EXCLUSIVE FIBREX

Maintain Energy Efficient Windows with Fibrex®

Only Renewal by Andersen offers the revolutionary Fibrex material for windows and doors. Our Fibrex material offers the strength and insulating value of wood with the low maintenance features of vinyl. Fibrex never requires painting and will not crack, pit, corrode or rot.* When you install doors or replacement windows that utilize Fibrex, you’ll enjoy many years of indoor comfort, low-maintenance, and energy efficiency.

The unique fabrication process behind Fibrex blends the color with the Fibrex material during production for long-lasting beauty. Fibrex does not need to be scraped or painted and will not fade over time from exposure to the sun and the elements. All that time you spent maintaining your wood, vinyl, or aluminum windows can be put to better use when you turn to us for Fibrex replacement windows. 

Renewal by Andersen is deeply dedicated to environmentally responsible production. Our exclusive Fibrex material frames and sash contain 40% reclaimed wood fiber by weight, much of which is reclaimed from the Andersen Corporation’s wood window manufacturing facilities. You won’t find Fibrex piling up in landfills like wood, vinyl or aluminum. In fact, Renewal by Andersen windows have achieved the highest SCS certified recycled content of any window replacement company.

It is thanks to materials like Fibrex and our High Performance™ Low-E4® SmartSun™ glass that Renewal by Andersen and our parent company, the Andersen Corporation, are the first window manufacturers to be Green Seal Certified.
