Unmatched Durability and longevity

Outperforms and Outlasts vinyl and aluminum

The Ultrex® Fiberglass Advantage
Strong, stable, durable and virtually indestructible, Ultrex® is possibly the perfect building material, creating windows that leave other materials in the dust.  It’s so strong, 8x stronger than vinyl, that they have to use diamond-edge blades to cut it.  It doesn’t expand and contract in weather extremes, so it gives you an airtight seal.  And Ultrex® resists the ravages of time, cold, heat and pressure to provide the most worry-free, maintenance-free windows available today.

Wood-Ultrex® Windows
Features exteriors of Ultrex® fiberglass and beautiful, real wood interiors.

All Ultrex® Windows
Ultrex interiors and exteriors offering exceptional aesthetics, outstanding durability, unbeatable performance.  Virtually indestructible exteriors in six finishes.  Low-maintenance classic white profiled interiors.
