Fibrex Composite Material
Renewal by Andersen has revolutionized how windows are manufactured since its founding in 1903. One of our most innovative material ideas, Fiberx material, was developed in the U.S. in 1959. Our guiding principle has always been to “make a product that is different and better,” and in 1992, Andersen perfected what is now the Fibrex material.

A Smarter Material with Unmatched Performance
With super window materials made to retain their stability and rigidity, Fibrex outperforms all competition for decades to come. Made from a combination of 40% reclaimed wood fibers and a blend of 60% thermoplastic polymer, our product gives windows strength, durability, and low maintenance compared to other materials.
Fibrex Material is a Better Choice
Unlike many other window materials, Fibrex material is vastly superior to vinyl, making it a clear choice for windows. Compared to vinyl, Fiberx will not crack, pit, corrode, or rot. In addition, Fibrex has superior scratch resistance to painted vinyl. Fibrex’s finish is 12 times thicker than painted vinyl. Fibrex material endures extreme heat and has double the strength of Vynl.
Fibrex Material | Other Materials | |
|---|---|---|
Strength | Because Fibrex® material is strong, we can make our sash and frames narrower and that means more glass, more view. | Vinyl frames are known to have a higher expansion/
contraction rate and can bow, breaking the glass seal. |
Insulation | Fibrex material has superior thermal insulating properties. Combined with Andersen® High-Performance™ Low-E4® glass, this helps your home stay warmer in winter and cooler in summer. You can save money on your energy bills. Your home feels more comfortable. | Aluminum window frames conduct heat and cold. Heat leaks out of your house in the winter and into your house in the summer. |
Low Maintenance | Fibrex material never needs scraping or painting. It won’t rot, decay or mold* | Fiberglass frames are painted and may need regular maintenance.
|
Beauty | Renewal by Andersen replacement windows preserve the architectural beauty of your home. Frame and sash design reflect the shape and lines of your original windows. The unique extruded Fibrex material can be made into any kind of window – including curved specialty windows. | Most replacement windows have square profiles that may look artificial in your home. Vinyl frame material is often thicker, reducing glass area. Fiberglass can only be made into straight lineals. |
Environmental Responsibility | 40% of the raw material by weight used to make Fibrex material is clean, reclaimed wood fiber. Reclaimed materials in the manufacturing process can also be reground and reused. Renewal by Andersen® windows are ENERGY STAR® qualified for meeting strict energy efficiency criteria set by the U.S. Department of Energy. | Fiberglass is a thermoset material and cannot be reformed into new profiles. |
Warranty | A window is not just glass and some framing material. It’s a precise combination of glass, frame and quality installation. We back it all with a 20/2/10 Limited Warranty* that is one of the best in the business. | Installation is rarely covered in the written warranty. |
