Fibrex® Frame Material: Why Does It Age So Well?

The replacement windows of Renewal by Andersen® are made of Fibrex®, a composite material composed of wood fibers and thermoplastic polymer. This combination gives it the stability of wood and the low-maintenance features of vinyl. In fact, it has been scientifically proven to stand the test of time.

“How so?”, you might ask. Here’s how!

Performance-Tested Window Frames

Ever since Fibrex was patented in 1992, Renewal by Andersen has been performing rigorous testing on all windows as part of the company’s Signature Service. This concept involves a superior start-to-finish-process, coupled with the best people in the industry and decades of exclusive product innovation.

A long-term durability test is one of the more recent studies they conducted to see how well windows perform after years of being installed. For this, the installers removed 10 double-hung windows from a Minnesota customer’s home – 20 years after they were first installed. On-site testing and extensive laboratory work were done to obtain findings.

According to the study, the windows were found to still be strong and easily operable as the day they were first installed. Even when they were exposed to brutal winters and humid summers, the units didn’t show signs of cracking, peeling and chipping. The study proved, once and for all, that Renewal by Andersen windows perform well with age.
