A Better Way To Replace: Fiberglass Windows And Doors

Strong, stable, durable and virtually indestructible!

Ultrex fiberglass is possibly the perfect building material, creating windows and doors that leave other materials in the dust. Made from pultruded fiberglass, Ultrex outperforms vinyl on nearly every measure.


Ultrex is as strong as steel and eight times stronger than vinyl. In fact, it’s so tough, we have to use diamond-edge blades just to cut it to size. The rigid structure of Ultrex ensures a true and perfect fit that lasts. Even after years of use, Integrity windows will continue to slide, crank, raise and lower as if they were installed yesterday. And our patented finishing process outlasts the competition, resisting fading that can plague other composite materials. Our thick acrylic finish bonds directly to the surface to prevent dings, mars and scratches.
