PlyGem Windows 

Pro Series 

(Formerly Great Lakes Window , Grandview 4000)

Built to Last

PlyGem Pro Series windows feature Pinch Fusion welded sashes and mainframes for high strength and high energy-efficiency. Best of all, their beauty will last because they're made of maintenance-free polyvinylchloride (uiPVC).

The color of uiPVC is through-and-through, so your windows will never need painting and scratches won't show. The vinyl also won't conduct heat or cold, dramatically reducing frost and condensation. And unlike aluminum or wood windows, a simple wash with soap and water keeps PlyGem Pro Series windows looking like new year after year.

Weathertight Meeting Rails

Our double-hung and slider windows feature an Integral Interlock with double weatherstripping, an airtight seal and extra security.

Warm Edge Glass Spacer System

The Warm Edge glass 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.

Warm Edge glass spacer is one continuous piece creating a stronger, more energy-efficient insulated glass unit. Plus it flexes with glass expansion and contraction to ensure a strong seal for the life of the window.

Low-E Glass Efficiency

Single pane glass windows offer poor insulating performance

PlyGem Pro Series windows offer the HP Glass System - HP glass has a 7/8" single-surface multilayer vacuum-deposition Low-E insulated glass unit with argon gas. Argon gas is 40% denser than air which means more energy efficiency for your home.

We guarantee it.*

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.
