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.

"I'm getting ready to do my 2nd round of window installation with Anderson Windows. I really appreciate the great financing options that they offer! They have top notch sales and installation experts who are very kind and considerate of their customers' wishes. The windows I have installed look great and I am so excited to get the next group of windows put in. My house looks so much brighter with my new windows. I definitely recommend Renewal by Andersen of St. Louis."

"We recently contracted with Renewal by Andersen to replace 5 windows in our home. First of all, we were very delighted that the time from contract to installation was less than two months. Joel and Craig arrived precisely at the agreed-upon time and spent less than four hours from start to completion of installation, including time to demonstrate opening/closing the windows and any questions we had. We were very pleased with the knowledge and professionalism of Joel and Craig, and, of course, we’re very pleased with the windows and how nice they look. We definitely recommend Renewal by Andersen."

"I replaced my front door and several windows. The install team did a great job with installation and clean up. Even covered floors and stairs. The team was very courteous and did a very professional job. Now our windows look great and we love our new door. I would recommend Renewal by Anderson in a heartbeat."
