will have no
obligation to provide assistance to the Company except pursuant to certain
agreements as described in "Separation from Irex--Agreements with Irex." While
management believes that the Separation will have a positive impact on the
Company, the Company may encounter financial, administrative, managerial or
other difficulties as a result of its lack of independent operating history or
the discontinuance of its reliance on the financial and other services of
Irex. No assurance can be given that the Company, as an independent entity,
will achieve operating results comparable to those prior to the Separation.
See "Separation from Irex."
 
LIMITATIONS ON ABILITY TO RAISE EQUITY CAPITAL AND POTENTIAL DEPENDENCE ON
DEBT FINANCING
 
  In order to preserve the tax-free status of the Separation, the Company's
future ability to issue Common Stock may be limited under federal income tax
laws for a period of two years following consummation of the Separation. The
Company's limited ability to issue capital stock during such period (including
its ability to issue Common Stock in connection with acquisitions) may require
the Company to rely on other financing sources, such as bank credit facilities
or debt offerings. Although the Company believes it can obtain financing
necessary to maintain its acquisition and growth program, reliance on such
alternative financing sources could adversely affect the Company's ability to
continue its acquisition program, create significant debt service obligations
and create other risks for the Company and its shareholders. No assurance can
be given that the Company will be able to obtain the capital it will need to
meet its operating needs and finance its acquisition program. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources" and "Business--Growth Strategy."
 
RISKS ASSOCIATED WITH FUTURE ACQUISITIONS; ABILITY TO MANAGE GROWTH
 
  The Company's growth strategy contemplates further acquisitions of
distribution and related businesses. The Company's future success is
dependent, in part, upon its ability to identify, finance and acquire suitable
businesses on favorable terms and then to integrate and manage the acquired
businesses quickly and successfully. Acquisitions involve special risks,
including risks associated with unanticipated liabilities, diversion of
management attention, possible adverse effects on earnings resulting from
increased goodwill amortization, potential increased interest costs,
dependence on retention, hiring and training of key personnel and difficulties
relating to the integration of the acquired businesses. Although the Company
believes that it can successfully implement its acquisition program, there can
be no assurance that the Company will be able to identify or acquire
acceptable acquisition candidates on terms favorable to the Company and in a
timely manner to the extent necessary to fulfill the Company's growth
strategy. The Company's ability to achieve and manage its growth will depend
on a number of factors, including the availability of working capital to
support such growth, existing and emerging competition and the Company's
ability to maintain sufficient profit margins. Continued growth could place
additional demands on the Company's administrative, operational and financial
resources. Furthermore, the Company's ability to pay for acquisitions with
stock may be materially limited in the two-year period following the
Separation and the Company's ability to implement its acquisition program may
be adversely affected as a result. There can be no assurance that the Company
will be able to continue to achieve or manage growth effectively, or that
future acquisitions will not have an adverse effect upon the Company's
 
                                       8
<PAGE>
 
business, operating results and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business--Growth Strategy."
 
SEASONALITY; INDUSTRY AND ECONOMIC CYCLES
 
  The Company's business is seasonal. The Company has in the past experienced
seasonal fluctuations in sales and operating results from quarter to quarter.
Operating results are weakest in the first calendar quarter because of the
effects of winter weather on commercial and industrial construction and the
consequent reduction in sales of mechanical insulation and
architectural/acoustical products. Fluctuations in the Company's quarterly
sales and operating results could result in significant volatility in, and
otherwise adversely affect, the market price of the Common Stock. See
"Management's Discussion of Financial Condition and Results of Operations--
Seasonality and Quarterly Results of Operations."
 
  Some of the principal markets for the products and services offered by the
Company are subject to cyclical economic fluctuations that generally affect
pricing, availability and demand for mechanical insulation and
architectural/acoustical products. Cyclical fluctuations could also affect
growth rates in the markets served by the Company's customers, the
availability of products from vendors and the availability of suitable
acquisition candidates. As a result, changes in general economic conditions
could have a material adverse effect on the Company's business, operating
results and financial condition. See "Business--Seasonality and Cyclicality."
 
DEPENDENCE ON SUPPLIER RELATIONSHIPS
 
  The Company's distribution operations are materially dependent on its
relationships with its suppliers. Generally, distribution agreements between
the Company and its suppliers may be terminated without cause by the suppliers
at any time. As a result, even the largest of the Company's suppliers could
terminate the flow of its products to the Company at any time and the Company
would have to obtain substitute products to maintain its reserves. Although
management believes that the Company can maintain its relationships with its
suppliers for the foreseeable future, there can be no assurance that it will
be able to do so. The termination or limitation by any key supplier of its
relationship with the Company could have a material adverse effect on the
Company's business, operating results and financial condition.
 
POTENTIAL RISKS DUE TO CHANGES IN INDUSTRY TRENDS
 
  The distribution industry is undergoing significant change. Historically,
distributors of mechanical insulation and architectural/acoustical products
served primarily as suppliers and extensions of manufacturers' sales forces.
In recent years, both manufacturers and customers have been increasingly
relying on distributors such as the Company to reduce purchasing costs and
provide a broad range of value-added services. As customers increasingly seek
low-cost alternatives to traditional methods of purchasing and sources of
supply, they are, among other things, reducing the number of their suppliers.
Although the Company believes it can maintain current customer relationships,
there can be no assurance that the Company will not lose customers, including
key accounts, as existing customers reduce the number of distributors with
which they do business. Also, distributors are consolidating to achieve
economies of scale and increase efficiencies. This consolidation trend could
cause the industry to become more competitive. The failure by the Company to
respond effectively to such consolidation and increased competition or to
other changes in the industry could have a material adverse effect on the
Company's business, operating results and financial condition. See "Business--
Industry Overview."
 
DEPENDENCE ON IREX INFORMATION SYSTEMS; POTENTIAL SYSTEMS CONVERSION; YEAR
2000 ISSUE
 
  The Company utilizes and will continue to utilize information systems
provided by Irex, which play an integral role in product tracking, pricing and
availability; order processing and shipping; distribution center operations;
purchasing; inventory management; financial reporting; and other financial and
operational functions.
 
                                       9
<PAGE>
 
The Company will enter into an agreement with Irex pursuant to which Irex will
provide information system services to the Company for three years following
the Separation. During such period the Company intends to evaluate its
existing and future information system requirements and examine its options
for obtaining such services. These options include, among others, continuing
the existing relationship with Irex or replacing the Company's current
systems. If the Company decides to install new information systems, there can
be no assurance that it will be able to successfully implement, integrate and
operate such systems without experiencing unanticipated delays, complications
and expenses. Significant disruptions in the Company's information systems or
the failure to successfully complete a conversion to new information systems
on a timely basis could result in operational and financial disruptions and
adversely affect the Company's business, operating results and financial
condition. See "Business--Information Systems."
 
  The Company does not expect to have material exposure to Year 2000
conversion risks following the installation of an upgrade to its information
system software scheduled for October 1998. This planned upgrade has been
installed and tested by the software system vendor in other information
systems and, as a result, the Company believes its information systems will be
Year 2000 compliant following the upgrade. The Company is presently unable to
determine the effects of Year 2000 compliance by its suppliers and customers,
and the failure of suppliers or customers to address such issues effectively
could have a material adverse effect on the Company. See "Business--
Information Systems."
 
POTENTIAL LIABILITY FOR TAXES RELATED TO THE SEPARATION
   
  In connection with the Separation, the Company will enter into a tax sharing
and indemnification agreement with Irex (the "Tax Agreement"). Under the Tax
Agreement the Company will be restricted, for a period of two years following
the date of the Separation, from engaging in certain transactions, including
certain issuances of stock, redemptions of stock or ceasing to engage in its
trade or business, without first obtaining either a ruling from the Internal
Revenue Service or an opinion from nationally recognized tax counsel that such
transaction will not affect the tax-free nature of the Separation to Irex or
its shareholders. The Tax Agreement also requires the Company to indemnify
Irex and its shareholders for tax liabilities that may be incurred by Irex or
its shareholders as a result of actions that the Company may undertake
following the Separation and that cause the Separation to be treated as a
taxable transaction to Irex or its shareholders. Under recently enacted
changes to the Internal Revenue Code applicable to spin-off distributions, a
distributing corporation (Irex) will recognize gain on the appreciation in the
stock of the distributed corporation (the Company) if the distribution is part
of a plan or series of related transactions pursuant to which one or more
persons acquire, directly or indirectly, 50% or more of the voting power or
value of the stock of either corporation. There is a rebuttable presumption
that any acquisitions of stock (including acquisitions through stock issuances
by the Company) occurring during the period beginning two years before and
ending two years after the Separation are part of such a plan (or series if
related transactions). Such presumption may be rebutted by establishing that
the Separation and acquisitions of such stock are not pursuant to a plan or
series of related transactions. Although the Company does not expect these
restrictions to materially inhibit its operations or growth opportunities, if
there is a final determination that any or all of the distributions of Common
Stock effected in connection with the Separation are taxable, the Company
could become liable for a portion of any taxes due in connection with the
Separation to the extent that such tax liability cannot be collected from Irex
or the remaining members of the Irex consolidated group. The Company will also
be required to indemnify Irex and its subsidiaries for specified tax
liabilities otherwise imposed upon or attributable to the Company related to
the Company for periods prior to the Separation. See "Separation from Irex--
Agreements with Irex--Tax Sharing and Indemnification Agreement."     
 
LACK OF ARM'S-LENGTH BARGAINING ON AGREEMENTS WITH IREX
 
  The Company will enter into certain agreements with Irex and its
subsidiaries (the "Separation Agreements") in connection with the Separation
which will set forth the terms of the Separation, the right to utilize Irex's
information system, tax sharing and indemnification, and benefits sharing.
Although management
 
                                      10
<PAGE>
 
of the Company believes that the terms of the Separation Agreements will be
fair to the Company, the terms of the Separation Agreements will be fixed
between Irex and the Company when they are parent and subsidiary and not
independent parties negotiating on an arm's-length basis. Accordingly, there
is no assurance that the terms of the Separation Agreements will be as
favorable to the Company as those that might be obtained from an unaffiliated
third party.
   
POTENTIAL INFLUENCE OF CHAIRMAN OF THE BOARD OF DIRECTORS     
   
  Upon completion of the Offering and Separation, W. Kirk Liddell will
beneficially own approximately 5.5% of the Company's outstanding Common Stock.
In addition, approximately 5.5% of the Company's outstanding Common Stock will
be held by a custodian for Mr. Liddell's minor children. See "Principal
Shareholders." Mr. Liddell will become Chairman of the Board of Directors of
the Company prior to consummation of the Offering. He is also President, Chief
Executive Officer and a director of Irex and the beneficial owner of
approximately 9.3% of issued and outstanding Irex common stock. As a result of
his share ownership of and positions with Irex and the Company, Mr. Liddell
will be in a position to influence the business and affairs of Irex and the
Company. To the extent the Company and Irex have differing interests, Mr.
Liddell could be presented with conflicts of interests in his roles as a
director of each company. There can be no assurance that actions of the
Company taken in the context of such conflicts of interests will be as
favorable to the Company as actions taken in the absence of such conflicts.
       
BENEFITS TO IREX AND ITS AFFILIATES AS A RESULT OF THE SEPARATION AND OFFERING
       
  Irex and its affiliates other than the Company, none of which will be
affiliated with the Company following the Separation and the Offering, will
receive the following benefits as a result of the Separation and Offering:
(i) a $10.5 million cash dividend to be paid by the Company to Irex
immediately prior to the Separation, which dividend will be paid by executing
a note to Irex to be repaid with proceeds of the Offering; (ii) payment of
approximately $9.1 million of debt owed by the Company to Irex or affiliates
of Irex, which will be paid with proceeds of the Offering; and (iii) payment
of $17.8 million owed to Irex pursuant to an intercompany account which the
Company intends to pay with funds borrowed from a credit facility which it
will enter into upon consummation of the Offering. See "Use of Proceeds" and
"Separation from Irex."     
 
COMPETITION
 
  The Company's markets are fragmented and highly competitive, and feature
numerous distribution channels, including national, regional and local
distributors, and local supply houses as well as direct sales by
manufacturers. Many of the Company's competitors are smaller businesses that
sell to customers in a limited geographic area, but the Company also competes
against several significant regional distributors. Certain of the Company's
competitors sell identical or equivalent products at competitive prices, and
the Company also competes on the basis of responsiveness to the needs of
customers for quality service, product diversity and availability. There can
be no assurance that the Company will be able to compete successfully in the
markets in which it operates.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company's operations are highly dependent on the skills, experience and
efforts of its Chief Executive Officer and senior management, and the Company
may depend on the senior management of any significant businesses it acquires
in the future. Although prior to the Offering the Company intends to enter
into employment agreements containing confidentiality and non-competition
provisions with its Chief Executive Officer and other members of its senior
management, the business and prospects of the Company could be adversely
affected if any of these persons does not continue in his position, and the
Company is unable to attract and retain a qualified replacement. See
"Management."
 
ANTI-TAKEOVER PROVISIONS
 
  Certain provisions of Pennsylvania law and the Company's restated articles
of incorporation and bylaws could make it more difficult for a third party to
acquire, or could discourage a third party from attempting to
 
                                      11
<PAGE>
 
acquire, control of the Company. Although the Company has opted out of
Subchapters E, G and H of Chapter 25 of the Pennsylvania Business Corporation
Law of 1988, as amended (the "PBCL"), the Company is governed by Subchapter F
of Chapter 25 of the PBCL, which prohibits the Company from engaging in a
"business combination" with an "interested shareholder" for a period of five
years after the date of the transaction as a result of which such shareholder
became an "interested shareholder," unless the business combination is
approved in a prescribed manner. The Company's restated articles of
incorporation divide the Board of Directors into three classes, each serving a
staggered three-year term. By extending the period of time required to re-
elect or replace the entire Board of Directors, such classification may have
the effect of discouraging persons seeking to effect a takeover or assume
control of the board. In addition, shares of the Company's Preferred Stock,
par value $.01 per share (the "Preferred Stock"), may be issued by the Board
of Directors without shareholder approval on such terms and conditions, and
having such rights, privileges and preferences, as the Board of Directors may
determine. The rights of the holders of the Common Stock may be subject to,
and may be adversely affected by, the rights of the holders of any Preferred
Stock that may be issued in the future. The Company has no current plans to
issue any shares of Preferred Stock and may be otherwise limited in its
ability to issue Preferred Stock in the two-year period following the
Separation. However, the potential issuance of Preferred Stock could have the
effect of delaying, deterring or preventing a change of control of the
Company. See "Description of Capital Stock--Preferred Stock" and "Description
of Capital Stock--Certain Provisions of the Pennsylvania Business Corporation
Law."
 
ABSENCE OF PUBLIC MARKET FOR THE COMMON STOCK
   
  Prior to the Offering, there has been no public market for the Common Stock.
Although the Common Stock has been approved for inclusion on the Nasdaq
National Market, there can be no assurance that an active or liquid trading
market in the Common Stock will develop upon completion of the Offering or, if
developed, that it will be sustained. The initial public offering price of the
Common Stock will be determined through negotiations between the Company and
the Underwriters and may not be indicative of the market price for the Common
Stock after the Offering. The market price for shares of the Company's Common
Stock may be highly volatile and may be significantly affected by such factors
as quarter-to-quarter variations in the Company's results of operations,
changes in general market conditions and other factors. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Quarterly Results of Operations and Seasonality" and "Underwriting."     
 
SHARES ELIGIBLE FOR FUTURE SALE
   
  Sales of a substantial number of shares of Common Stock in the public market
following the Offering and Separation could adversely affect the market price
for the Common Stock. No prediction can be made as to the effect, if any, that
future sales of shares, or the availability of shares for future sale, will
have on the market price of the Common Stock prevailing from time to time. The
number of outstanding shares of Common Stock available for sale in the public
market will be limited by (i) contractual agreements between the Company and
certain shareholders of the Company not to sell for two years the shares of
Common Stock received by them in the Separation; (ii) the lock-up agreements
under which the Company, its officers and directors, and certain Company
shareholders have agreed not to sell or otherwise dispose of any of their
shares for a period of 180 days after the date of this Prospectus without the
prior written consent of Legg Mason Wood Walker, Incorporated, on behalf of
the Underwriters; (iii) limitations relating to the tax-free status of the
Separation (see "--Limitations on Ability Raise Equity Capital and Dependence
on Debt Financing"); and (iv) applicable restrictions under the Securities Act
of 1933, as amended (the "Securities Act"). Upon the consummation of the
Offering, the 2,194,064 shares of Common Stock distributed in the Separation
to nonaffiliates of the Company will be eligible for resale. An additional
719,483 shares of Common Stock will be distributed to affiliates of the
Company and will become eligible for resale following expiration of the
foregoing agreements and restrictions. See "Shares Eligible for Future Sale."
Sales of substantial amounts of Common Stock, including those shares eligible
for sale following the Offering and Separation and those eligible for sale
following the expiration of the foregoing agreements and restrictions, or the
perception that such sales could occur, could adversely affect the prevailing
market price of the Common Stock.     
 
                                      12
<PAGE>
 
                                USE OF PROCEEDS
   
  The net proceeds to be received by the Company from the Offering are
estimated to be approximately $19.6 million (approximately $22.6 million in
the event the Underwriters' over-allotment option is exercised in full),
assuming an initial public offering price of $11.00 per share and after
deducting the estimated underwriting discounts and commissions and estimated
offering expenses payable by the Company. The Company intends to use such
proceeds as follows: (i) to repay approximately $6.3 million of long-term
debt, of which $6.2 million will be paid to Irex; (ii) to repay approximately
$2.8 million of other indebtedness to Irex; (iii) to repay indebtedness
incurred by the declaration of a $10.5 million dividend to Irex in connection
with the Separation; and (iv) for working capital and general corporate
purposes. Rates of interest of the debt to be repaid with such proceeds range
from 6.63% to 9.25% per annum, and the maturity dates of such debt extend from
December 1, 1998 to July 10, 2009. For additional information on the terms of
such debt, see note 7 to the consolidated financial statements of the Company

                                DIVIDEND POLICY
 
  The Company does not plan to pay dividends on its Common Stock in the
foreseeable future and plans to retain any future earnings to finance its
operations and expand its business. Any future determination as to the payment
of cash dividends will be at the discretion of the Company's Board of
Directors and will depend, among other factors, upon the Company's earnings,
financial condition and capital requirements and the terms of the Company's
financing agreements. In addition, the Company's future financing agreement
may contain limitations on the payment of cash dividends.

                                   DILUTION
   
  The net tangible book value (tangible assets minus total liabilities) of the
Company as of March 31, 1998 was $8.0 million, or $2.74 per share of
outstanding Common Stock. After giving effect to the sale of the 2,000,000
shares of Common Stock offered by the Company hereby at an assumed initial
offering price of $11.00 per share (and deducting the estimated underwriting
discount and offering expenses), the pro forma net tangible book value of the
Company as of March 31, 1998 would have been approximately $17.1 million, or
$3.47 per share. This change represents an immediate increase in net tangible
book value of $0.73 per share to the existing shareholders of the Company (the
"Existing Shareholders") and an immediate dilution of $7.53 per share to
investors purchasing shares of Common Stock in this Offering. The following
table illustrates this per share dilution:

for use in the new construction, renovation and maintenance sectors of
industrial and commercial markets. The markets in which the Company competes
have generally exhibited steady and relatively non-cyclical growth due to the
Company's geographic diversity and broad customer base. The Company provides
products and services to customers in a range of industries, including the
general commercial construction, utilities, petro-chemical, pulp and paper,
cold storage, chemical, marine and original equipment manufacturing
industries, among others.     
 
  Historically, the supply markets in which the Company operates have been
highly fragmented and populated by many smaller local and regional
distributors. The industry has begun a trend toward consolidation due
principally to the economies of scale realized by large distributors, the
increasing demand by customers for fewer sources of supply, the benefits of
volume purchasing by larger vendors and demands by customers for additional
value-added services which require substantial investments in technology,
human resources and infrastructure. The Company believes that those
distributors which develop the capabilities and strengths to take advantage of
these trends will be well-positioned to gain market share.
   
  In order to capitalize on its core competencies and take advantage of market
opportunities, the Company has adopted a growth strategy which focuses
primarily on acquiring and opening new distribution centers. The Company
initially adopted a growth strategy to strengthen its presence in regional
markets and has recently begun to implement its strategy on a national scale.
For the three-year period ended December 31, 1997, the Company acquired seven
distribution operations and opened six new distribution centers. Through
targeted acquisitions and distribution center openings, the Company is able to
expand its geographic presence into new markets, meet supplier initiatives and
customer service requirements, pursue strategic opportunities, broaden its
product and service capabilities and take advantage of current industry
dynamics. Distribution centers opened through start-ups or acquisitions during
the three-year period ended December 31, 1997 accounted for approximately
37.2% of the $40.1 million increase in the Company's net sales during that
period. The Company believes that future results of operations will depend in
large part on the Company's ability to continue to make acquisitions on
attractive terms and open new distribution centers in strategic locations, and
then to successfully integrate and manage these new facilities.     
 
  Newly opened distribution centers typically generate an operating loss
during the first one to two years of operations. A greater number of
distribution center openings by the Company in the two-year period ended
December 31, 1997 resulted in a higher percentage of facility and personnel
expenses in 1997 as compared to 1996. However, as the Company generates
incremental volume through acquired or newly opened distribution centers, the
Company believes it will realize improvement in its operating margins by
carrying its fixed costs over a larger revenue base.
 
  On January 19, 1998, Irex announced the Separation. The transaction will
provide the Company with increased flexibility to fund and execute its growth
strategy of internal expansion and acquisitions. The Company's participation
in a consolidating industry, where customers and suppliers desire
relationships with fewer distributors that can provide a range of value-added
products and services, affords additional growth opportunities. The spin off
will create a management team and capital structure devoted solely to
capitalizing on
 
                                      18

these opportunities. The Company has entered into an agreement with Irex which
provides, among other things, for Irex to continue to provide information
services to the Company for a three-year period following the Separation. See
"Separation from Irex."

QUARTER ENDED MARCH 31, 1998 COMPARED TO QUARTER ENDED MARCH 31, 1997     
   
  Net Sales. The Company's net sales increased $6.4 million, or 17.6%, to
$42.7 million in the three months ended March 31, 1998 from $36.3 million in
the three months ended March 31, 1997. Of this increase, approximately $4.6
million, or 71.9%, resulted from the opening of five new distribution centers
and three acquisitions in 1997 and 1998. The remaining $1.8 million, or 28.1%,
is accounted for through volume growth in existing operations.     
   
  Gross Profit. Gross profit increased $1.6 million, or 21.2%, to $9.4 million
in the three months ended March 31, 1998 from $7.7 million in the three months
ended March 31, 1997. As a percentage of net sales, gross profit also
increased to 21.9% from 21.3% over the same period. This increase was
primarily the result of two recent acquisitions in the relatively higher
margin fabrication and industrial mechanical markets. Sales of products
shipped directly from manufacturers, which generate lower margins, decreased
by $2.0 million in the period.     
   
  Selling, General and Administrative Expenses ("SG&A"). SG&A increased 21.3%
to $8.0 million in the three months ended March 31, 1998 from $6.6 million in
the three months ended March 31, 1997. As a percentage of net sales, SG&A
increased to 18.7% from 18.2% over the same period. The higher level of SG&A
is a result of a greater number of acquisitions and new distribution center
openings since December 31, 1996. New distribution centers typically require
expenditures in advance of full revenue generation.     
   
  Interest Expense. Interest expense was $0.5 million in the three months
ended March 31, 1998 as compared to $0.4 million in the three months ended
March 31, 1997. The long-term notes payable to affiliate accounted for $0.2
million of interest expense in both years. The remainder of $0.3 million in
1998 and $0.2 million in 1997 represented the Irex interest charge allocated
to the Company based on the monthly balance in the payable to affiliates
account. The recent acquisitions and increased levels of inventory and
accounts receivable were funded through short-term borrowings with Irex.     
   
  Income Tax Provision. The effective tax rate was 41.0% in the three months
ended March 31, 1998 and 40.8% in the three months ended March 31, 1997. The
Company's tax return is included in the consolidated income tax return of
Irex. However, the Company's income tax provision in 1998 and 1997 is based on
the amount which would have resulted had the Company filed a separate tax
return.     
 
                                      19

  Acquisitions. During the first quarter of 1998, the Company purchased
certain assets of Extol of Texas, Inc. ("Extol") in Houston and Corpus
Christi, Texas. The transaction closed on March 1, 1998 and accounted for
sales of $1.2 million in the quarter ended March 31, 1998. In fiscal year
1997, Extol had net sales of approximately $13.2 million. The quarter ended
March 31, 1998 also included the results of operations of Constructions
Systems, Inc. from which the Company purchased certain assets on December 8,
1997. Net sales for the first quarter 1998 aggregated $2.4 million.     
       
       
          
SUBSEQUENT EVENTS     
          
  On May 13, 1998, the Company executed a letter of intent to purchase certain
assets of a mechanical insulation fabricator with fiscal year 1997 sales of
approximately $4.0 million.     
       
YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
   
  Net Sales. The Company's net sales increased $16.7 million, or 11.8%, to
$158.5 million in 1997 from $141.8 million in 1996. Of this increase,
approximately 34.4% was attributable to sales volume from six distribution
centers opened in 1996 and 1997. Growth from existing operations accounted for
approximately 39.0% of the increase in net sales as volume remained strong
across each of the Company's primary lines of business. Export sales, which
primarily consist of sales to domestic exporters and are included in the
growth from existing operations, comprised 10.0% of the Company's net sales
and contributed $5.0 million of this increase. The remaining increase in net
sales, representing $4.4 million, resulted from six acquisitions completed
during the two-year period ended December 31, 1997.     
   
  Gross Profit. Gross profit increased 10.1% to $34.3 million in 1997 from
$31.1 million in 1996. As a percentage of net sales, the gross profit
decreased slightly to 21.6% from 21.9% in 1996. The slight decrease was
primarily the result of greater sales of products shipped directly from
manufacturers to the customers ("direct-ship business"), which generate lower
margins for the Company. Management does not expect direct-ship business to
increase as a percentage of total sales.     
   
  Selling, General and Administrative Expenses. SG&A primarily consist of
personnel-related expenses and facility lease and operating expenses. SG&A
increased 10.0%, to $27.2 million in 1997 from $24.8 million in 1996. As a
percentage of net sales, SG&A decreased to 17.2% in 1997 from 17.4% in 1996.
The improvement was generally the result of a decrease in the provision for
losses on accounts receivable as the Company has made significant efforts
toward improving the quality of its credit portfolio. This decrease in the
loss provision was partially offset by increases in personnel and facility
lease expenses due to newly opened distribution centers.     
   
  It is the Company's practice to determine the need for specific reserves
based on a review of all account balances exceeding specified parameters. In
addition, a non-specific reserve is maintained for all accounts not
specifically reviewed. During 1995 and 1996, there were several accounts which
were specifically reviewed by management and determined to require specific
reserves. At December 31, 1997 the number of problem accounts, those subject
to specific reserve review, declined due to a concentrated effort to improve
the credit quality and collection process. The success of this overall effort
is evidenced by the decline of days sales outstanding from 69.7 days at
December 31, 1995 to 63.5 days at December 31, 1997.     
   
  The method used to establish the non-specific reserve during this same
period remained unchanged.     
 
  Interest Expense, Net. Interest expense was $1.9 million in both 1997 and
1996. A portion of the interest expense was attributable to the long-term
notes payable to affiliate, which accounted for $0.7 million of interest
expense in both 1997 and 1996. The remaining interest expense was primarily
associated with the payable to affiliates account. Based upon the activity in
this account, Irex charged the Company interest of $1.2 million in 1997 and
$1.1 million in 1996.
 
 
                                      20

  Income Tax Provision. The effective tax rate was 40.9% in 1997 and 40.3% in
1996. The Company's tax return is included in the consolidated income tax
return filed by Irex. However, the Company's income tax provision is based on
the amount which would have resulted had the Company filed a separate tax
return.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
  Net Sales. The Company's net sales increased $23.4 million, or 19.8%, to
$141.8 million in 1996 from $118.4 million in 1995. Higher sales volume at
existing centers accounted for approximately 80.9% of the increase. Export
sales, included in the growth from existing centers, increased to $11.0
million in 1996 from $2.0 million in 1995. The increase in export sales was
primarily the result of sales made to two domestic exporters of products
destined for Russia. Three distribution centers opened in 1996 contributed
approximately 7.5% of the increase. The remaining increase in net sales,
representing $2.7 million, resulted from four acquisitions completed during
the two-year period ended December 31, 1996.
   
  Gross Profit. Gross profit increased 20.2% to $31.1 million in 1996 from
$25.9 million in 1995. As a percentage of net sales, the gross profit remained
stable at 21.9% in both 1996 and 1995. An increase in direct-ship business,
which carries lower gross margins, was offset by higher gross margins on the
sales of fabricated products.     
   
  Selling, General and Administrative Expenses. SG&A increased 13.4% to $24.8
million in 1996 from $21.8 million in 1995. The increase was primarily
attributable to higher personnel expenses from the opening of new distribution
centers, the pursuit of new industrial customers in the Southwest and the
securing of a new national account as reflected in the increase in sales
volume. However, as a percentage of net sales, SG&A decreased to 17.4% in 1996
from 18.4% in 1995. This decrease was primarily due to the ability of the
Company to increase sales without a corresponding increase in its overhead
structure.     
 
  Interest Expense, Net. Interest expense remained relatively unchanged in
1995 and 1996 at $1.9 million. A portion of the interest expense was
attributable to the long-term notes payable to affiliate, which accounted for
interest expense of $0.7 million in 1996 and $0.8 million in 1995. The
remaining interest expense was primarily associated with the payable to
affiliates account. Based upon the activity in this account, Irex charged the
Company interest of $1.1 million in 1996 and $1.0 million in 1995.
 
  Income Tax Provision. The effective tax rate was 40.3% in 1996 and 41.5% in
1995. The Company's tax return is included in the consolidated income tax
return filed by Irex. However, the Company's income tax provision is based on
the amount which would have resulted had the Company filed a separate tax
return.

</TABLE>    
 
  The Company expects to experience significant fluctuations in its future
quarterly operating results due to a variety of factors, many of which are
outside the Company's control. The primary factor that may affect the
Company's quarterly operating results is lower sales volumes in the first
quarter due to winter weather conditions in certain regions of the country,
which reduces the number of new construction, renovation and maintenance
projects and consequently decreases demand for the Company's products and
services.
 
LIQUIDITY AND CAPITAL RESOURCES
   
  The Company has primarily relied on cash flow from operations and borrowings
from the Company's affiliates prior to the Separation to finance its
operations. During the quarter ended March 31, 1998, net cash provided by
operating activities totalled $4.4 million as compared to $0.9 million in the
first quarter of 1997. The increase was primarily a result of an increase in
accounts payable and the increase in accounts receivable as a result of sales.
Net cash used for investing activities totalled $5.7 million in the first
quarter of 1998 as compared to $0.1 million in the comparable period in 1997.
The 1998 period reflects the acquisition which resulted in goodwill of
approximately $0.7 million which will be amortized over 15 years. The net cash
provided from financing activities in the first quarter of 1998 was a result
of borrowings from affiliates.     
   
  Net cash provided by operating activities totaled $1.2 million during 1997
compared to $1.9 million during 1996. The decrease was primarily attributable
to an increase in accounts receivable, partially offset by an increase in
accounts payable, each of which resulted from the Company's higher sales
volume. While the balance for receivables and inventories has increased as a
result of the growth in sales and the number of distribution centers, the
Company's focus on effective asset management has led to an improvement in

receivable, improved to 5.7x in 1997 from 5.2x in 1995. Inventory turnover,
exclusive of sales shipped directly from manufacturers to customers, increased
to 7.2x in 1997 from 6.7x in 1995.
 
  Net cash used for investing activities totaled $4.0 million in 1997 and $0.8
million in 1996. The Company completed three acquisitions in the fourth
quarter of 1997 for aggregate cash consideration of $3.5 million, which
collectively resulted in goodwill of approximately $0.9 million that is being
amortized principally on a straight-line basis over 15 years. Capital
expenditures totaled $0.6 million in each of 1997 and 1996.
   
  Net cash provided by financing activities totaled $3.2 million in 1997
compared to net cash used of $1.1 million in 1996. The $4.2 million change was
attributable to an increase in the Company's payable to affiliates account.
During 1997 and 1996, the Company made debt repayments of $1.2 million to an
affiliate of the Company.     
   
  As of March 31, 1998 the Company had, and as of the date of this Prospectus
the Company has, no material commitments for capital expenditures.     
   
  The Company expects to enter into a four-year committed revolving credit
facility agreement in connection with and prior to consummation of the
Offering. The credit facility is expected to provide an aggregate of $30
million in senior unsecured debt at an interest rate subject to quarterly
adjustment to reflect the Company's debt level as a function of its operating
results. The Company expects that funds from operations and availability under
the credit facility will be sufficient to meet its working capital and growth
strategy requirements for the foreseeable future. The remaining net proceeds
of the Offering after payment of the debt incurred to pay the dividend to Irex
will be utilized to repay long-term and a portion of the short-term borrowings
from Irex. Long-term borrowings from Irex currently are approximately $6.2
million. The Company plans to utilize funding from the credit facility to
repay the short-term borrowings from affiliates and for general working
capital. The credit facility will also be utilized to finance acquisitions
including related working capital requirements. The Company is currently
evaluating the utilization of an interest rate swap to effectively convert a
portion of the funding to a fixed rate.     
 
INFLATION
 
  The Company does not believe that inflation has had a material effect on its
results of operations in recent years. There can be no assurance, however,
that the Company's business will not be affected by inflation in the future.
 
YEAR 2000 ISSUE
 
  The Company utilizes information systems owned and maintained by Irex. The
Company's ability to conduct its day-to-day operations is dependent in part on
an integrated software program and data-based system, which serves as a
critical tool in carrying out functions in several key areas of the business,
including inventory management, pricing, sales, financial reporting and
personnel administration.
 
  The Company has entered into an agreement with Irex pursuant to which Irex
will continue to provide information services to the Company on a fee for
services basis for a three-year period subsequent to the Separation. See
"Separation from Irex--Agreements with Irex."
 
  The Company has reviewed all of its current computer applications with
respect to the Year 2000 issue. The Company believes all of its relevant
applications will be Year 2000 compliant following the installation of an
upgrade to the system software scheduled for October 1998. The Company
believes that any additional costs with respect to Year 2000 compliance will
not be material to the Company. The Company is unable to determine the effects
of Year 2000 compliance by its suppliers and customers.

                     ACQUISITION AND EXPANSION BACKGROUND
 
  Two key components of the Company's growth strategy have been acquisitions
and the opening of distribution centers. Historically, the Company grew as it
solidified its presence in regional markets by opening new distribution
centers or acquiring business operations with well-developed market positions.
More recently, the Company has begun to implement a growth strategy executed
on a national scale. Through targeted acquisitions and distribution center
openings, the Company pursues opportunities to expand its presence in new
geographic areas with strong growth characteristics. The Company believes that
being a broadly based national distributor provides it with a competitive
advantage over regional and local competitors, especially in servicing
customers with multiple locations that desire a single-supplier relationship.
This strategy has enabled the Company to further penetrate existing markets,
broaden its product and service capabilities and take advantage of current
industry dynamics. The Company believes that these components of its growth
strategy have been significant factors in producing compound annual growth
rates in net sales and operating income of 14.6% and 57.7%, respectively, for
the five-year period ended December 31, 1997.
   
  For the five-year period ended December 31, 1997, the Company acquired 11
distribution operations (including three from affiliates), which together
contributed approximately $13.2 million, or 8.3%, to the Company's 1997 net
sales. During the same period, the Company opened 10 distribution centers,
which together contributed approximately $12.3 million, or 7.8%, to the
Company's 1997 net sales. Since January 1, 1998, the Company has completed one
acquisition and opened three distribution centers. The Company has entered
into a letter of intent to purchase certain assets of a mechanical insulation
fabricator with fiscal year 1997 net sales of approximately $4.0 million.     
 
  The Company pursues acquisitions and opens distribution centers as the
result of strategic opportunities. In addition, the Company's approach to
acquisitions and distribution center openings is influenced by the following
factors:
 
    Expand Product Lines and Broaden Technical Expertise. The Company is able
  to expand its product lines and broaden its technical expertise through
  acquisitions. The Company believes that its national infrastructure allows
  it to add new product lines and capabilities for existing customers without
  incurring significant additional cost.
 
    Service Customer Requirements. The Company opens distribution centers and
  pursues acquisitions in regions where it can better serve its existing
  customers' product requirements. Once operational, the Company seeks to
  drive incremental volume through these locations.
 
    Pursue Market Opportunities. The Company opens distribution centers in
  locations where it believes volume levels can support stand-alone
  operations. Such opportunities may result from general economic growth in
  particular regions or product lines, inadequate servicing of markets by
  competitors and other factors identified in the Company's experience.
 
    Respond to Supplier Initiatives. Acquisitions and distribution center
  openings also result from the Company's strong relationships with its
  suppliers. Through these relationships the Company becomes an integral part
  of suppliers' expansion strategies. The Company works together with its
  suppliers to serve their common growth strategies and increase its market
  share.
 
  The Company's management has significant experience integrating acquired and
newly opened operations into its nationwide business. Following acquisitions,
the Company attempts to eliminate redundancies, conform inventory and
administrative practices, streamline administrative functions and systems,
leverage purchasing power and improve asset management. Similarly, new
distribution centers are opened with the goal of increasing operating
efficiencies. Once a site and operating management have been identified for a
new location, the Company expects new distribution centers can be operational
within 30 days after investments of approximately $25,000 in start-up costs
and approximately $50,000 in initial inventory. Historically, the Company has
found that successful new distribution center operations, on average, break
even during the second year and become profitable during the third year after
start-up.

INTRODUCTION
   
  Specialty Products & Insulation Co. is a leading national distributor and
fabricator of mechanical insulation, architectural/acoustical products and
specialty products to commercial and industrial markets. The Company also
offers customized fabrication, export and other value-added services related
to its core product lines. The Company operates through a national network of
52 distribution centers, including seven fabrication facilities, at
strategically chosen locations in 21 states. Through this network, the Company
offers approximately 25,000 stock keeping units to more than 9,000 customers,
including specialty contractors, facility owners, general contractors,
original equipment manufacturers ("OEMs"), exporters and supply houses. The
Company's principal product categories include piping and equipment insulation
as well as acoustical ceilings and specialty wall panels, and include the
products of more than 150 manufacturers including Armstrong World Industries,
Owens Corning, Johns Manville, Dow Chemical and Pittsburgh Corning. Since
commencing operations in the early 1980s, the Company has experienced
significant growth as a result of its ability to capitalize on industry
changes including, principally, the increased reliance on distributors by
manufacturers and customers. Net sales of the Company increased from $118.4
million in 1995 to $158.5 million in 1997, and operating income grew from $4.1
million in 1995 to $7.0 million in 1997. In the first three months of 1998,
net sales and operating income totalled $42.7 million and $1.4 million,
respectively, as compared to $36.3 million and $1.1 million respectively, in
the first three months of 1997.     
 
INDUSTRY OVERVIEW
 
  The Company competes in the highly fragmented and consolidating commercial
and industrial segment of the building products industry. The Company broadly
defines its two core markets as mechanical insulation, consisting primarily of
pipe, duct and equipment insulation and architectural/acoustical products,
consisting primarily of acoustical ceiling systems, fiberglass-reinforced
panels and other wall and ceiling products. The Company participates in the
commercial and industrial markets by supplying products for use in (i) new
construction, (ii) renovation of existing facilities, (iii) ongoing
maintenance and (iv) OEM applications.
 
  The channels of supply in the Company's markets have experienced significant
change. In the early 1980s, product sales in the Company's markets were
characterized by direct sales from manufacturers to contractors who in turn
sold the products to other contractors and end-users. An expanding and
increasingly diverse customer base made it difficult for the typical
manufacturer to directly serve its entire potential customer universe. Also,
as manufacturers realized opportunities to enhance profitability and improve
returns on capital, the need for independent distributors evolved. Through
this evolution, independent distributors have enabled manufacturers to reduce
logistical expenses, lower marketing expenses and better manage inventories.
In addition, customers began to utilize independent distribution sources in
order to lower costs, reduce supply sources and gain high-quality, value-added
services. Customers are increasingly outsourcing non-core business functions
to distributors able to provide value-added services such as procurement,
delivery and inventory management. The emergence of the distribution channel
has reduced duplicate functions performed by both manufacturers and customers,
thereby affording them more resources for their core competencies.
 
  The evolution toward independent distribution has produced an industry
populated by many smaller local and regional distributors. The Company
believes the industry is now starting to undergo a significant trend toward
consolidation of these smaller distributors as both suppliers and customers
seek to enhance efficiencies, focus on their core competencies and reduce
costs while maintaining high levels of product and service quality. The
Company believes that those distributors that develop the capabilities and
strengths to satisfy these demands will be well positioned to exceed market
growth rates in this industry. Specifically, the Company believes that large,
national distributors with significant volumes, sophisticated information
systems and relatively low infrastructure costs can offer more value to
customers and therefore gain higher market share.
 
  Key customer categories in the markets served by the Company include the
following:
 
    Specialty Contractors, such as insulation and acoustical contractors,
  constitute the primary customer segment for the installation and
  maintenance of mechanical insulation and architectural/acoustical systems.
 
                                      27
<PAGE>
 
  The Company believes specialty contractors are increasingly developing
  long-term relationships with distributors in order to improve labor
  productivity, eliminate inventories and reduce material handling costs.
 
    Facility Owners, such as manufacturing and process plants, large
  retailers, universities and other institutions, represent a growing source
  of business for distributors as these customers increasingly separate
  material and labor purchases and perform their own maintenance and new
  construction. The Company believes that facility owners with locations
  nationwide value distributors that can provide products and services to
  multiple locations.
 
    General Contractors, such as mechanical contractors and engineering
  firms, are increasingly purchasing materials for their projects and
  performing their own insulation work. The Company believes these customers
  seek distributors with strong sourcing capabilities, processes and
  information systems.
 
    Original Equipment Manufacturers, such as manufacturers of appliances,
  modular office equipment and air conditioning systems, benefit from the
  purchasing, fabrication, material handling, inventory management,
  procurement and delivery capabilities of larger distributors.
 
    Exporters, representing purchasers of materials required for projects
  overseas, benefit from the product knowledge, purchasing power,
  consolidation capabilities and delivery flexibility of large distributors.
 
    Supply Houses, such as plumbing wholesalers, are generally distributors
  in specialized fields that re-sell products to other customer groups. These
  customers include specialty and integrated suppliers that may benefit from
  the purchasing, warehousing and service capabilities of larger, more
  sophisticated distributors.
 
  Mechanical Insulation Products. The mechanical insulation product market
includes thermal insulation materials and systems for use in the commercial
and industrial sectors of the construction industry as well as OEM
applications. Mechanical insulation is used in new construction, maintenance,
renovation and upgrades of manufacturing facilities, process plants,
commercial buildings and mechanical equipment. These products enable customers
to improve the performance of their mechanical systems and products, reduce
energy costs, decrease emissions, such as carbon dioxide and sulfur dioxide,
and improve the comfort and safety of the work environment. According to the
American Society of Heating, Refrigerating and Air Conditioning Engineers
("ASHRAE"), current insulation practices in the United States often result in
the under-insulation of equipment, commercial buildings and industrial
facilities. If such equipment, buildings and facilities were insulated at the
ASHRAE standard, the Company believes that significant reductions in energy
consumption, utility costs and carbon dioxide emissions could be achieved.
 
  Architectural/Acoustical Products. The architectural/acoustical product
market includes ceiling panels and grid systems and specialty wall panels for
the new construction, renovation and retail market segments. These products
are used in commercial office buildings, education facilities, health care
institutions, entertainment complexes and correctional facilities. Independent
estimates forecast that the strongest areas of future growth in the
nonresidential construction market include hotels, educational and public
administration facilities. The ceiling systems segment includes acoustical and
decorative ceilings and suspension systems. Ceiling systems provide an array
of design option benefits to the customer such as acoustic performance, fire
resistance, humidity resistance, light reflectance and durability or ease of
maintenance. The specialty wall segment includes decorative, acoustical and
specialized panels designed for specific uses such as trade show dividers,
modular office systems and kitchen, bath and clean room environments. Many
specialty products are included within this market, the largest component
being passive firestop and fire protection products which are used in new
construction and renovation projects for occupancy safety and property
protection.
 
OPERATING STRATEGY
 
  The Company is focused on its traditional strengths as a broadly based
national distributor and fabricator of mechanical insulation,
architectural/acoustical products, specialty products and value-added
services. The Company is committed to capitalizing on the expertise, knowledge
and experience its has developed in these
 
                                      28
<PAGE>
 
core markets to increase market share and profitability. In addition, the
Company's operating strategy includes the following key elements:
 
  Superior Customer Service. Customers choose suppliers based, in significant
part, on the quality of the service provided. With distribution and sales
forces in each area that it serves, the Company provides its customers with
rapid delivery and localized service. The Company believes its well-trained,
technically competent workforce provides a level of customer service that
leads to long-term relationships with its customers. The Company also believes
that the ongoing assessment of customer satisfaction is critical in the
distribution industry. The Company has implemented a customer satisfaction
survey program and is committed to the ongoing measurement of customer
satisfaction.
 
  National Network of Distribution Centers. Management believes the Company's
national distribution network provides a platform for growth and
profitability. The Company's 51 distribution centers combine warehouse and
office facilities at strategically chosen locations in 21 states. This
national network enables the Company to (i) attract customers that have
multiple locations and provide them with services from multiple distribution
centers within a single service agreement; (ii) participate with key vendors
in the development of national marketing and sales strategies; (iii) achieve
geographic diversification to lessen the impact of reduced demand in any given
region; and (iv) facilitate best-practice benchmarking as well as innovation
and knowledge-sharing within the Company. Management believes the Company's
national network provides it with a unique competitive advantage.
 
  Strong Supplier Relationships. The Company believes that it has excellent
and long-term relationships with its major suppliers. The Company believes its
national presence, financial strength and partnering philosophy have enabled
the Company to become the preferred distributor for many of its suppliers. The
Company works with its suppliers to develop common expansion programs as well
as customer-oriented product solutions.
   
  Low Cost of Operations. The Company believes that its volume of purchases
and desirability as a vendor enable it to obtain purchase terms that are as
favorable as those available to other large competitors. The Company is also
able to realize advantages from the economies of large-scale operation in the
areas of administrative processing, information systems, financing terms,
technical expertise, inventory and working capital management.     
 
  Innovative and Committed Employees. Management believes the Company's
corporate culture and values provide it with a competitive advantage. The
Company is focused on recruiting, developing and retaining highly innovative
and committed employees. The Company's senior management has an average of
approximately 10 years' experience with the Company, and many of its sales and
service staff have been working in the same markets for 10 years or more.
 
GROWTH STRATEGY
 
  The Company believes that its operating strategy provides a foundation for
growth in each of the markets in which it participates. The Company's growth
strategy includes the following key elements:
 
  Increase Sales of Existing and Accessory Products. Management believes the
Company's strengths and operating strategies will lead to increased sales of
existing products to its existing customer base. In addition, the Company
believes that expansion through acquisitions, new distribution center openings
and other strategic initiatives will generate additional sales of existing
products to new customers. Through improved sales efforts, the Company is also
focused on increasing sales of accessory products, such as adhesives and
tools, which are related to its core product lines and customer requirements.
 
  Open New Distribution Centers. The Company expects to continue to open new
distribution centers as a result of new market opportunities, customer service
requirements, supplier initiatives and strategic opportunities.
 
                                      29
<PAGE>
 
As the Company continues to broaden its national distribution network through
additional openings, the Company believes it will be able to capitalize on
operating efficiencies and the benefits of a large-scale operation.
 
  Continue Acquisitions. The Company is committed to continuing its
acquisition program to acquire distribution businesses with strong market
positions, supplier support or attractive customer bases. Acquisitions allow
the Company to accelerate revenue growth, expand its geographical presence and
add product lines and technical expertise. The distribution industry continues
to consolidate, and management believes the Company will be able to capitalize
on significant growth opportunities through acquisitions of smaller regional
and local distribution operations.
 
  Emphasize National Accounts. The Company has implemented a national accounts
marketing program directed at facility owners and general contractors.
Management believes that the Company's national distribution network gives the
Company a competitive advantage in securing national and multi-regional
customers seeking to reduce vendors, outsource non-core operations, integrate
supply and gain value-added services such as procurement and material
management.
 
  Add Product Lines. The Company intends to leverage its core product and
technical expertise to add product lines which are complementary to those
currently offered. The Company believes that its existing national
distribution infrastructure enables it to add new product lines without
incurring significant additional cost. For example, the Company utilized its
expertise in both of its core product lines to enter the passive fire
protection market.
 
PRODUCTS AND SERVICES
 
  The Company offers complete lines of mechanical insulation,
architectural/acoustical products and specialty products as well as customized
fabrication solutions and other value-added services, enabling it to satisfy a
broad range of customer requirements. In all, the Company offers approximately
25,000 stock keeping units from more than 70 product lines, including those of
the leading manufacturers in the industries it serves. The Company believes it
offers significant depth and breadth in its core product lines throughout its
nationwide operations, enabling customers to satisfy most, if not all, of
their product needs through a single source.
 
  In addition, as the distribution industry continues to evolve and
consolidate, customers are increasingly relying on the Company to perform
various value-added services in connection with product distribution. The
Company's fabrication business represents its most significant value-added
service to customers. Its fabrication capabilities extend across all major
product lines and include custom-fitted pipe covering, decorative wall panels
and precision die-cutting. The Company also offers a range of other value-
added services, including energy audits, technical advice, materials handling
and electronic order processing.

CUSTOMERS
   
  The Company currently serves more than 9,000 customers, including specialty
contractors, facility owners, general contractors, OEMs, exporters and supply
houses. The Company's top 10 customers (including two affiliates) in terms of
net sales accounted for approximately 17% of net sales in 1997, and no single
customer accounted for more than 5% of net sales in 1997.     
 
DISTRIBUTION NETWORK
   
  The Company's distribution network is organized into eight regional
territories encompassing 52 distribution centers in 21 states. Regional
managers are members of the Company's senior management team and have
responsibility for overall operations within each region. Each individual
service center has its own customer-focused team that typically consists of a
branch manager, outside and inside sales representatives and customer service
representatives who include distribution center driver teams and support
staff. The Company's branches are organized as autonomous, decentralized units
and are capable of meeting local market needs as well     
 
                                      31
<PAGE>
 
as offering competitive prices within the Company's overall policies. Each
branch handles one or more of the Company's product groups and operates as a
separate profit center. Branch managers have the authority and responsibility,
within Company guidelines, to set pricing and tailor the facility's product
offering and mix, as well as the nature of services offered to meet the local
market environment. In addition, each branch manager is responsible for
purchasing, maintenance of adequate inventory levels, cost controls and
customer relations. Common accounting, information systems, insurance, tax and
other administrative functions are provided at the corporate level to
eliminate duplicate administrative expenses.
 
SALES AND MARKETING
   
  The Company has approximately 88 outside sales representatives, including
branch managers, and 87 inside sales/customer service representatives.
Generally, the inside sales/customer service representatives support the
outside sales representatives and have independent sales responsibility,
including specific customer service and order entry duties. Each outside sales
representative works in an assigned sales territory associated with one of the
Company's 52 distribution facilities and is actively supported by the branch
and regional teams. National accounts are supported by two specialists and the
Company's senior management in conjunction with the total distribution
network. All sales representatives are employees of the Company and are
generally compensated on a salary and incentive-based compensation
arrangement. The incentive portion of the salesperson's compensation is based
on a return-on-assets model and averages above 20% of base compensation.     
 
  The Company also markets its products through sales brochures, customer
events, occasional sales promotions, and its Internet web site at
http://www.spi-co.com.
   
  The Company's return and allowance policy generally provides for the return
of standard inventoried products that do not satisfy customer requirements,
provided they are in resalable condition, or products which do not meet
quality standards. Special-order and fabricated products cannot be returned.
The customer is responsible for applicable freight costs and a handling charge
may be levied against the return, depending upon the Company's agreement with
the customer. The Company's suppliers maintain similar policies with the
Company. The Company's experience with returns and allowances has not had a
material effect on the Company's business or financial condition.     
 
SUPPLIERS
 
  The Company has a broad base of approximately 150 suppliers that includes
all major manufacturers in the industries the Company serves. The Company's
leading suppliers of mechanical insulation include Owens-Corning Fiberglas,
Johns Manville, Armstrong World Industries, Dow Chemical, CertainTeed, H.B.
Fuller, Pittsburgh Corning, Thermal Ceramics, Calsilite Group, Childers
Products, RPR Industries and RBX Corporation, among others. The Company's
leading suppliers of architectural/acoustical products include Armstrong World
Industries, STO, National Gypsum, Kemlite, Lasco and Sequentia, among others.
 
INFORMATION SYSTEMS
 
  The Company utilizes information systems owned and maintained by Irex. The
systems use software that unites the Company's distribution centers and
integrates product tracking, pricing and availability; order processing and
shipping; distribution center operations; purchasing; inventory management;
receivables management; financial reporting; and other financial and
operational functions. A new release of the system software has been fully
tested by other customers of the system vendor and is scheduled to be
installed in 1998 to address Year 2000 compliance issues and provide other
function upgrades. See "Risk Factors--Dependence On Information Systems;
Systems Conversion; Year 2000 Issue."
 
  The Company has entered into an agreement with Irex pursuant to which Irex
will continue to provide information system services to the Company on a fee-
for-services basis for a three-year period following consummation of the
Offering and Separation. During such period the Company intends to evaluate
its existing
 
                                      32
<PAGE>
 
and future information system requirements and examine its options for
obtaining such services. These options include, among others, continuing the
existing relationship with Irex or replacing the Company's current systems.
See "Separation from Irex--Agreements with Irex--Corporate Separation
Agreement."
 
COMPETITION
 
  The Company's markets are highly competitive. Historically, the markets in
which the Company participates have been highly fragmented and populated by a
large number of smaller, local and regional distributors operating in single
geographic areas. These smaller, often owner-operated, distributors have
constituted the principal competition to the Company, but other significant
competitors include regional distributors as well as manufacturers selling
directly to end-users. Certain of the Company's competitors sell identical or
equivalent products at competitive prices, and the Company also competes on
the basis of responsiveness to the needs of customers for product quality,
service, product diversity, and availability.
 
SEASONALITY AND CYCLICALITY
 
  The Company's business is seasonal and in the past has experienced seasonal
fluctuations in sales and operating results from quarter to quarter. Operating
results are weakest in the first calendar quarter because of the effects of
winter weather on commercial and industrial construction and the consequent
reduction in sales of mechanical insulation and architectural/acoustical
products. Fluctuations in the Company's quarterly sales and operating results
could result in significant volatility in, and otherwise adversely affect, the
market price of the Common Stock. See "Management's Discussion of Financial
Condition and Results of Operations--Seasonality and Quarterly Results of
Operations."
 
  Some of the principal markets for the products and services offered by the
Company are subject to cyclical economic fluctuations that generally affect
pricing, availability and demand for mechanical insulation and
architectural/acoustical products. Cyclical fluctuations can also affect
growth rates in the markets served by the Company's customers, the
availability of products from vendors and the availability of suitable
acquisition candidates. As a result, changes in general economic conditions
could have a material adverse effect on the Company's business, operating
results and financial condition. See "Risk Factors--Seasonality; Industry and
Economic Cycles."
 
EMPLOYEES
   
  On May 20, 1998, the Company had 556 employees, including 138 sales
representatives, 245 distribution center, delivery, clerical and support
personnel, 113 fabrication personnel and 60 supervisors and managers,
including the Company's executive officers. None of the Company's employees is
covered by a collective bargaining agreement. Management considers the
Company's relations with its employees to be good.     
 
PROPERTIES
   
  The Company leases all of its office and distribution center space. The
typical distribution center lease is for a three- to five-year term and
requires the Company to pay all ongoing expenses such as taxes, utilities,
insurance and maintenance expenses. The following table sets forth certain
information with respect to the Company's significant distribution and
fabrication facilities:

LEGAL PROCEEDINGS
 
  The Company is not currently a party to any material litigation. In the
ordinary course of its business, the Company is from time to time involved in
various contractual, warranty, product liability and other cases and claims.
None of the cases currently pending are expected, individually or in the
aggregate, to have a material adverse effect on the Company's business,
operating results or financial condition.
 
REGULATORY MATTERS
 
  The Company's operations and properties are subject to federal, state, local
and foreign laws, regulations and ordinances relating to the use, storage,
handling, generation, transportation, treatment, emission, release, discharge
and disposal of certain materials, substances and wastes, including laws
pertaining to employee health and safety in connection with the foregoing.
 
  Based upon the Company's experience to date, the Company believes that the
future cost of compliance with existing environmental and employee health and
safety laws, regulations and ordinances will not have a material adverse
effect on the Company's business, operating results or financial condition.
However, future events, such as changes in existing laws and regulations or
their interpretation, may give rise to additional compliance costs or
liabilities that could have a material adverse effect on the Company's
business, operating results and financial condition. Compliance with more
stringent laws or regulations, as well as more vigorous enforcement policies
of regulatory agencies or stricter or different interpretations of existing
laws, may require additional expenditures by the Company that may be material.

(1) All options are options to purchase Irex common stock pursuant to the Irex
    Corporation Non-Qualified Stock Option Plan.     
 
STOCK OPTION PLAN
   
  Prior to consummation of the Offering, the Company intends to adopt the 1998
Specialty Products & Insulation Co. Stock Option Plan (the "Plan"), which is
expected to provide for the granting of non-qualified stock options
("Options") to certain officers and key employees of the Company. The Plan may
also permit the Company to issue qualified stock options or stock appreciation
rights. The Plan will be administered by the Compensation and Benefits
Committee of the Board of Directors of the Company (the "Compensation and
Benefits Committee"). The aggregate maximum number of shares of Common Stock
available for awards under the Plan will be 491,355 shares (521,355 shares if
the Underwriters exercise their over-allotment option in full), subject to
adjustment to reflect changes in the Company's capitalization. The Company
intends to award approximately 25% of the maximum number of shares available
under the Plan during the first year after the Plan is adopted and may award
the remaining shares available under the Plan during the following nine years.
No awards can be made under the Plan more than 10 years after the date it is
adopted.     
   
  The exercise price of the Options will be determined by the Compensation and
Benefits Committee in its discretion, provided that the exercise price of any
Option cannot be less than the fair market value of a share of Common Stock on
the date such Option is granted. Options will vest and may be exercised three
years after the date of grant. No Option may be exercised more than 10 years
after the date of grant. The Options may not be exercised following
termination of the grantee's employment with the Company, except that in the
event a grantee's employment terminates due to death, disability or
retirement, options held by such grantee or his or her estate shall be
exercisable, if vested at the time of termination of employment, for a period
of three months after termination.     
       
                                      38
<PAGE>
 
   
  In connection with the Offering, the Compensation and Benefits Committee is
expected to approve the grant of Options to certain officers and employees of
the Company to purchase an aggregate of     shares of Common Stock under the
Plan, including grants of options to purchase    shares,     shares and
   shares of Common Stock to Messrs. King, Schattgen and Horan, respectively.
The exercise price of these options is expected to be at the offering price.
    
401(K) PLAN
 
  Prior to consummation of the Offering the Company expects to adopt the
Employees' Savings Incentive Plan (the "401(k) Plan"). The 401(k) Plan is a
savings and retirement plan intended to satisfy the tax qualification
requirements of Section 401(a) of the Internal Revenue Code of 1986, as
amended (the "Code"). Subject to certain terms and conditions of the 401(k)
Plan, substantially all of the Company's employees who are employed on the
date of the consummation of the Separation and who are compensated on the
basis of a monthly salary will be immediately eligible to participate in the
401(k) Plan. Thereafter, salaried employees will be eligible to participate in
the 401(k) Plan on the January 1 or July 1 coincident with or next following
the date on which the employee is hired by the Company. Eligible employees may
contribute between 2% and 15% of their compensation to the 401(k) Plan on a
pre-tax or after-tax basis.
 
  The Company will make matching contributions to the 401(k) Plan each year
equal to 100% of the first 3%, and 50% of the second 3%, of each participant's
compensation that is contributed to the 401(k) Plan either on a pre-tax or
after-tax basis. In addition, the Company, in it discretion, may make profit-
sharing contributions each year in cash or Common Stock of the Company. Any
profit-sharing contributions made by the Company will be allocated to each
participant's account under the 401(k) Plan in a proportionate amount based on
the participant's compensation for the year in relation to all participants'
compensation for the year. All Company and employee contributions to the
401(k) Plan are allocated to a participant's individual account.
 
  All Company and employee contributions to the 401(k) Plan plus the earnings
thereon are 100% vested. Employees may direct the investment of their accounts
to various investment funds. The 401(k) Plan provides for hardship withdrawals
and loans to participants. The trustee of the 401(k) Plan is Vanguard
Fiduciary Trust Company.
 
INSURANCE AND INDEMNIFICATION
 
  Prior to the Separation, the Company intends to obtain directors' and
officers' insurance against certain liabilities such persons may incur on
behalf of the Company. For a discussion of the limitations on liability of the
Company's directors and the indemnification by the Company of such directors
set forth in the Company's bylaws , see "Description of Capital Stock--
Limitation on Liability and Indemnification."
 
EMPLOYMENT AGREEMENTS
   
  Prior to consummation of the Offering, the Company expects to enter into
employment agreements with Ronald L. King, Michael J. Hughes and each of the
executive officers of the Company. The agreement with Mr. King provides that
Mr. King will serve as the President and Chief Executive Officer of the
Company for a period of three years after the date of the agreement. Under the
agreement, the Company or Mr. King may terminate Mr. King's employment with or
without cause. If Mr. King's employment is terminated by the Company without
cause, the Company must continue to pay Mr. King's salary at the time of
termination for the remainder of the term of the agreement. Mr. King is
subject to a non-competition covenant during the term of the agreement and for
a one-year period following the earlier of his termination of employment or
expiration of the agreement. The agreements with the executive officers of the
Company are similar to the agreement with Mr. King, except that the term of
each such agreement is one year. Mr. Hughes will have an agreement which
protects him in the event of a change of control.

                            PRINCIPAL SHAREHOLDERS
 
  As of the date of this Prospectus, all of the Company's capital stock is
owned by Irex. Immediately following the Separation and the Offering, all of
the Company's capital stock will be owned by the shareholders of Irex who
receive shares of Common Stock in the Separation and by new shareholders who
purchase Common Stock in the Offering. See "Separation from Irex." The
following table sets forth certain information known to the Company regarding
the beneficial ownership of the Company's Common Stock immediately following
consummation of the Separation and the Offering with respect to (i) each
person who the Company expects will become the beneficial owner of more than
5% of the outstanding Common Stock, (ii) each director and named executive
officer of the Company and (iii) all directors and executive officers of the
Company as a group. Unless otherwise specified, each person set forth below
has sole voting and investment power with respect to the shares reported.

                             SEPARATION FROM IREX
 
BACKGROUND AND REASONS FOR THE SEPARATION
   
  Since commencing operations in 1982, the Company has been a wholly owned
subsidiary of Irex. Through its operating subsidiaries other than the Company,
Irex is primarily engaged in the business of specialty contracting throughout
the United States and Canada. In January 1998 Irex announced plans to effect
the Separation through a pro rata distribution of 100% of the capital stock of
the Company to the shareholders of Irex. The Separation will occur immediately
prior to the consummation of the Offering, and the Offering is conditioned
upon the consummation of the Separation. Immediately following the Separation
and the Offering, all of the capital stock of the Company will be owned by the
shareholders of Irex who receive shares of Common Stock in the Separation and
by new shareholders who purchase Common Stock in the Offering.     
 
  The decision to effect the Separation is based on a number of factors. The
Separation will provide both corporations with greater managerial, operational
and financial flexibility to focus on and respond to changing market
conditions in their respective business environments. The Company also
believes that its ability to pursue and finance acquisitions and other
business opportunities will be enhanced if the Company operates independently.
The Separation will provide the Company with direct access to capital markets,
subject to certain limitations for a two-year period following the Separation.
See "Risk Factors--Limitations on Ability to Raise Equity Capital and
Dependence on Alternative Financing." As a separate entity, the Company will
not be subject to Irex's capital structure restrictions and will be in a
better position to fund its operating and growth strategies. Furthermore,
financial advisors have advised Irex and the Company that equity capital
necessary to meet the business needs of Irex and the Company can be most
effectively raised through an initial public offering of the stock of the
Company following its Separation from Irex, rather than through a stock
offering by either Irex or the Company while Irex continues to hold a
substantial equity interest in the Company. In addition, management believes
the Separation will assist the Company in serving certain customers. Through
the specialty contracting businesses operated by its other subsidiaries, Irex
competes with customers whose business is solicited by the Company, and the
Company believes these customers will be more likely to purchase products from
the Company after it is independent from Irex. The Separation will also enable
the Company to provide its management and employees with incentive
compensation in the form of direct and indirect equity ownership in the
Company.
   
  Immediately prior to consummation of the Separation, the Company will
declare a dividend to Irex in the amount of $10.5 million. This amount
corresponds to $10.5 million of outstanding Preferred Stock of Irex which will
remain Irex's obligation following the Separation. The Company has not had and
will not have any obligations or liabilities under the Preferred Stock
following the Separation. The Company will pay the dividend by executing a
note to Irex and the resulting indebtedness will be repaid with a portion of
the proceeds of the Offering. See "Use of Proceeds." In connection with the
Separation and the Offering, the Company will also pay approximately $9.1
million of debt owed by the Company to an affiliate which will be paid with
proceeds from the Offering, and approximately $17.8 million owed to Irex
pursuant to an intercompany account which the Company intends to pay with
borrowed funds from a credit facility.     
 
  Another subsidiary of Irex, ACandS, Inc. ("ACandS"), is engaged in the
thermal insulation contracting business. ACandS has been the subject of
numerous lawsuits seeking damages for injuries allegedly caused by exposure to
asbestos contained in insulation products installed or sold by ACandS before
1974. The Company
 
                                      41
<PAGE>
 
has never been named as a defendant in any asbestos-related lawsuit, nor has
any asbestos-related claim been made against it. The Company's involvement
with the thermal insulation contracting business has been minimal, and, in the
Company's opinion, it has no material liability in connection with that
involvement. The Company believes that adequate insurance coverage is
available to ACandS and its affiliated companies, including the Company, for
asbestos-related suits.
 
AGREEMENTS WITH IREX
 
  In connection with the Separation and the Offering, the Company will enter
into several agreements with Irex and its subsidiaries setting forth certain
interim and longer-term relationships between the companies. The following
summaries of the principal terms of these agreements are qualified in their
entirety by reference to the full text of such agreements. See "Additional
Information."
   
  Corporate Separation Agreement. Prior to the consummation of the Separation
and the Offering, the Company and Irex and its subsidiaries (collectively, the
"Irex Companies") will enter into a separation agreement (the "Separation
Agreement") which sets forth certain agreements with respect to the Separation
and certain agreements between the Company and the Irex Companies governing
the relationship between them following the Separation and the Offering.
Pursuant to the Separation Agreement, Irex will provide the Company with
access to Irex's management information systems for a three-year period
following consummation of the Offering. Under the agreement, access to system
hardware and software and related support services maintained by Irex will be
made available on a quarterly fee basis based on a formula that takes into
account the Company's relative use of the system. The agreement also provides
for the Company to utilize customization capabilities of system programmers
employed by Irex on an hourly fee basis. The Separation Agreement also
provides reciprocal indemnification provisions between the Irex Companies and
the Company, pursuant to which the Irex Companies agree to indemnify the
Company for liabilities relating to their businesses arising at any time, and
the Company agrees to indemnify the Irex Companies for liabilities relating to
its business arising after December 23, 1981. The agreement also includes
provisions governing certain workers' compensation and liability insurance
payments, pursuant to which Irex will maintain responsibility for processing
payment claims occurring as a result of incidents involving the Company's
employees and arising prior to the date of the Separation, and the Company
will indemnify Irex for payments made by Irex as a result of such claims (up
to the amount of the deductible stated in the workers' compensation insurance
policies governing such claims). The agreement also provides for the Company
to reimburse Irex for all third-party expenses incurred in connection with the
Separation and Offering, including attorneys' and accountants' fees and
expenses, filing fees, listing fees, printing costs and similar items.
Pursuant to the Separation Agreement, intercompany accounts among Irex, Irex
affiliates and the Company will be settled as of the date of consummation of
the Separation. As of March 31, 1998, the settlement of those accounts would
result in a payment of $21.5 million from the Company to Irex.     
   
  Tax Sharing and Indemnification Agreement. Prior to the consummation of the
Separation, the Company and Irex will enter into a tax sharing and
indemnification agreement (the "Tax Agreement"). Pursuant to the Tax
Agreement, (i) the Company will generally be indemnified for tax liabilities
of any consolidated, combined and unitary group of corporations that includes
Irex and/or its subsidiaries (including the Company) (an "Irex Group") for
periods prior to the consummation of the Separation other than specified tax
liabilities attributable to the income or operations of the Company, (ii) the
Company will indemnify Irex and its subsidiaries for any other specified tax
liabilities of the Irex Group or the Company related to the Company for
periods prior to the consummation of the Separation, (iii) the Company will be
restricted, for a period of two years following the date of the consummation
of the Separation, from engaging in certain transactions (certain issuances of
stock, redemptions of stock or ceasing to engage in its trade or business)
without first obtaining either a ruling from the Internal Revenue Service or
an opinion from nationally recognized tax counsel that the transaction will
not affect the tax-free nature of the Separation to Irex or its shareholders
and (iv) the Company will be required to indemnify Irex and its shareholders
for tax liabilities that may be incurred by Irex or its shareholders as a
result of actions that the Company may undertake following the Separation and
that cause the Separation to be treated as a taxable transaction to Irex or
its shareholders. The Company does not expect these restrictions to materially
inhibit its operations or growth opportunities.     
 
 
                                      42
<PAGE>
 
  Irex and the Company will receive an opinion of Dechert Price & Rhoads,
counsel to Irex and the Company, that for U.S. federal income tax purposes the
Separation should qualify as a tax-free spin-off. The opinion of counsel will
be based on certain assumptions and the accuracy of factual representations
made by Irex and the Company. Neither Irex nor the Company is aware of any
present facts or circumstances which should cause such representations and
assumptions to be untrue. However, the opinion of counsel is not binding on
either the Internal Revenue Service ("IRS") or the courts. A ruling has not
been, and will not be, sought from the IRS with respect to the U.S. federal
income tax consequences of the Separation, and it is possible that the IRS may
take the position that the Separation does not qualify as a tax-free spin-off.
See "Risk Factors--Potential Liability for Taxes Related to the Separation."
   
  Benefits Sharing Agreement. Prior to the consummation of the Separation, the
Company and Irex will enter into a benefits sharing agreement (the "Benefits
Agreement") to set forth the manner in which assets and liabilities under
employee benefit plans and other employment-related liabilities will be
divided between them. In general, the Company will be responsible for
compensation and employee benefits relating to both its active and former
employees. Irex will generally remain responsible for compensation and
employee benefits relating to its active and former employees. The Company's
401(k) Plan will receive a transfer of plan assets from the Irex Employees'
Savings Incentive Plan equal to the account balances of the Company's active
and former employees. See "Management--401(k) Plan." Prior to the Separation,
Irex will amend its pension plan to cease future benefit accruals. In
connection with the Separation, the Company may make a payment to Irex for a
portion of the unfunded accrued liability under the Irex pension plan
attributable to the Company's employees and former employees. The Company does
not currently intend to sponsor a pension plan for periods immediately
following the Separation.     
       
                         DESCRIPTION OF CAPITAL STOCK
 
  The following description of the capital stock of the Company is subject to
and qualified in its entirety by reference to the Company's Restated Articles
of Incorporation, which have been filed as an exhibit to the Registration
Statement which includes this Prospectus.
   
  As of the date of this Prospectus, after giving effect to the stock split
effected in connection with the Separation and the Offering, there are
2,913,547 shares of Common Stock issued and outstanding, all of which are held
of record by Irex and all of which will be distributed to the shareholders of
Irex common stock in the Separation. No shares of Preferred Stock are issued
or outstanding.     
 
COMMON STOCK
 
  The Company is authorized to issue up to 15 million shares of Common Stock,
par value $.01 per share ("Common Stock").
   
  The holders of Common Stock are entitled to one vote per share on all
matters to be voted upon by shareholders. Shareholders do not have cumulative
voting rights in the election of directors, meaning that the holders of a
majority of the shares entitled to vote in any election of directors may elect
all of the directors standing for election. Shareholders do not have the
preemptive right to purchase newly issued Common Stock before it is offered to
others by the Company. The bylaws provide that special meetings of the
shareholders of the Company may be called only by the Board of Directors.
Generally, whenever any corporate action is to be taken by vote of the
shareholders of the Company, or by vote of a class of such shareholders of the
Company, it shall be authorized upon receiving the affirmative vote of a
majority of the votes cast by such shareholders, or by such class of
shareholders, entitled to vote thereon.     
 
PREFERRED STOCK
 
  The Company is authorized to issue up to 15 million shares of Preferred
Stock. The Board of Directors is authorized, subject to any limitations
prescribed by law, without further shareholder approval, to issue such
 
                                      43
<PAGE>
 
shares of Preferred Stock in one or more series, with such rights,
preferences, privileges and restrictions, including voting rights, dividend
rights, conversion rights, redemption privileges and liquidation preferences,
as shall be established by the Board of Directors at the time of issuance.
 
  The issuance of Preferred Stock by the Board of Directors could adversely
affect the rights of holders of Common Stock. The issuance of shares of
Preferred Stock could result in securities outstanding that would have
preference over the Common Stock with respect to dividends and in liquidation
and that could (upon conversion or otherwise) enjoy all of the rights of the
Common Stock.
 
  The authority possessed by the Board of Directors to issue Preferred Stock
could potentially be used to discourage attempts by third persons to obtain
control of the Company through merger, tender offer, proxy or consent
solicitation or otherwise, by making such attempts more difficult to achieve
or more costly. The Board of Directors may issue Preferred Stock without
shareholder approval and with voting rights that could adversely affect the
voting power of holders of Common Stock. There are no agreements or
understandings for the issuance of Preferred Stock, and the Company has no
plans to issue any shares of Preferred Stock. See "Risk Factors--Anti-Takeover
Provisions."
 
CERTAIN PROVISIONS OF THE PENNSYLVANIA BUSINESS CORPORATION LAW
 
  The Company is governed by Subchapter F of Chapter 25 of the PBCL. The
Company's restated articles of incorporation provide that the Company shall
not be governed by Subchapters E, G and H of Chapter 25 of the PBCL.
Subchapter F may have an anti-takeover effect and may delay, defer or prevent
a tender offer or takeover attempt that a shareholder might consider in his or
her best interest, including those attempts that might result in a premium
over the market price for the shares held by shareholders. In general,
Subchapter F delays for five years and imposes conditions upon "business
combinations" between an "interested shareholder" and the Company, unless
prior approval of the Board of Directors is given. The term "business
combination" is defined broadly to include various merger, consolidation,
division, exchange or sale transactions, including transactions utilizing the
Company's assets for purchase price amortization or refinancing purposes. An
"interested shareholder," in general, would be a beneficial owner of shares
entitling that person to cast at least 20% of the votes that all shareholders
would be entitled to cast in an election of directors of the Company. The
Company is also governed by other provisions of the PBCL which are designed to
support the validity of actions taken by the Board of Directors in response to
takeover bids, including specifically the board's authority to "accept, reject
or take no action" with respect to a takeover bid, and permitting the
unfavorable disparate treatment of a takeover bidder. Another provision of the
PBCL gives the directors broad discretion in considering the best interests of
the Company, including a provision which permits the board, in taking any
action, to consider various corporate interests, including employees,
suppliers, clients and communities in which the corporation is located, the
short and long-term interests of the corporation and the resources, intent and
conduct of any person seeking to acquire control of the corporation. These
provisions may have the effect of making more difficult and thereby
discouraging attempts to acquire control of the Company in a transaction that
the board or directors determines not to be in the best interests of the
Company.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
  As permitted by the PBCL, the Company's bylaws provide that a director shall
not be personally liable for monetary damages for any action taken, or any
failure to take any action, unless (i) the director has breached or failed to
perform the duties of his office under Section 8363 of the Pennsylvania
Directors Liability Act (relating to standard of care and justifiable
reliance) and (ii) the breach or failure to perform constitutes improper self-
dealing, willful misconduct or recklessness. Such limitation on liability does
not apply to the responsibility or liability of a director pursuant to any
criminal statute or the liability of a director for the payment of taxes
pursuant to local, state or federal law. In addition, the bylaws provide that
the Company shall indemnify any person who is a party or is threatened to be
made a party to any lawsuit or claim for damages arising by reason of the fact
that he is or was a director, officer or employee of the Company or any
subsidiary.

TRANSFER AGENT AND REGISTRAR
   
  The transfer agent and registrar for the Common Stock is Chase Mellon
Shareholder Services.     
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this Offering, there has been no public market for the Common
Stock. No predictions can be made with respect to the effect, if any, that
public sales of shares of the Common Stock or the availability of shares for
sale will have on the market price of the Common Stock after this Offering.
Sales of substantial amounts of the Common Stock in the public market
following this Offering, or the perception that sales may occur, could
adversely affect the market price of the Common Stock or the ability of the
Company to raise capital through a sale of its equity securities.
   
  Upon completion of the Separation and the Offering, 4,913,547 shares of
Common Stock will be outstanding (5,213,547 shares will be outstanding if the
Underwriters' over-allotment option is exercised in full). The 2,000,000
shares of Common Stock sold in the Offering (2,300,000 shares if the
Underwriters' over-allotment option is exercised in full) will be freely
tradable without restriction or further registration under the Securities Act,
unless acquired by an "affiliate" of the Company. An "affiliate" is defined in
Rule 144 promulgated by the Commission under the Securities Act ("Rule 144")
generally as a person who by equity ownership or otherwise controls, is
controlled by or is under common control with the Company. The 2,913,547
shares of Common Stock distributed to shareholders of Irex in the Separation
will be freely tradable following the Separation and Offering, except for
719,483 such shares distributed to affiliates of the Company, which shares
will be subject to (i) lock-up agreements entered into in connection with the
Separation (see below) and (ii) Rule 144, except for the holding period
requirement of Rule 144(d), absent registration or another appropriate
exemption under the Securities Act.     
 
  In general, Rule 144 will permit an affiliate or a person who has held
restricted shares for more than one year to sell within any three-month period
a number of shares that does not exceed the greater of 1% of the then-
outstanding shares of Common Stock or the average weekly trading volume of
such stock during the four calendar weeks preceding such sale, provided that
the Company has either filed certain periodic reports with the Commission or
made publicly available certain information concerning itself and provided
that such sales are made in normal "brokers' transactions" or in transactions
directly with a "market maker" without the solicitation of buy orders by the
brokers or such affiliates. A person who is deemed not to be an affiliate of
the Company at any time during the three months preceding a sale and who has
held restricted shares for more than two years may sell such shares under Rule
144 without regard to the volume limitations described above.
   
  The Common Stock has been approved for inclusion on the Nasdaq National
Market under the symbol "SPIE." Sales of substantial amounts of Common Stock
in the public market, including sales under Rule 144, could have a depressing
effect on the price of the Common Stock.     
 
LOCK-UP AGREEMENTS
   
  In connection with the Separation, certain shareholders will agree, subject
to certain exceptions, not to register for sale or offer, sell or transfer any
shares of Common Stock for a period of two years following consummation of the
Separation. These agreements will cover shares of Common Stock received by
such shareholders in the Separation. In addition, in connection with the
Offering, certain shareholders will agree, subject to certain exceptions, not
to register for sale or offer, sell or transfer any shares of Common Stock for
a period of 180 days after the date of this Prospectus without the prior
written consent of Legg Mason Wood Walker, Incorporated. These agreements will
cover all of the 719,483 shares of Common Stock held by such shareholders. See
"Separation from Irex" and "Underwriting."

                                 UNDERWRITING
 
  The underwriters named below (the "Underwriters"), acting through their
representatives, Legg Mason Wood Walker, Incorporated and Advest, Inc. (the
"Representatives") expect to severally agree, subject to the terms and
conditions of the Underwriting Agreement, to purchase a total of 2,000,000
shares of Common Stock from the Company. The number of shares of Common Stock
that each Underwriter has agreed to purchase is set forth opposite its name
below. The Underwriters are committed to purchase all of such shares if any
are purchased. Under certain circumstances the commitments of non-defaulting
Underwriters may be increased. The names of the several Underwriters and the
respective number of shares to be purchased by each of them are as follows:

</TABLE>
 
  The Underwriters propose to offer the shares of Common Stock to the public
initially at the offering price per share set forth on the cover page of this
Prospectus and to certain dealers at such price less a concession not in
excess of $    per share, and the Underwriters may allow, and such dealers may
reallow, a concession not in excess of $    per share on sales to other
dealers. After the commencement of the public offering of the shares of Common
Stock, the offering price and concession may be changed. The Company has
agreed to indemnify the several Underwriters against certain liabilities which
may be incurred in connection with the Offering, including liabilities under
the Securities Act.
 
  The Company has granted an option to the Underwriters, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to an
aggregate of 300,000 shares of Common Stock from the Company at the same price
per share as the public offering price. The Underwriters may exercise such
option only to cover over-allotments in the sale of the shares of Common Stock
that the Underwriters have agreed to purchase. To the extent the Underwriters
exercise this option, each of the Underwriters has a firm commitment, subject
to certain conditions, to purchase the same percentage of the option shares as
the number of shares to be purchased and offered by that Underwriter as shown
in the above table bears to the 2,000,000 shares of Common Stock initially
offered hereby.
 
  All of the directors and executive officers of the Company expect to agree
with the Representatives not to sell or dispose of any shares owned by them
without the consent of the Representatives for a period of 180 days after the
date of this Prospectus. See "Shares Eligible for Future Sale."
 
  In connection with this Offering, certain Underwriters may engage in passive
market making transactions in the Common Stock in accordance with Regulation M
under the Securities Exchange Act of 1934, as amended, during the two business
day period before the commencement of offers of sales of the Common Stock.
Passive market makers must comply with applicable volume and price limitations
and must be identified as such. In general, a passive market maker must
display its bid at a price not in excess of the highest independent bid for
such security; if all independent bids are lowered below the passive market
maker's bid, however, such bid must then be lowered when certain purchase
limits are exceeded.
 
  Until the distribution of the Common Stock is completed, rules of the
Commission may limit the ability of the Underwriters to bid for and purchase
the Common Stock. As an exception to these rules, the Representatives
 
                                      46
<PAGE>
 
are permitted to engage in certain transactions that stabilize the price of
the Common Stock. Such transactions may consist of bids or purchases for the
purpose of pegging, fixing or maintaining the price of the Common Stock.
 
  If Underwriters create a short position in the Common Stock in connection
with the offering thereof (i.e., if they sell more shares of Common Stock than
are set forth on the cover page of the Prospectus), the Representatives may
reduce that short position by purchasing Common Stock in the open market. The
Representatives also may elect to reduce any short position by exercising all
or part of the over-allotment option described in the Prospectus.
 
  The Representatives also may impose a penalty bid on certain Underwriters.
This means that if the Representatives purchase Common Stock in the open
market to reduce the Underwriters' short position or to stabilize the price of
the Common Stock, they may reclaim the amount of the selling concession from
the Underwriters who sold those shares as part of this Offering.
 
  In general, purchases of Common Stock for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the Common Stock to
be higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid might have an effect on the price of the Common
Stock to the extent that it were to discourage resales of the Common Stock by
purchasers in this Offering.
 
  Neither the Company nor the Underwriters make any representation or
prediction as to the direction or magnitude of any effect that the
transactions described above may have on the price of the Common Stock. In
addition, neither the Company nor the Underwriters make any representation
that the Representatives will engage in such transactions or that such
transactions, once commenced, will not be discontinued without notice.
 
                                 LEGAL MATTERS
 
  The validity of the issuance of the shares of Common Stock offered hereby
will be passed upon for the Company by Dechert Price & Rhoads, Philadelphia,
Pennsylvania. Certain matters in connection with this Offering will be passed
upon for the Underwriters by Stradley, Ronon, Stevens & Young, LLP,
Philadelphia, Pennsylvania.

  After the stock split-up effected in the form of a dividend discussed in
Note 11 to the Company's consolidated financial statements is effected, we
expect to be in a position to render the following audit report.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Specialty Products & Insulation Co.:
   
  We have audited the accompanying consolidated balance sheets of Specialty
Products & Insulation Co. (a Pennsylvania corporation and a wholly owned
subsidiary of Irex Corporation) and subsidiary as of December 31, 1997 and
1996, and the related consolidated statements of income, shareholder's equity
and cash flows for each of the three years in the period ended December 31,
1997. These financial statements and the schedule referred to below are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements and schedule based on our audits.
    
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as, evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Specialty Products &
Insulation Co. and subsidiary as of December 31, 1997 and 1996, and the
results of their operations and their cash flows for each of the three years
in the period ended December 31, 1997, in conformity with generally accepted
accounting principles.
 
  Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule of valuation and
qualifying accounts is presented for purposes of complying with the Securities
and Exchange Commission rules and is not part of the basic financial
statements. This schedule has been subjected to the auditing procedures
applied in the audits of the basic financial statements and, in our opinion,
fairly states in all material respects the financial data required to be set
forth therein in relation to the basic financial statements taken as a whole.

              SPECIALTY PRODUCTS & INSULATION CO. AND SUBSIDIARY
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1997
   
1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION:     
   
Description of Business     
 
  Specialty Products & Insulation Co. and subsidiary (the Company), a wholly-
owned subsidiary of Irex Corporation (Irex) (See Note 11), is a distribution
and fabrication business that competes in the large and highly fragmented
building products industry. The Company broadly defines its two core markets
as mechanical insulation, consisting of pipe, duct, and equipment insulation
for commercial and industrial customers, and architectural/acoustical
products, consisting primarily of acoustical ceilings, fiberglass reinforced
panel, and other wall and ceiling products.
   
Basis of Presentation     
   
  The consolidated financial statements reflect the results of operations,
financial position, changes in shareholder's equity and cash flows of the
Company. The consolidated financial statements have been prepared using the
historical basis in the assets and liabilities and historical results of
operations of the Company.     
   
  The Company receives certain administrative services provided by Irex. The
cost of these services has been allocated to the Company based on the
estimated utilization of those services. In addition, those services not
allocated based on utilization are charged to the Company and its affiliates
through a management fee. These services are discussed further in Note 10.
    
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
Principles of Consolidation
 
  The consolidated financial statements include the accounts of Specialty
Products & Insulation Co. and its wholly-owned subsidiary. All significant
intercompany accounts and transactions have been eliminated in consolidation.
 
Estimates and Assumptions
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of sales and expenses during the reporting
period. Actual results could differ from those estimates.
 
Cash and Cash Equivalents
 
  The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
Inventories
 
  Inventories are stated at the lower of cost or market. Cost is determined
principally on a first-in, first-out (FIFO) basis. Included in inventory cost
are material costs and costs directly associated with the fabrication of the
Company's products.
 
Reserves for Certain Self-Insured Business Risks
 
  The Company is self-insured against a portion of its workers' compensation
and other insurance risks. The process of determining reserve requirements for
losses within its self-insured retention limits utilizes historical trends,
involves an evaluation of claim frequency, severity and other factors and also
includes the effect of future inflation.
 
                                      F-7
<PAGE>
 
Income Taxes
 
  The Company accounts for income taxes using the liability method, whereby
deferred tax assets and liabilities are recognized using enacted tax rates,
for the estimated future tax effects of temporary differences between the
financial reporting and tax bases of assets and liabilities.
 
Property and Equipment
 
  Property and equipment are depreciated using principally the straight-line
method over the following estimated useful lives of the assets. Expenditures
for maintenance and repairs are expensed as incurred.

       <S>                                                <C>
       Buildings.........................................     15 to 30 years
       Leasehold improvements............................      3 to 10 years
       Machinery and equipment...........................       3 to 7 years
</TABLE>
 
Other Assets
 
  Other assets consist of goodwill and other intangibles. Goodwill, which
represents the excess of cost over fair value of the net assets of acquired
businesses, is being amortized on a straight-line basis principally over 15
years. The Company develops operating income projections and evaluates the
recoverability and amortization period of goodwill using these projections.
Based upon management's current assessment, the estimated remaining
amortization period of goodwill is appropriate and the remaining balance is
fully recoverable. There was no unamortized goodwill at December 31, 1996. At
December 31, 1997, unamortized goodwill was $842,000.
 
Revenue Recognition
 
  Sales are recorded as orders are shipped or picked up by the customer and
are reported net of discounts and returns.
 
Supplemental Cash Flow Information
 
  The Company's state income tax payments, net of refunds, were $28,000,
$131,000 and $280,000 in 1995, 1996 and 1997, respectively. Interest on the
notes payable to affiliate and the payable to affiliates account are charged
to the payable to affiliates account.
 
Concentration of Credit Risk and Business
 
  The Company is primarily engaged in the distribution of mechanical
insulational and architectural/acoustical products throughout the United
States.
 
  The Company grants credit to customers after a thorough review of their
financial condition. The concentration of credit risk with respect to accounts
receivable is limited due to the Company's large customer base located
throughout the United States. For the years ended December 31, 1995, 1996, and
1997, no one customer accounted for more than 10% of sales.
 
  The Company purchases materials for resale from a limited number of major
suppliers. Such concentration is normal for the industry and does not
represent an unreasonable risk or vulnerability to the Company.
 
3. ACQUISITIONS:
 
  On October 17, 1997, the Company acquired all of the issued and outstanding
stock of Richlar Industries, Inc. (Richlar), located in East Syracuse, New
York, for cash consideration of approximately $866,000. Richlar is primarily
engaged in the business of precision die cutting, lamination, and specialty
fabrication.
 
  On December 8, 1997, the Company acquired certain assets of Construction
Systems, Inc. (CSI), located in Houston, Texas, for cash consideration of
approximately $2,374,000. CSI was primarily engaged in the distribution of
architectural/acoustical products and specialty products from two distribution
centers in Houston, Texas.
 
  On December 24, 1997, the Company acquired certain assets of the Louisville,
Kentucky distribution center of R. E. Kramig and Company, Inc. (Kramig) for
cash consideration of approximately $213,000. Kramig was primarily engaged in
the distribution of mechanical insulation.
 
                                      F-8
<PAGE>
 
  The acquisitions were accounted for using the purchase method of accounting,
and the financial statements reflect the results of operations and cash flows
of the operation from the dates of the acquisitions. Had the acquisitions
occurred at the beginning of the periods presented, sales and net income would
not have been materially different from reported results.
 
  In January 1995, the Company acquired from Distribution International (DI),
the assets of four distribution centers in North Carolina and Tennessee for
cash consideration of approximately $961,000. DI was primarily engaged in the

4. INCOME TAXES:
 
  The Company's tax return is included in the consolidated federal income tax
returns of Irex. The current and deferred tax expense recorded by the Company
is based on what such amounts would have been had it filed a separate tax
return. All federal income tax payments are made by Irex.
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS
109). Deferred income taxes are computed based on the differences between
financial reporting and income tax reporting bases of assets and liabilities
using enacted tax rates. The impact of changes in tax rates is reflected in
income in the period in which the change is enacted. In conformity with SFAS
109, deferred tax assets are classified based on the financial reporting
classification of the related liabilities and assets which give rise to
temporary book/tax differences. Deferred taxes relate to the following
temporary differences:

  The Company has determined that no valuation allowance for the deferred tax
asset is required as of December 31, 1996 and 1997 as it is considered more
likely than not that such benefits will be realized in the future through the
combination of carryback availability, certain tax planning strategies that
would allow for acceleration of deductible temporary differences to utilize
remaining carryback availability and through expected future taxable income.

5. EMPLOYEE BENEFIT PLANS:
 
 Pension Plans
 
  The Company's salaried employees participate in Irex's noncontributory
defined benefit pension plan. The benefits under the plan are based on years
of service and salary levels. Irex's policy is to fund pension costs in
accordance with the requirements of the Employee Retirement Income Security
Act of 1974. The Company receives an allocation of the plan's expenses from
Irex. In 1995, 1996, and 1997, the Company's share of the plan's total expense
was $230,000, $245,000, and $165,000, respectively. The Company will not
participate in the plan following its separation from Irex. All liabilities
associated with the plan will remain with Irex. The following table sets forth
the Plan's funded status and related amounts recognized in the consolidated
balance sheet of Irex and subsidiaries at December 31, 1996 and 1997:

</TABLE>
 
  The Company also maintains a defined contribution plan for its hourly-paid
employees. Company contributions to the plan are based on a percentage of
eligible employees' compensation. The expense for this plan was $69,000 in
1995, $108,000 in 1996, and $105,000 in 1997.
 
 Postretirement Benefits Other Than Pensions
 
  In addition to the pension plans, the Company's retired employees
participate in an Irex-sponsored plan that provides certain health care
benefits. Active salaried employees who were at least age 55 and had 10 years
of consecutive service at January 1, 1990, are eligible for these benefits
upon retirement. Also, active salaried
 
                                     F-10
<PAGE>
 
employees of the Company whose age plus years of service equaled at least 55
at January 1, 1990, are eligible for these benefits upon retirement when they
attain age 62 as long as such employees have either 20 years of service or
their age plus years of service equals 90 upon retirement. Cash payments of up
to $60 per month are given to retirees over age 65 to purchase supplemental
Medicare coverage. Eligible retirees under age 65 are fully covered by Irex's
insurance plan. The number of retirees under age 65 currently participating in
the plan is not significant. Also the number of active employees of the
Company who may become eligible is not significant; further, the Company will
not participate in the plan following its separation from Irex. All
liabilities associated with the plan will remain with Irex.
 
  The expected cost of these benefits is charged to expense during the years
that the employees render service. The transition obligation is being
amortized over 20 years. In 1995, 1996, and 1997 the Company's share of the
Plan's total expense was $22,000, $29,000, and $15,000, respectively.
 
  The following table sets forth the plan's funded status and amounts
recognized in the consolidated balance sheet of Irex and subsidiaries at
December 31, 1996 and 1997:

</TABLE>
 
  For measurement purposes, a 13% annual rate of increase in the per capita
cost of covered health care benefits was assumed for calendar 1997; the rate
was assumed to decrease to 10% in 1998 and 7% for 2001 and remain level
thereafter. Due to the provisions of the plan, increasing the assumed health
care cost trend rates by one percentage point in each year would not have a
significant impact on the accumulated postretirement benefit obligation or the
aggregate of the service and interest cost components of net periodic
postretirement benefit cost for 1997.
 
  The weighted-average discount rate used in determining the accumulated
postretirement benefit obligation was 7.75% and 7.25% at December 31, 1996 and
1997, respectively. The expected long-term rate of return on assets was 8.50%
at December 31, 1996.
 
 Other
 
  The Company has an incentive compensation plan covering substantially all of
its officers and key employees. The amount of incentive compensation is
dependent upon the rate of return on assets of the Company and the particular
regional or branch office. Total incentive compensation expense was $1,012,000
for 1995, $1,335,000 for 1996, and $1,428,000 for 1997.
 
  Substantially all of the Company's salaried employees are covered by defined
contribution savings incentive and employee stock ownership plans (ESOP)
maintained by Irex. Contributions to the savings incentive plan are based on a
percentage of employee contributions to the plan, while ESOP contributions are
discretionary. The Company's share of these plans' total expense was $256,000
in 1995, $299,000 in 1996, and $259,000 in 1997.

6. INCOME PER COMMON SHARE:
 
  In 1997, the Company adopted Statement of Financial Accounting Standards
(SFAS) No. 128 "Earnings Per Share." SFAS No. 128 requires dual presentation
of basic and diluted earnings per share on the face of the income statement
for all entities with complex capital structures. The Company's basic income
per share is calculated as income available to shareholders divided by the
weighted average number of shares outstanding. Earnings per share have been
retroactively restated to reflect the 291.4 to 1 stock split-up effected in
the form of a dividend discussed in Note 11. For diluted income per share,
there are no common stock equivalents.

Such guarantees with respect to the Company will terminate upon completion of
the separation transaction discussed in Note 11.

  At December 31, 1996, an affiliate of the Company maintained the reserves
for workers' compensation, general and auto liability insurance. See note 10.
    
10. RELATED PARTIES:
 
  The Company sells its products to the specialty contracting subsidiaries of
Irex. Sales to those affiliates are included in the Company's net sales as
reflected in the consolidated statements of income. Net sales to the Company's
affiliates were $10,682,000, $12,383,000 and $9,301,000 in 1995, 1996 and
1997, respectively.
   
  Irex provides various administrative services to its affiliates, including
the Company. These services include, among others, management and maintenance
of the information systems, legal, credit and risk management, cash
management, tax, accounting and personnel administration. Irex allocates these
costs to its affiliates primarily based on the estimated utilization of the
services. Irex also charges a management fee to each of its affiliates,
including the Company, to distribute costs that are not allocated based on
utilization. The management fee is calculated as a percentage of net sales and
charged to each affiliate accordingly. Collectively, the allocation of
administrative expenses and management fee are reflected as selling, general
and administrative expenses in the Company's consolidated statements of
income. Management believes the methodology used to allocate these expenses is
reasonable. The Company was charged $1,616,000, $1,815,000 and $2,542,000 in
1995, 1996 and 1997, respectively. Amounts allocated to the Company by Irex in
excess of the actual costs incurred by Irex for these services are shown in
the statements of shareholder's equity as a distribution to parent.     
   
  Irex administers the Company's insurance program. Prior to 1997, the
reserves for workers' compensation and other insurance risks were not
reflected on the consolidated balance sheet of the Company. As indicated in
note 9 above, an affiliate of the Company maintained these reserves and made
payments on behalf of the Company. The appropriate charges to the Company were
recognized in the payable to affiliates account. The Company's expense related
to workers' compensation and other insurance programs was $484,000 in 1995,
$501,000 in 1996 and $606,000 in 1997.     
 
                                     F-13

  The Company's cash transactions flow through a consolidated banking
arrangement that is maintained by Irex. The Company, in the normal course of
business, receives credit for cash deposited or charges for working capital
needed. The payable to affiliates account, at December 31, 1997, includes the
Company's cumulative cash borrowings from Irex and affiliates. Based upon the
activity within the payable to affiliates account, the Company is charged
interest expense from Irex. Interest expense was $1,048,000 in 1995,
$1,132,000 in 1996 and $1,249,000 in 1997.     
 
11. SUBSEQUENT EVENTS:
 
 Separation
 
  On January 19, 1998, Irex announced its intention to spin off Specialty
Products & Insulation Co. to its shareholders. Irex's Board of Directors, at
its February 26, 1998 meeting, approved the proposed transaction in which
shareholders of Irex Common stock will receive a dividend of the Company's
Common stock. This dividend is expected to be a tax-free distribution to
current shareholders of Irex Common stock. The transaction is expected to be
completed in the second or third quarter of 1998.
 
  Concurrent with the spin off transaction described above, the Company
intends to file a registration statement on Form S-1 with the Securities and
Exchange Commission for purposes of registering shares of common stock.
 
  On April 9, 1998, the Company filed Restated Articles of Incorporation which
increased the authorized number of shares of common stock to 15,000,000,
changed the common stock par value to $0.01 and authorized 15,000,000 shares
of Preferred stock at $0.01 par value. These changes have been retroactively
reflected in the accompanying financial statements.
 
  In conjunction with the above transactions, the Company expects to enter
into several agreements with Irex.
 
  .Corporate Separation Agreement--Pursuant to this agreement, Irex will
  provide management information system services to the Company. These
  services will be provided subject to a quarterly or hourly fee. In
  addition, certain indemnifications, excluding tax related items, between
  the Company and Irex are defined in this agreement.
 
  .Tax Sharing and Indemnification Agreement--Tax related indemnifications
  between the Company and Irex are defined within this agreement. These
  indemnifications relate to the periods before and after the transactions
  described above.
 
  .Benefits Sharing Agreement--This agreement addresses the division of
  employee benefit plans and other employment-related liabilities between the
  Company and Irex.
 
  Prior to the spin-off described above, the Company will declare a 291.4 to 1
stock split up effected in the form of a dividend. The stock split-up has been
retroactively reflected in the accompanying financial statements.
 
 Acquisition
 
  On March 1, 1998, the Company acquired the assets of Extol of Texas, Inc.
(Extol), located in Houston, Texas, for cash consideration of approximately
$5,558,000. Extol is primarily engaged in the distribution and fabrication of
commercial and industrial insulation systems, and other specialty products.
   
12. PRO FORMA INFORMATION (UNAUDITED):     
   
  The unaudited pro forma consolidated balance sheet of the Company as of
December 31, 1997 reflects the planned dividend (estimated at $10,490,000) to
be made to Irex through the execution of a note payable to Irex and
subsequently paid from the net proceeds of the Offering. See "Use of
Proceeds." Pursuant to the requirements of the Securities and Exchange
Commission, the dividend has been reflected in the pro forma balance sheet
without giving effect to any receipt of the net proceeds from the Offering. In
addition, pursuant to the requirements of the Securities and Exchange
Commission, the pro forma income per share data giving effect to the number of
shares whose proceeds were used to in effect pay the dividend on both a basic
and diluted basis is $0.78. Pro forma weighted average shares outstanding on
both a basic and diluted basis was 3,867,184.

              SPECIALTY PRODUCTS & INSULATION CO. AND SUBSIDIARY
              
           NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS     
                                  
                               (UNAUDITED)     
                                 
                              MARCH 31, 1998     
   
1. BASIS OF PRESENTATION:     
     
  Specialty Products & Insulation Co. (the Company) is a wholly owned
  subsidiary of Irex Corporation (Irex). The consolidated financial
  statements of the Company include the accounts of Specialty Products &
  Insulation Co. and its wholly owned subsidiary. All significant
  intercompany accounts and transactions have been eliminated in
  consolidation.     
     
  The condensed consolidated financial statements included herein have been
  prepared by the Company, without audit, pursuant to the rules and
  regulations of the Securities and Exchange Commission. Certain information
  and footnote disclosure normally included in financial statements prepared
  in accordance with generally accepted accounting principles have been
  condensed or omitted pursuant to such rules and regulations. These
  condensed consolidated financial statements should be read in conjunction
  with the Company's annual audited financial statements for the year ended
  December 31, 1997.     
     
  The financial information presented herein reflects all adjustments
  (consisting only of normal recurring adjustments) which are, in the opinion
  of management, necessary for a fair presentation of the results for the
  interim periods presented. The results for interim periods are not
  necessarily indicative of the results to be expected for the full year.
         
2. RELATED PARTIES:     
     
  The Company sells its products to the specialty contracting subsidiaries of
  Irex. Sales to those affiliates are included in the Company's net sales as
  reflected in the consolidated statements of income. Net sales to the
  Company's affiliates were $2,787,000 and $1,940,000, in the three months
  ended March 31, 1997 and 1998, respectively.     
     
  Irex provides various administrative services to its affiliates, including
  the Company. These services include, among others, management and
  maintenance of the information systems, legal, credit and risk management,
  cash management, tax, accounting and personnel administration. Irex
  allocates these costs to its affiliates primarily based on the estimated
  utilization of the services. Irex also charges a management fee to each of
  its affiliates, including the Company, to distribute costs that are not
  allocated based on utilization. The management fee is calculated as a
  percentage of net sales and charged to each affiliate accordingly.
  Collectively, the allocation of administrative expenses and management fee
  are reflected as selling, general and administrative expenses in the
  Company's consolidated statements of income. Management believes the
  methodology used to allocate these expenses is reasonable. The Company was
  charged $618,000 and $627,000 in the three months ended March 31, 1997 and
  1998, respectively. Amounts allocated to the Company by Irex in excess of
  the actual costs incurred by Irex for these services were $86,000 and
  $96,000 for the three months ended March 31, 1997 and 1998, respectively,
  and are considered to be a distribution to parent.     
   
3. SUPPLEMENTAL CASH FLOW INFORMATION:     
     
  The Company's state income tax payments, net of refunds, were $107,000 and
  $99,000 for the first three months of 1997 and 1998, respectively. Interest
  on the notes payable to affiliate and the payable to affiliates account are
  charged to the payable to affiliates account.     
   
4. SEPARATION:     
     
  On January 19, 1998, Irex announced its intention to spin off Specialty
  Products & Insulation Co. to its shareholders. Irex's Board of Directors,
  at its February 26, 1998 meeting approved the proposed transaction     
 
                                     F-18
<PAGE>
 
     
  in which shareholders of Irex common stock will receive a dividend of the
  Company's common stock. This dividend is expected to be a tax-free
  distribution to current shareholders of Irex common stock. The transaction
  is expected to be completed in the second or third quarter of 1998.     
          
  On April 9, 1998, the Company filed Restated Articles of Incorporation,
  which increased the authorized number of common stock to 15,000,000,
  changed the common stock par value to $0.01 and authorized 15,000,000
  shares of preferred stock at $0.01 par value. These changes have been
  retroactively reflected in the accompanying financial statements.     
     
  On April 10, 1998, the Company filed a registration statement with the
  Securities and Exchange Commission relating to the initial public offering
  of 2,000,000 shares of common stock. The spin-off described above will
  occur immediately prior to the initial public offering. Following the spin-
  off and initial public offering, the Company will be an independent
  company.     
     
  Prior to the spin-off described above, the Company will declare a 291.4 to
  1 stock split-up effected in the form of a dividend. The stock split-up has
  been retroactively reflected in the accompanying financial statements.     
   
5. CREDIT FACILITY:     
     
  Subject to completion of the offering and certain other conditions,
  including execution of appropriate loan documentation, the Company executed
  commitment letters related to a credit facility. The credit facility is an
  unsecured line of credit aggregating $30 million with interest rates
  related to short term rates.     
   
6. ACQUISITIONS:     
     
  On March 1, 1998, the Company acquired the assets of Extol of Texas, Inc.
  (Extol), located in Houston, Texas, for cash consideration of approximately
  $5,558,000. Extol is primarily engaged in the distribution and fabrication
  of commercial and industrial insulation systems, and other specialty
  products. The acquisition was accounted for using the purchase method of
  accounting, and the financial statements reflect the results of operations
  and cash flows of the operation from the date of acquisition.     
          
  On May 13, 1998, the Company executed a letter of intent to purchase
  certain assets of a mechanical insulation fabricator with fiscal year 1997
  sales of approximately $4.0 million.     
   
7. PRO FORMA INFORMATION:     
     
  The unaudited pro forma consolidated balance sheet of the Company as of
  March 31, 1998, reflects the planned dividend (estimated at $10,490,000) to
  be made to Irex through the execution of a note payable to Irex and
  subsequently paid from the net proceeds of the initial public offering.
  Pursuant to the requirements of the Securities and Exchange Commission, the
  dividend has been reflected in the pro forma balance sheet without giving
  effect to any receipt of the net proceeds of the initial public offering.
  In addition, pursuant to the requirements of the Securities and Exchange
  Commission, the pro forma income per share data giving effect to the number
  of shares whose proceeds were used to in effect pay the dividend on both a
  basic and diluted basis is $0.13. Pro forma weighted average shares
  outstanding on both a basic and diluted basis are 3,867,184.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Bylaws of the Company provide that the Company shall indemnify any
person who is a party or is threatened to be made a party to any lawsuit or
claim for damages arising by reason of the fact that he is or was a director,
officer or employee of the Company or any subsidiary. The Company intends to
obtain directors' and officers' insurance against certain liabilities such
persons may incur on behalf of the Company.
 
  Pennsylvania law permits the Registrant to provide similar indemnification
to employees and agents who are not directors or officers. The determination
of whether an individual meets the applicable standard of conduct may be made
by the disinterested directors, independent legal counsel or the stockholders.
Pennsylvania law also permits indemnification in connection with a proceeding
brought by or in the right of the Registrant to procure a judgment in its
favor. To the extent that an indemnification for liabilities arising under the
Securities Act is permitted to directors, officers, or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Commission such indemnification is against
public policy as expressed in that Act and is therefore unenforceable.
 
  The Underwriting Agreement provides for indemnification by the Underwriters
of the registrant and its directors, officers and controlling persons for
certain liabilities, including liabilities arising under the Securities Act.

ITEM 17. UNDERTAKINGS.
 
  (a) The undersigned registrant hereby undertakes to provide to the
Underwriters at the closing specified in the Underwriting Agreement,
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.
 
  (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.
 
  (c) The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

     Director.  The Directors shall be classified in respect to the time for

     be originally elected for a term expiring at the annual meeting of
     shareholders to be held in 2000, and another class shall be originally
     elected for a term expiring at the annual meeting of shareholders to be
     held in 2001, with the members of each class to hold office until their
     successors are elected and qualified.  At each succeeding annual meeting of
     the shareholders of the Company, the successors of the class of Directors
     whose term expires at that meeting shall be elected by plurality vote of
     all votes cast at such meeting to hold office for a term expiring at the
     annual meeting of shareholders held in the third year following the year of
     their election.

     (b)  Vacancies.  Vacancies in the Board of Directors, including vacancies
     resulting from an increase in the number of Directors, shall be filled by a
     majority of the Directors then in office, though less than a quorum, and
     each person so elected shall be a Director to serve for the balance of the
     unexpired term and until his successor is duly elected and qualified.

     (c)  Removal. The entire Board of Directors, or any class of the Board, or
     any individual Director may be removed from office by the vote of
     shareholders entitled to

                                       3
<PAGE>
 
     vote thereon only for cause.  The amendment or repeal of this provision
     shall not apply to any incumbent Director during the balance of the term
     for which he was elected.

     (d)  Cumulative Voting. Shareholders shall not have cumulative voting
     rights in the election of Directors.

     (e)  Inapplicability of Certain Directors Fiduciary Duty Provisions. The
     provisions of Section 1715 of the Pennsylvania Business Corporation
     Law shall not be applicable to the Company.

7.   Opt-out.  Subchapters E, G and H of Chapter 25 of the Business Corporation
Law of 1988, as amended, shall not be applicable to the Company.

8.   Amendment. The Company reserves the right, from time to time, to amend,
alter or repeal any provision contained in these Restated Articles of
Incorporation in the manner now or hereafter provided by statute for the
amendment of articles of incorporation.

majority of the whole Board designate one or more committees, each committee to
consist of two or more Directors and such alternate members (also Directors) as
may be designated by the Board. Any such committee, to the extent provided in
such resolution, may exercise the authority of the Board of Directors in the
management of the business and affairs of the Company.

In the absence or disqualification of any member of a committee, the member or
members thereof present at any meeting and not disqualified from voting, whether
or not he or they constitute a quorum, may unanimously appoint another Director
to act at the meeting in the place of any such absent or disqualified member.

2.7. Limitation on Liability.  A Director shall not be personally liable for 
     -----------------------                                     
monetary damages for any action taken, or any failure to take any action unless
(i) the Director has breached or failed to perform the duties of his office
under Sections 1711-1718 of the Pennsylvania Business Corporation (relating to
fiduciary duty) and (ii) the breach or failure to perform constitutes self-
dealing, willful misconduct or recklessness. The provisions of this Section 2.7
shall not apply to (i) the responsibility or liability of a Director pursuant to
any criminal statute or (ii) the liability of a Director for the payment of
taxes pursuant to local, state or federal law. Any repeal or modification of
this Section 2.7 shall be prospective only, and shall not affect, to the
detriment of any Director, any limitation on the personal liability of a
Director of the corporation existing at the time of such repeal or modification.

4.1. Right to Indemnification.  The Company shall indemnify any person who was 
     ------------------------                                  
or is a party, or is threatened to be made a party to any threatened, pending,
or completed action or proceeding, whether civil, criminal, administrative, or

employee of the Company or any subsidiary thereof, or is or was serving at the
request of the Company or any subsidiary thereof as a Director, officer,
employee, or agent of another domestic or foreign corporation for-profit or not-
for-profit, partnership, joint venture, trust or other enterprise, against

Company or any subsidiary, to the extent that the power to indemnify such person
has been or may in the future be granted by statute and that such person is not
insured or otherwise indemnified.

claim for indemnification and such claim, at the option of the person seeking
indemnification, the permissibility of indemnification shall be determined by
independent legal counsel selected jointly by the Company and the person seeking

such person, such obligations of the Company in connection with a claim based on
any act or failure to act occurring before such modification or repeal.

4.5. Indemnification Not Exclusive; Inuring or Benefit.  The indemnification and
     -------------------------------------------------      
advancement of expenses provided by this Article IV shall not be deemed
exclusive of any other right to which one indemnified may be entitled under any

official capacity and as to action in another capacity while holding such
office, and shall inure to the benefit of the heirs, executors and
administrators of any such person.

     ---------------------------------------------

has not been prohibited by applicable law, (ii) create any fund of any nature,
whether or not under the control of a trustee, or otherwise secure any of its
indemnification obligations and (iii) give other indemnification to the extent
not prohibited by law.
