How Well Does Fibrex® Age?

Renewal by Andersen® revolutionized the window replacement industry with an innovative material called Fibrex®. Used in various Andersen® window products, Fibrex is a composite material that combines the low-maintenance features of vinyl with the strength and durability of wood.

What You Should Know About Fibrex®

Since Fibrex material doesn’t contract or expand with changes in temperature, it is considered to be long lasting and two times stronger than vinyl.

As part of our commitment to quality, we ensure that our windows go through rigorous tests all the time. But to really prove how well our replacement windows hold up after several years, Renewal by Andersen conducted a long-term durability test on 10 of our windows.

These windows, which were all in good condition, were removed from a customer’s home in Minnesota. Since these windows have been in use for 20 years, you can bet that they have seen and withstood brutal Minnesota winters and humid summers.

To see how the windows were able to resist various elements, tests were done on site, and more extensive testing was performed in the lab. The result: the windows were still strong and easy to open, and they showed no cracking, chipping or peeling even after 20 years of use.

"I just bought my first house. My patio sliding door was rotten. So, I needed it to replace it. Renewal by Anderson of Southern Missouri listened to what I wanted and delivered it. They did a fantastic job of installing and cleaning up afterwards. They did it even in freezing rain that day I was scheduled to have it replaced. They even had a follow-up to check things out and do the touch ups. I'm amazed at there work. Great job Renewal by Anderson."

"On Feb 1,2024 my husband and I selected Renewel by Andersen for windows for our entire house. It made our house more beautiful with the picture windows. Made the outside more attractive, and on the inside. We did 14 windows. We had 4 men come to do the job in 1 day And they were very friendly, efficient,fast and cleaned up inside and outside perfectly. And most importantly we noticed the heating furnace runs less,therefore saving us money on our gas bill. We live in SW Missouri. We recommend anyone who wants to replace windows in their home to pick Renewal by Andersen. Sincerely, Darius and Nancy Durman"
