Why Fibrex® is Superior
Unlike many competitors who are limited to offering fiberglass or vinyl, Renewal by Andersen created Fibrex®, an exclusive composite material that consistently outperforms traditional options. This unique blend takes the incredible stability and structural strength of wood and marries it with the maintenance-free advantages of vinyl. Fibrex® is measurably two times stronger than vinyl and offers 700 times better insulation than aluminum.
The innate strength of Fibrex® allows our designers to create sleeker, narrower frames, maximizing your glass area for larger, more beautiful views. Plus, its heat-defying properties mean you can choose deep, dark exterior colors like black, navy, or brown without concern for warping.
