Ply Gem to Expand Its Windows & Doors Portfolio Through Acquisition of CertainTeed's...

KEARNEY, Mo. -- Ply Gem Industries, Inc. and its private equity sponsor, Caxton-Iseman Capital, Inc., today announced that it has entered into a definitive agreement to acquire CertainTeed Corporation's vinyl window and patio door business in a cash

transaction. CertainTeed's vinyl window business is a leading manufacturer of premium vinyl windows and doors and produces windows for the residential new construction and remodeling markets and produces and sells window lineals to licensed window fabricators in the Eastern United States. The CertainTeed vinyl window and patio door business operates three fabrication facilities which are located in Auburn, WA, Corona, CA, and Sacramento, CA.

The acquisition is expected to be financed through a combination of cash on hand and borrowings against Ply Gem's $75 million revolving credit facility. Completion of the transaction, which is expected to occur in the third quarter of 2007, is subject to customary closing conditions.

Gary E. Robinette, President and Chief Executive Officer of Ply Gem, said, "This acquisition will enable us to capitalize on attractive market opportunities in the West, while strengthening our national presence in the windows and doors market. This transaction will enable Ply Gem to provide our customers with window products for virtually any new construction or home improvement project in any area of the country. CertainTeed Window and Door products are extremely well respected in the marketplace and will complement Ply Gem's existing window and door product offering."

Robert A. Ferris, a Managing Director of Caxton-Iseman Capital, said, "The acquisition of CertainTeed's vinyl window business with its great products and manufacturing footprint in the West presents Ply Gem with exciting new opportunities. Since we acquired Ply Gem in 2004, we have been very pleased by the company's performance and growth trajectory. We continue to be impressed with the quality of the Ply Gem business and its leadership team as they continue to demonstrate strong financial performance against the challenging market conditions that currently exist in the residential housing market. We look forward to working with Ply Gem's management team to continue building the business."
