This innovative material combines the strength of wood and the easy maintenance of vinyl. For a long product lifecycle, we made Fibrex twice as stable and rigid as vinyl. The stronger, thinner frame provides a wider glass area for an unobstructed view. It is also strongly resistant to mold and rot due to a special polymer formulation that surrounds and coats each individual wood fiber.
Our products, including double-hung, picture, and casement windows in St. Charles, MO, all feature Fibrex. We guarantee that it will not rot, fade, flake, and blister, so you can save on repair and maintenance. It will also remain stable against extreme temperature changes.
