How Fibrex® Frames Resist Window Warping

Vinyl and wood windows are usually among the top choices for new replacement windows. They’re generally reliable, but you also have to take note of their disadvantages – such as warping. This happens because the materials aren’t built to handle excessive heat. Extreme exposure to the sun causes vinyl and wood windows, in particular, to deform and lose their structural integrity.

Window Warping

Fortunately, Renewal by Andersen® of Wyoming, the leading local provider of windows and sliding patio doors, is fully aware of this phenomenon. That said, we offer the best alternative to wood and vinyl: Fibrex® frames. Here’s why our exclusive composite framing is resistant to warping. 

  • Fibrex is made from composite materials. We use Fibrex to build the sash of our window products to combine the advantages of wood and vinyl while eliminating their drawbacks. We mix reclaimed wood fibers with thermoplastic polymers to keep the frame durable and protect against moisture damage. During the manufacturing process, our special polymer formulation fills and surrounds each piece of the wood fiber.
  • Fibrex is guaranteed not to deform. If you choose us to provide and install your replacement windows, you’ll get outstanding warranties. One of which covers defects of components made of Fibrex, including cracks, flakes and blisters. This warranty is good for 10 years from the original installation date. In case of damage, we’ll cover the replacement parts and labor cost.
  • Fibrex is scientifically proven to withstand extreme conditions. The durability of our Fibrex material is backed by science. A few years ago, we removed 10 Andersen® Corporation windows from one of our Minnesota customers after enduring intense winters and summers for two decades. As per ASTM E2068, the results of our tests reveal that our windows showed no signs of chipping, cracking and peeling.

If you’re in the market for top-grade, warping-resistant windows, turn to Renewal by Andersen of Wyoming. Aside from windows, we also offer stylish and equally durable patio doors.
