How Do Fibrex® Material Frames Resist Window Warping?

Warping is a common problem inherent to wood or vinyl windows, and has been known to affect window functionality and aesthetics. In today’s post, Renewal by Andersen of Kansas City shines the spotlight on our solution to warped window frames: Fibrex® material.

What Causes Warped Windows?

Warping is caused by changes in outdoor moisture and temperature levels. Wood is particularly vulnerable to warping because wood fibers expand and contract unevenly due to natural variations in fiber size. When wood absorbs moisture, it causes swelling that doesn’t always revert, which can result in significant warping. This is why wood windows require regular reapplication of paint or waterproofing. Vinyl windows, on the other hand, are vulnerable to extreme heat, which causes warping.

Fibrex® Material

We at Renewal by Andersen understand that every home improvement is an investment. This is why our parent company Andersen® Corporation spent decades developing Fibrex® material. Development began in 1958 and the resulting material wasn’t patented until 1991. Fibrex is a composite made from wood fibers and polymer. It combines the strength and durability of wood frames and the low maintenance qualities of vinyl, plus superior resistance to warping thanks to its even thermal expansion and contraction rates.

Other Features of Fibrex

Resistance to warping is just one of the many benefits of our Fibrex material frames. As a manufactured material, Fibrex can be made into virtually any shape, size and profile required to build our custom replacement windows. Its inherent strength allows us to build slimmer frames — which means bigger glass areas — without compromising structural integrity. Our factory-applied coatings are warranted against peeling, cracking or fading, and they require minimal maintenance.

Fibrex material frames also resist thermal transfer. Together with our High-Performance™ Low-E4® glass, Renewal by Andersen replacement windows are among the most energy-efficient replacement windows available. Our replacement windows bear certification from the NFRC and ENERGY STAR®, which means they can help you save on your heating and cooling bills.
