• Expands Ply Gem’s national window footprint

• Low risk alternative for expanding operations in the West versus green-fielding

• Allows production to be shifted from the East to service Ply Gem’s existing West Coast customers

• CT has balanced end market sales mix of 52/48 New-Construction versus R&R

• Although this is a platform acquisition for Ply Gem, opportunities for synergies & cost savings exist

CertainTeed Window
Acquisition

Ply Gem completed the acquisition of CertainTeed’s vinyl window and patio
door business on September 30, 2007 for $35.0 million

Strategic Acquisition Rational:

The integration of AHE is completed and exceeded expectations.

– No loss of customers, suppliers or unplanned employees

– On pace to exceed $38.3mm in synergies, an increase of $16.3mm, or 74.1%
versus original estimates

– Strategic sourcing savings substantiated through events including:

• New contracts signed with 3 of 3 PVC resin suppliers

• New metal contract has been signed with supplier

• Original and current model do not include savings on micro ingredients,
packaging, or other raw material buys that are likely to be realized through Ply
Gem’s strategic sourcing process

• Original and current model do not reflect any savings on the PVC resin buy for
Fencing or Windows which will be realized as a result of the new PVC resin
supply contracts

– Original model assumed one vinyl siding plant closure in versus two with
accelerated timing and significantly higher savings being realized than were
conservatively estimated in Ply Gem’s original model

– Original head count reduction based upon 40 employees, but actual
headcount reduction will be a minimum of 54 employees.

AHE Integration Update

Management believes $38.3 million in annual cost savings and synergies are readily achievable with

opportunity for significant upside
