Fibrex: Andersen's Sustainable Frame Material

About Fibrex Material

Fibrex® material combines the strength and durability of wood with the maintenance ease of vinyl. It even offers builders and owners the comfort of choosing a sustainable, green building material. Andersen uses Fibrex material across its product lines. But Fibrex material is more than just environmentally responsible. It’s also durable and beautiful.

WindowRama - Andersen Fibrex MaterialWhat Makes Fibrex Sustainable?

  • Composition: We blend 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. Pre-consumer Fibrex material is also reclaimable.
  • Fibrex material 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.

How Durable is Fibrex Material?

  • Fibrex material is twice as strong as vinyl, so weathertight seals stay weathertight.
  • Fibrex material retains its stability and rigidity in all climates.
  • Our unique fabrication process blends the color with the Fibrex material during production for long-lasting beauty.
  • Fibrex material resists rot, decay and fungal growth, and won’t flake, blister, peel, pit or corrode.
