For a long time, Renewal by Andersen® has been leading the replacement windows industry. With the help of new technology and innovative minds, we successfully developed our patented Fibrex® frames. To learn more about this game-changing material, we collected some frequently asked questions for your reference.
1. What Is Fibrex?
Fibrex composite material is made from reclaimed wood fibers and thermoplastic polymer. It combines the well-known durability of wood and the low-maintenance feature of traditional vinyl, and promises to resist bowing, cracking, and rotting. This idea was initially developed when Andersen reused sawdust obtained from wood windows production as an effort to cut down costs.
2. How Does Fibrex Compare With Vinyl Windows?
Compared to Fibrex-framed windows, vinyl replacement windows are more susceptible to sagging or warping when exposed to extreme heat. The wood fibers also keep the expansion rate of Fibrex at a low level, keeping the frame in perfect shape and your windows airtight with no room for leaks.
3. What Are the Other Advantages of Fibrex?
On our windows, Fibrex is often paired with High-Performance™ Low-E4® glass which blocks thermal transfer and optimizes insulation activities. It also comes in slimmer frames which allow more glazing and an unobstructed view of your lush garden. And since it doesn’t use wood preservative treatments, it reduces harmful VOC emissions. Finally, Fibrex is expected to retain its stability in varying climates.
4. Does Fibrex Come With Warranties?
Fibrex windows are backed by a 20-year limited warranty for Fibrex and glass, a 10-year limited warranty for the frame, sash and locking mechanism, and a 2-year limited warranty for installation. This top-level coverage is to assure customers that only get the highest quality of products and outstanding installation services.
