COMPOSITE - THE SMART ALTERNATIVE TO VINYL
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*
