The Many Advantages of Fibrex®

Renewal by Andersen’s® exclusive Fibrex® material lasts longer*, looks better, and performs beautifully! This advanced composite of wood grain and thermoplastic polymer is unparalleled in the window industry and is light-years ahead of any wood, vinyl, or aluminum material when it comes to durability and sustainability. For homeowners in Spokane, replacement windows that utilize Renewal by Andersen’s exclusive Fibrex material is a smart investment towards the future.

Renewal by Andersen’s exclusive 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.* The extreme durability of this outstanding material makes it a smart choice for homeowner across the country who are sick and tired of maintaining wood, vinyl, or aluminum window frames.

Choosing Fibrex windows from Renewal by Andersen is also a smart choice for the environment. Renewal by Andersen’s exclusive Fibrex material frames and sash contain 40% reclaimed wood fiber by weight, much of which is reclaimed from Andersen Corporation’s wood window manufacturing facilities. This makes for a sustainable, low waste production process that makes Fibrex a more environmentally conscious choice. In fact, thanks in large part to their exclusive Fibrex material, Renewal by Andersen windows have achieved the highest SCS certified recycled content of any window replacement company.

Durability and sustainability aside, choosing Fibrex windows is a smart investment in the long run thanks to Renewal by Andersen’s industry-leading warranties. Renewal by Andersen offers one of the strongest window and door replacement limited warranties you will ever find.*

"Adam and Josh were great! They showed up on time and worked quickly. My 1907 windows that leaked air are gone but the historic style isn’t. And it didn’t cost nearly as much as I expected!"
