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.

"The installation crew was very professional and answered what questions I had. And they cleaned up when they were finished. We're very pleased with our windows & patio doors. Highly recommend Renewl by Anderson."

"Very pleased with installation of six windows and a ProVia entry door. I love the look of the windows and door. I am pleased that my wife is thrilled with the look of the door. She is very pleased that the bronze color fits in well with the color of the brick."

"I just had my Renewal by Andersen windows installed and couldn’t be happier, the entire process went very smoothly. The windows are high quality and look great. But the installers Roy, Zack and Jordan were the stars, they introduced themselves upon arrival walked me thru everything they were going to do and when they finished took me to each window to make sure I was completely satisfied. They were clean and courteous and I would definitely recommend and have them work in my home again."

"Wonderful experience with knowledgeable, competent employees. We had Andersen windows in a previous house & didn’t even consider anything else this time. After replacing our patio door almost two years ago, we replaced all our windows this year. What a difference over builder-grade windows, especially in the really cold temperatures we’ve had this year. Andersen windows may be a little more expensive than other brands, but they are top quality."
