Fibrex® – Combining Strength and Style for Top Replacement Windows

Only Renewal by Andersen windows have the exclusive Fibrex® frame and sash material. Fibrex gives you the strength, durability and insulating value of wood and the low maintenance of vinyl replacement windows. It comes with our exclusive limited warranty that ensures you that our windows last and look great for years to come.

What is Fibrex®?

Fibrex is a blend of wood fiber and thermoplastic polymer. The color of the window frame is blended during the manufacturing process so the color stays true. Because it’s a combination of wood and plastic, it offers the benefit of both. It won’t decay or rot like wood and is twice as strong as vinyl. No matter the weather, it seals weathertight. It’s better than aluminum windows because it blocks thermal transfer nearly 700 times better so your heating and cooling bills are lower with windows made with Fibrex.

Advantages of Fibrex®

There are four main advantages of Fibrex:

1. Sustainability – A significant percentage of the wood used in the manufacturing process is reclaimed from Andersen Corporation’s wood window manufacturing facilities. Some of the thermoplastic is also reclaimed. This combination makes it an extremely sustainable product.
2. Energy Efficiency – Fibrex is as insulative as wood but it creates a weathertight seal that significantly reduces energy leaks. It has very little thermal transfer so even in the sun, the window frame is never extremely hot and in winter never freezing cold.
3. Low Maintenance – Fibrex material never needs painting so you won’t spend your weekends in the hot sun scraping and sanding your windows.
4. Lasting Beauty – Because the of the unique manufacturing process, the color is injected during the manufacturing so your color stays truer longer. Not only does the color resist fading but Fibrex doesn’t pit, rot, crack or corrode making for a window that lasts and looks better longer.
