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.

"Our experience from the salesman to the installers was seamless and fantastic. We were sold with the construction and materials of the Renewal by Andersen windows and doors. Would highly recommend this product and team of installers. Thank you for a great job! "

"We had such a great experience with Renewal by Anderson. The salesman was great in explaining the product as well as the process. He was prompt and pleasant. He measured our old door and scheduled another to remeasure just in case. The door took some time to make but we were made aware of the COVID delays. They called me several times to inform us of the progress. Actually we were told it was going to be the middle of August and it turned out to be a week early. The install was awesome..."
