Benefits of Fibrex®

Benefits of Fibrex®

Most window or door replacement companies give you two options: fiberglass or vinyl. While these traditional materials have their merits, we’ve developed a special in-house solution, Fibrex®, that outperforms them both. Fibrex® combines the strength and stability of wood without the maintenance. It’s twice as strong as vinyl, and its unique material properties insulate 700x better than aluminum.

Because Fibrex® is super-strong, it also offers you more freedom in your design choices allowing you to opt for a sleeker, narrower frame with larger windows. And because Fibrex® can “take the heat”, you can paint it darker colors like brown, navy, or black without worry of warping.
