Ply Gem

Ply Gem builds vinyl, aluminum-clad, and aluminum windows across a numbered series lineup, with triple-pane glass packages available on higher tiers.

Ply Gem is a large exterior-products manufacturer whose window division spans several frame materials and a numbered series catalog. This page reports what Ply Gem states on its own windows overview about materials, glass packages, and energy certification.

Frame Materials and Series

Ply Gem builds windows in more than one material. The company describes vinyl, aluminum-clad, and aluminum windows, and states that its aluminum-clad option pairs the beauty of wood with a durable, easy-to-maintain aluminum-clad exterior.

The catalog is organized as numbered series, including the 1100, 1500, 3700, 4700, 4800, and 5000 Series, alongside named regional lines.

Glass Packages and Energy

Ply Gem offers upgraded glass on its higher tiers. The company states that its HP2+ and HP2MAX glass packages feature triple-pane units with Low-E coatings and argon.

On certification, Ply Gem states that its windows are ENERGY STAR 7.0 certified in many configurations, and references U-Factor, Solar Heat Gain Coefficient, and air leakage as the measured performance values.
