Fibrex® Frames Engineered for Superior Performance

At Renewal by Andersen, we aim to change the window replacement industry. We do this by using the finest materials available, including our exclusive Fibrex® composite material.

We use Fibrex® composite to create durable, space-saving frames and sashes. The material is made of real wood fiber and a thermoplastic polymer, making it one of the strongest, most innovative materials on the market and unique only to Renewal by Andersen. 

Compared to vinyl, wood, aluminum and fiberglass, our Fibrex® composite stands out. It is more durable than fiberglass and twice as strong as vinyl. It also blocks thermal transfer nearly 700 times better than aluminum, which helps reduce your heating and cooling bills.

By using Fibrex® material, we are able to create narrower frames, which gives you more glass area and a better view. Other companies often use vinyl frames, which are thicker and reduce the glass area.

In addition, Fibrex® frames are low maintenance. The composite expands and contracts very little (even with extreme temperature swings), so we are able to offer more exterior options. This technology makes sure our windows don’t fade, flake, blister or peel.

Our Fibrex® frames are efficient, easy to maintain and extremely durable. They last for many years, especially when compared to other materials. You only have to replace your windows once with Renewal by Andersen compared to vinyl windows, which would need to be replaced multiple times over the same amount of time.
