PlyGem Windows 

Contractor Series

(Formerly Great Lakes Window, Grandview 3000)

Contractor Series Replacement windows are designed to perform, but more importantly, they  are designed to give you the best value. 

PlyGem Contractor Series windows feature Pinch Fusion-welded construction with a solid one piece unit for long term durability.

The Warm Edge glass spacer system within PlyGem Pro Series windows reduces thermal transfer around the glass perimeter by utilizing a unique U-shaped channel to separate glass panes and interrupt the natural flow of heat to cold.

Available in both HP glass (Low-E/argon) and Low-E options

All product styles meet ENERGY STAR®

NFRC rated and certified

Designed with narrow sight lines for maximum viewing area on all styles

Limited Lifetime Warranty

We believe so strongly in the durability of our windows that we back each window unit with our hassle-free Limited Lifetime Warranty. Lifetime means your windows are protected under the warranty for as long as you own your home. And your warranty is transferable to the next home-owner. Which helps you protect your investment by increasing your home's resale value.
