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.

Read about the results of a long-term durability study done on 10 Andersen windows here.

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

"Quality product, quality workmanship. Everyone I interacted with at Renewal by Andersen of SW Missouri had pride in their work from sales to financing to project oversight to installation. It must be a great company to work for because that shows in the professionalism of the staff. Best of all, they want happy customers and go out of their way to make sure that happens. Yes, I love my windows (but I knew I would--it's a great product). Friendly, helpful, easy financing, and yes--they pass costs on to the customer for this, but it meant that I was able to get the windows I wanted and needed for my creaky, lopsided old house. Couldn't be more pleased."

"The company representative who met with me initially was very direct, told me how the process would go, explained about why Anderson windows are of such good quality and how they stand by their products and their workmanship. My 3 windows arrived when they said they would, & the men who installed them were very professional, polite, & efficient. They showed me how the windows work and left the room as tidy as it was before they did the installation."

"We just had our windows done by Renewal. They kept us informed about the progress of manafucture & installed at the approximate date. Good qualtity & if you didn't know that there were screens on the windows you would think they were missing. Very clear view. Great in this hot weather, the house stays cool."
