What is Fibrex® material?

Fibrex® material is a stronger, smoother, more durable, and longer-lasting alternative to vinyl window frames. An Andersen® exclusive product, made with reclaimed wood fiber and a unique polymer blend, Fibrex® material brings the best qualities of wooden and vinyl windows together. That means your new home improvement operates with the versatility of vinyl windows as well as the sturdiness of wood–despite extreme Denver weather, and for years to come.

Fibrex® Vs Vinyl Windows

Compared to standard replacement vinyl windows, Fibrex® material provides unmatched style, insulation, and performance:

  • Your choice of interior and exterior color is infused into Fibrex® material during the extrusion process to last for years to come without cracking or fading.
  • All Renewal by Andersen windows are guaranteed to look and function just as well as the day they were installed for years. Learn more about our warranty!
  • Fibrex® material’s strength and durability makes for narrower frames. Narrower frames make for more glass in your window and less material obstructing your view of the outdoors.
  • Fibrex® material is crafted from reclaimed wood and polymers, can help reduce heating and cooling costs, and reduces VOC emissions – all of which helps keep your energy costs lower than standard vinyl windows.
  • Renewal by Andersen’s exclusive Fibrex® material contains 40% reclaimed wood fiber by weight and manufactured in the US with zero 3rd parties!

Keeping Your Denver Home Cool and Comfortable–No Matter What!

Fibrex® material is proven to keep you and your family cool and comfortable and protect them from harsh elements. Even despite variable Denver area weather, Fibrex® outperforms vinyl windows with added:

  • Home heating and cooling bill savings of up to 70%,
  • Less strain on appliances–potentially increasing their lifespan,
  • Unchanged energy efficiency over time–backed by our limited warranty!
  • And more stability in any climate compared to vinyl windows.

Combined with your choice of energy efficient double pane window glass, Fibrex® material ensures your windows perform with twice the strength of vinyl replacement windows.
