Preventing Windows Warping With Fibrex®

Warping is a typical problem with windows for a variety of reasons. Heat and moisture damage are the most common causes of this issue, which occurs more frequently in wood and vinyl windows. When a window’s frame is crooked, twisted, or bent, you know it’s warped.  

Warping is a significant issue that frequently happens with conventional wood and vinyl window frames. If left untreated for an extended period of time, it can significantly reduce your home’s energy efficiency and curb appeal. Renewal by Andersen® of Atlanta — a leading provider of high-quality casement windows — shares all you need to know about warped windows in this article, including what causes them and how to repair them.

How Do Fibrex® Windows Stand Up to Warping?

Fibrex is a warp-resistant window material that is an excellent substitute for wood or vinyl. Fibrex combines the strength and insulating characteristics of wood with the low-maintenance characteristics of vinyl. It resists warping better than conventional window materials. This is why:

  • Unlike vinyl, this advanced composite does not expand or contract much in response to dramatic changes in weather and temperature. Your windows will retain their shape, which will ensure their strength and durability.

  • Fibrex is made from reclaimed wood fibers and polymers and hence does not have the defects associated with wood. Because this material does not absorb and retain moisture, our windows, particularly double-hung windows, are less prone to mold and rot–factors that contribute to warping.

  • Fibrex is abrasion, corrosion and crack resistant. Due to the material’s hardness, it enables windows to have a stronger, more airtight seal, hence minimizing energy loss.

Other Benefits Of Fibrex

Fibrex has more than just exceptional warp resistance on its side. We can make some of the most energy-efficient replacement windows by combining them with our High-Performance™ Low-E4® SmartSun™ glass. But that’s not all. Because of Fibrex’s strength and flexibility, we can create windows of any size or form, including those with narrower frames and larger panes to maximize natural light. A robust 10-year limited warranty further ensures your safety.
