Fibrex® material is a revolutionary window frame material that is exclusive to Renewal by Andersen. Using Fibrex®, Renewal by Andersen produces durable, energy efficient windows that combine the strength of wood and the easy maintenance of vinyl.

Fibrex® material sets itself apart from all other window materials from the moment production starts. Unlike the production processes of wood or vinyl, which leave tons of excess material that just ends up in a l andfill, Renewal by Andersen’s exclusive Fibrex® material frames and sash contain 40% reclaimed wood fiber by weight. Much of the wood fiber used to make this exclusive Fibrex® material is reclaimed from Andersen Corporation’s wood window manufacturing facilities. This eliminates the majority of waste and allows for a far more sustainable product.

The product itself is a composition of wood grain and thermoplastic polymer. This combination makes for an extremely efficient material, one that blocks thermal transfer 700 times better than aluminum. This helps your heating and cooling systems work only as directed and limits the amount of energy needs to keep your home at a comfortable temperature.

Further setting itself apart from wood, vinyl, or aluminum, Fibrex® offers a beautiful aesthetic that will not be tarnished by mold, mildew, rot, chipping, warping, or corrosion*. With limited annual maintenance, your Fibrex® windows will look factory fresh for years to come.

Reviews

"Love the windows and patio door. We want to finish the whole house when we can financially. We give Anderson and employees, especially the sales rep Mike that came to our house, the highest rating. Mike was knowledgeable and courteous. Also not high pressure."
