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.

Reviews

"Excellent service and product! They checked in with me every few weeks while we were waiting for the order. I was impressed with Sam, who measured my windows and headed the installation crew. He was respectful and patient with his team. They cleaned up after themselves. Before the new windows I had huge windows that didn’t open. Now I feel much safer and get better temperatures in those rooms."

"My experience with Anderson Renewal was amazing! From the first meeting with Miranda to choose my windows and doors to the installation provided by Tim and his crew was a pleasure! I just bought a home built in the 1960's that needed new windows and a new double front door with sidelights. As everyone knows Anderson Windows are great, but it was the people I interacted with from Anderson that made it such a great experience. It took three days for the windows and door to be installed and they "worked" every minute they were here. My huge front door took most of the day to install because they had to put in a new header and other improvements to make it fit! They even put up new drywall on the inside. Many people in the neighborhood have stopped by to comment on my beautiful front door! I think the crew left my house cleaner than it was before they started! Constantly cleaning up after themselves. I am thrilled with my windows and feel lucky to have met the team at Anderson."

"Very professional staff . No pressure sales. The job they do is neat and clean, no cleanup left for the owner. Communication is great. Always informed on the status of of your product, AND the tin of cookies you receive afterwards is a pleasant plus."
