Composite (Fibrex) Windows

Composite – The Smart Alternative To Vinyl


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.

 

What Is Fibrex® Material?

  • 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.
  • Reduces VOC emissions because no wood preservative treatments or painting is required.
  • Twice as strong as vinyl, so weathertight seals stay weathertight.
  • Retains its stability and rigidity in all climates.
  • A unique fabrication process blends the color with the Fibrex® material during production for long-lasting beauty.
  • Resists rot, decay and fungal growth, and won’t flake, blister, peel, pit or corrode*
