Are Your Window Frames Getting Warped?

From classic styles to custom windows, wood offers many aesthetic benefits despite its vulnerability to common problems like rot and deterioration. Vinyl is a more durable and longer-lasting alternative to traditional wooden frames, but it’s still vulnerable to warping.

Warping can compromise a window’s energy efficiency, promote air leaks and even necessitate the need for premature replacement. Today, Renewal by Andersen® of Austin explains the causes of warping and offers tips on how to avoid this common problem.

Why Windows Warp

Warping can happen to almost any type of window but is most common with vinyl windows. This is because the plastic chemical components of vinyl are susceptible to thermal expansion, that is, the constant expanding and contracting that happens when temperatures rise and fall. 

A Combination of Materials

Renewal by Andersen® developed a product that provides a solution to this common problem: Fibrex®. This material features the strength and durability of vinyl, but unlike vinyl is resistant to thermal expansion. This is thanks to its unique polymer composition that retains its shape in a wide range of temperatures. In addition, Fibrex is low maintenance and aesthetically versatile.

Avoiding Warping Problems

Warping can cause sliding windows and other window styles to become inoperable. You can avoid these issues investing in windows with Fibrex frames. The durability of Fibrex ensures your windows will perform flawlessly for decades.
