All Renewal by Andersen windows are made with Fibrex®: a composite material proven to support glass with twice the strength of vinyl. This enables Renewal by Andersen windows to stand the test of time without breaking or flaking—even in extreme weather conditions.
The extrusion process of Fibrex® also allows frames to be saturated with color. Choose from a range of colors beyond white and off-white and enjoy years of flake-free color vibrancy. Plus, every variety of replacement window features additional style options from grilles to hardware so you can design one to fit you and your home.

20 Year Durability Study
A lot can change in 20 years’ time. Your windows shouldn’t. Recently, we pulled a group of our original windows out of their home, more than two decades after the window installation. These were the actual windows that had been in a real house and used by homeowners on a regular basis…and enduring extreme weather conditions. With more than 20 years of enduring extreme climate –bitter, brutal winters; hot, muggy summers and everything imaginable in between, the original Renewal by Andersen windows still opened and closed as easily as the day they were installed. And what’s more, our Fibrex material retained its strength, and there was no cracking, peeling, or chipping. This is the quality that you can expect from Renewal by Andersen replacement windows and patio doors.
Warranty
Every Renewal by Andersen window and patio door installation is backed by an unbeatable 20-year limited warranty. It includes 20 years on glass, 2 years on installation, and 10 years on frame and hardware. It’s non-prorated and fully transferable, should you sell your home. Ask your Renewal by Andersen sales consultant for complete written details.
