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.

"Renewal by Andersen of St Louis is an outstanding company. Our third phase of replacing windows was accomplished flawlessly, just like the first two phases. All interactions, from ordering to installation, were very professional. The installers were knowledgeable and went above and beyond to solve an issue when a minor structural problem was encountered."
