Exclusive Fibrex Frames

Renewal by Andersen’s exclusive Fibrex® frames are used to craft durable, beautiful, energy efficient windows that are custom fit to your home and your style. This composite of wood grain and a thermoplastic polymer retains its stability and rigidity in all climates and is twice as strong as vinyl, so weathertight seals stay weathertight. This helps to eliminate drafts that can lead to higher heating and cooling bills. For homeowners seeking better replacement windows in Long Island, this weathertight seal is crucial.

Fibrex material offers the strength and insulating value of wood with the low maintenance features of vinyl. Fibrex material never requires painting and will not crack, pit, corrode, or rot.* In a unique fabrication process the color of your choice is blended with the Fibrex material during production for long-lasting beauty. Working with an experienced Renewal by Andersen design consultant, you can find your ideal frame and sash color and see that same vibrant color year after year with little required maintenance.

Perhaps the greatest aspect of Fibrex is its sustainability. Fibrex material frames and sash contains 40% reclaimed wood fiber by weight, much of which is reclaimed from Andersen Corporation’s wood window manufacturing facilities. Much of the thermoplastic polymer is reclaimed as well, making the production process behind Fibrex one that produces very little waste.

Fibrex is also utilized in Andersen Sliding and French Patio Doors. The same durability, energy efficiency, and beauty that makes Fibrex the perfect window frame and sash material makes it ideal for patio doors.

"I was very impressed with Renewal by Andersen. They showed up in time and we received several follow up phone calls as the installation was being done as well as the sales representative stopping by to check in on the installation. The delivery/ installer was very professional. I would highly recommend Renewal By Andersen."
