We developed a material that is 2x as strong as vinyl, performs better when exposed to extreme temperatures and delivers exteriors that won't fade, flake, blister or peel. We call it Fibrex® material. It's made up of reclaimed wood fiber and thermoplastic polymer that is fused together and is unique to Andersen.A blend of 40 percent wood fiber by weight, mostly reclaimed from Andersen manufacturing processes, with 60 percent thermoplastic polymer by weight, some of which is also reclaimed. Blocks thermal transfer nearly 700 times better than aluminum to help reduce heating and cooling bills.
