Benefits of Fibrex®
Many contractors limit you to just vinyl or fiberglass for window and door replacement. However, at Renewal by Andersen, we offer an exclusive alternative: our exclusive Fibrex composite material. Fibrex delivers the stability and strength of wood without the demanding upkeep. Critically, it is proven to be twice as strong as traditional vinyl. Furthermore, its insulating properties are an astounding 700 times superior to aluminum, significantly boosting your home’s energy performance. The exceptional durability of Fibrex allows for greater design freedom. Since the material maintains a stable shape with less bulk, we can manufacture narrower frames, giving you a larger glass area and clearer views. Plus, unlike less robust materials, Fibrex can withstand heat, allowing for beautiful, on-trend dark colors like black, navy, or brown without any worry of bending or warping.
