Prevent Window Rot with the Strength and Durability of Fibrex®

October 27, 2023

At Renewal by Andersen, we often talk about all the beautiful options we offer in windows and doors. Between the various sizes, sleek shapes, exciting colors, and unique finishes - it’s hard not to talk about them! But what good is a gorgeous window if it’s not long-lasting? Our durability deserves a spotlight, too. 

And the star of the show is Renewal by Andersen’s Fibrex®.

Created in 1992, Fibrex® is Renewal by Andersen’s patented composite material. Fibrex® uses a blend of 40% wood fiber and 60% thermoplastic polymer to combine wood's strength and stability with vinyl's low-maintenance benefits.

There are so many benefits of Fibrex®, including: 

Strength.

The material is twice as strong as vinyl, meaning it can withstand even the most extreme temperature swings. 

Rot-Resistance.

No flaking, rusting, blistering, peeling, cracking, pitting, or corroding here. Thanks to extensive testing, Fibrex® windows stand the test of time and are as easy to operate after twenty years as the day they were installed.

Energy-Efficiency.

Fibrex® has superior insulating properties, blocking thermal transfer nearly 700 times better than aluminum to help reduce heating and cooling bills. 

Sustainability.

Forty percent of the raw material by weight used to make Fibrex material is clean, reclaimed wood fiber. 

Low-Maintenance.

The color you choose for your Fibrex® windows is fused into the material during production, so you never have to worry about peeling or chipped paint. 

Fibrex® isn’t just another product. It’s the result of our commitment to quality. 
At Renewal by Andersen, we want to make the window replacement process as simple and seamless as possible.
