Discover the answers to some of the most commonly asked questions about Fibrex replacement windows in this post.

What Is Fibrex®

Fibrex is a unique material that features the warmth and durability of wood with the low-maintenance features of vinyl. This material is made from a combination of wood fiber and thermoplastic polymer. It makes a great window material for residential windows as it withstands bowing, cracking and rot.

Why Should You Go for Fibrex?

Home window replacement experts recommend Fibrex due to the hefty benefits it offers. When combined with Renewal by Andersen’s High-Performance™ Low-E4® glass, Fibrex offers superior energy efficiency and insulating properties. This material is so strong that it can be made into narrower frames and in virtually all shapes and sizes. It can be manufactured into all types of windows, unlike fiberglass that only allows for straight lines. Because of their durability, Fibrex windows do not require as much maintenance, saving you on upkeep costs.

Is Fibrex Protected By Warranties?

The warranty that backs a product says a lot about its reliability, strength and longevity. All Renewal by Andersen windows is backed with one of the most comprehensive warranties in the industry. Our windows come with a 20/2/10 Limited Warranty. It includes a 20-year limited warranty for Fibrex® and glass, a 10-year limited warranty for the frame, sash, and locking mechanism, and a 2-year limited warranty on installation.

"After years of watching the wind move my drapes and hours of difficult cleaning, I decided to get new windows. I went with Renewal by Andersen because of the great reviews and quality. From Brent who did the consult, Gideon who did the measuring, to Jason, Josh, and I apologize I can't remember the third installers name, this is the most professional company I've ever worked with. I own a 1994 double wide mobile home, so everything in this place is hard to work with. I had a bay window, 6 double hung, 2 awning, and a front door replaced.. They said it would take 2 days and they were done on time! I did have second thoughts about doing this mainly because of the cost, but once it was done, I was very happy I did this."
