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.

"This was one of the best experiences I've ever had with a company. I ordered the windows in November and was told they wouldn't be here until July. That kind of delay the new norm so I wasn't a bit upset with the timeline. I was given an early present when they called to say the windows would be in at the beginning of May. We agreed on the week of May 16th to do the installation, there were 30 windows and a sliding door to install. They arrived promptly on their scheduled install date, and got straight to work. By the end of day one, they had all the upstairs windows complete and their work was incredible. Day two came with more of the same, the crew showed up promptly, got straight to work, and when they left they had every window downstairs installed. The third day they again arrived on-time, and got to work installing the door. The door and windows are perfectly installed. The two lads that did the installation did a phenomenal job, and were friendly to boot. I would give them more business if I had any :) The service I received from the company was great. They kept me abreast of anything that was going on with my order. I appreciate my concierge, Christina, she was good at communicating timelines and getting everything scheduled."

"The two installers were great! They were polite and hard working and they cleaned up all the outside and inside. It was like they were never here. As for the windows, I love them, not only looks great, they are efficient. Now every window in my home has Renewal by Anderson."

"We had the pleasure recently of having Andersen replace all of our windows. From the very first interaction with the office personnel through the completion of the project, they have been nothing but professional. From Brian our sales rep to Christina the appointment scheduler, they were a pleasure to interact with. Installers Keith, John, and Evan were fantastic to work with. They went above and beyond to repair an area which was slightly damaged during the removal of a window...caulked and painted it. They took extra precaution to ensure the floors were covered while working inside and cleaned up each day inside and out. We love the look of our new windows and can't wait to enjoy the savings in utilities they'll provide. Thanks so much Renewal by Andersen!!"
