How Well Does Fibrex® Age?

Quality windows last longer and add more value to your home. Just like the other areas of your home, windows should be maintained regularly. They do not only add beauty, but increase energy efficiency as well.

As a  windows company, Renewal by Andersen® of St. Louis has innovative new materials with which to make window frames. Our patented Fibrex® framing material, for one, is a composite that combines the strength and stability of wood with the low-maintenance qualities of vinyl. It is an eco-friendly material, made from 40% recycled wood fibers and 60% polyvinyl chloride (PVC).

Why Choose Fibrex®?

Fibrex lasts a long time, and it is two times stronger than vinyl. We ensure that all our windows are tested to make sure they don’t contract and expand due to changes in temperature.

But how do we test these windows? We do tests on-site and more specific tests in the lab. Even after 20 years, Fibrex frames will experience no cracks or peeling, and will remain easy to operate. 

Replacement windows from Renewal by Andersen are made of Fibrex. They are strong and operable and proven to perform well regardless of their age.

Apart from the Fibrex material, our windows also come with our High Performance™ Low-E4® glass that reduces heat transfer. Get started with your new window and doors project today by calling Renewal by Andersen of St. Louis at (314) 332-2364, or fill out our online contact form to request an estimate. We serve clients in Missouri, including Chesterfield.

"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!!"
