Great Strength and Durability
Fibrex is superior to vinyl because it is a custom-engineered product that combines reclaimed wood fiber with vinyl polymers. Our manufacturing process combines the two materials to create a stronger, lighter and better-performing material. Unlike vinyl, our Fibrex window frames stay stable and rigid even when exposed to temperature change, reducing the risk of air leaks from expanding windows. Our window frames are also twice as strong as vinyl frames, allowing us to manufacture thinner frames for more glass area.
Superior Energy Efficiency
Our Fibrex window frames contribute to our windows’ unparalleled energy efficiency. Fibrex is an effective insulator. In fact, it can prevent heat transfer up to 700 times better than aluminum. With our thin and strong Fibrex frames, you can enjoy an expansive view from your picture windows without worrying about unwanted heat gain.
Unmatched Beauty and Minimal Maintenance Requirements
Fibrex frames are also low maintenance. They do not absorb water because a thermoplastic polymer surrounds and coats every wood fiber, providing our window frames with superior resistance to decay and rot. Fibrex frames will not flake, corrode, blister, peel, crack or deteriorate. Our manufacturing process ensures that the colors on our Fibrex frames won’t fade. Our window frame colors will remain vibrant and beautiful for many years with minimal maintenance.
