FOR IMMEDIATE RELEASE

                                  NEWS RELEASE

              ASSOCIATED MATERIALS TO ACQUIRE GENTEK HOLDINGS INC.

CUYAHOGA FALLS, Ohio, July 31, 2003 -- Associated Materials Incorporated
("Associated Materials") today announced that it has signed a definitive
agreement to acquire all of the issued and outstanding shares of capital stock
of Gentek Holdings Inc. ("Gentek Holdings") and to repay all indebtedness of
Gentek Holdings and its subsidiaries for an aggregate purchase price of
approximately $118 million in cash, which includes an estimated working capital
adjustment. The purchase price is subject to certain adjustments as well as
customary transaction fees.

Gentek Holdings, which is privately held, is the parent company of Gentek
Building Products, Inc. and Gentek Building Products Limited (collectively,
"Gentek"). Gentek manufactures and distributes vinyl, aluminum and steel siding
and accessories and vinyl windows under the Revere(R) and Gentek(R) brand names.
Gentek markets its products to professional contractors on a wholesale basis
through company-owned distribution centers and independent distributors in the
United States and Canada. For the year ended December 31, 2002, Gentek reported
net sales of $260.1 million, net income of $9.2 million and EBITDA of $19.3
million. A reconciliation of EBITDA to net income is included in the table
below.

Michael Caporale, President and Chief Executive Officer of Associated Materials
commented, "I am very excited about our acquisition of Gentek. Gentek's thirteen
company-owned distribution centers in the mid-Atlantic region of the United
States and twenty company-owned distribution centers in Canada will expand
Associated Materials' market presence throughout North America. Gentek's strong
U.S. independent distributor business will also allow us to increase our
presence in this important market channel. Their outstanding metal manufacturing
capability will allow us to vertically integrate the metals products that are
sold by our Alside supply centers. Finally, Gentek's world class vinyl
manufacturing plant in Burlington, Ontario will provide Associated Materials
with additional vinyl siding capacity."

Mr. Caporale continued, "We strongly believe in the brand equity of the
Revere(R) and Gentek(R) names. We intend to maintain distinct separation of
these brands from our Alside brand by continuing to offer differentiated
product, sales and marketing support. Revere(R) and Gentek(R) customers will
continue to receive the same excellent service and support that they have
enjoyed in the past."

The proposed acquisition is expected to close by the end of August 2003 and is
subject to customary conditions including receipt of regulatory approvals and
Associated Materials' receipt of financing.

In connection with the acquisition, Associated Materials expects to amend its
existing $165 million credit facility by adding a term loan facility to borrow
up to an approximate additional $113.5 million and expanding its revolving loan
facility from $40 million to $70 million, including a new Canadian subfacility
of $15 million (USD). UBS, Credit Suisse First Boston, and CIBC World Markets
have agreed, on an uncommitted basis to arrange the new credit facility on
substantially the same terms and conditions as Associated Materials' existing
credit



facility. Associated Materials' 9 3/4% Senior Subordinated Notes Due 2012 will
continue to remain outstanding.

White & Case LLP served as legal advisor to Associated Materials.

EBITDA                                                           $   19.3

(a)  EBITDA is calculated as net income plus interest, taxes, depreciation and
     amortization. Associated Materials considers EBITDA to be an important
     indicator of Gentek's operational strength and performance of its business.
     Associated Materials has included Gentek's EBITDA because it believes
     EBITDA is used by certain investors as one measure of a company's ability
     to service its debt. EBITDA should be considered in addition to, not as a
     substitute for, Associated Materials' or Gentek's net income or loss or to
     cash flows as well as other measures of financial performance in accordance
     with accounting principles generally accepted in the United States. EBITDA
     has not been prepared in accordance with accounting principles generally
     accepted in the United States. Therefore, EBITDA as presented by Associated
     Materials or Gentek may not be comparable to similarly titled measures
     reported by other companies.
