3 Frequently Asked Questions About Fibrex® Windows

We at Renewal by Andersen® are committed to providing only the highest quality energy-efficient windows and doors. In line with this commitment, we use only the best available materials available for our products, including our patented Fibrex® material. But what exactly is Fibrex?

3 Frequently Asked Questions About Fibrex® Windows

In today’s post, we answer four of the most frequently asked questions about this revolutionary material.

Question #1: What Is Fibrex®?

Fibrex is a polyvinyl chloride (PVC) and wood composite material developed by Renewal by Andersen and is used in the majority of our windows. By weight, it is composed of 40% recycled Ponderosa pine wood fibers and 60% PVC. Fibrex combines the durability of wood with vinyl’s low maintenance characteristics, which is why it is a favorite among homeowners and window installation companies alike.

Question #2: Does Fibrex Come With a Warranty?

At Renewal by Andersen, we believe that a great window is a combination of excellent materials and expert installation. All our Fibrex products are backed by the famous Andersen 20/10/2 warranty: 20-year limited warranty for Fibrex and glass, 10-year limited warranty for the frame and 2-year limited warranty on installation.

Question #3: Is Fibrex Available for All Windows?

As mentioned above, Fibrex is highly versatile and is used in almost all of our windows – from traditional casement windows to custom windows with complex curves. Andersen® developed Fibrex specifically so it can be extruded, which allows it to be shaped in all kinds of ways.

"Very pleased with installation of six windows and a ProVia entry door. I love the look of the windows and door. I am pleased that my wife is thrilled with the look of the door. She is very pleased that the bronze color fits in well with the color of the brick."

"I just had my Renewal by Andersen windows installed and couldn’t be happier, the entire process went very smoothly. The windows are high quality and look great. But the installers Roy, Zack and Jordan were the stars, they introduced themselves upon arrival walked me thru everything they were going to do and when they finished took me to each window to make sure I was completely satisfied. They were clean and courteous and I would definitely recommend and have them work in my home again."

"Wonderful experience with knowledgeable, competent employees. We had Andersen windows in a previous house & didn’t even consider anything else this time. After replacing our patio door almost two years ago, we replaced all our windows this year. What a difference over builder-grade windows, especially in the really cold temperatures we’ve had this year. Andersen windows may be a little more expensive than other brands, but they are top quality."
