The Fibrex^® Difference

When Andersen Windows launched the Renewal by Andersen® division, it introduced a better process to the window replacement industry – and a groundbreaking new material to make the window frames. This patented Fibrex® composite material is a better window framing material for several reasons.

Strength. Fibrex material combines wood fiber with the low maintenance of premium vinyl, resulting in remarkable strength. Due to this strength, Fibrex window frames can be manufactured with narrower lines and more glass area for better views and lighting.
Stability. As a composite material, Fibrex contracts and expands very little, even in extreme temperatures. For this reason, Fibrex material can be produced in dark exterior colors than vinyl can’t.
Colors. Fibrex never needs to be painted and comes in more than 47 color combinations to match any home’s style.
Warranty. The extra strength and durability of Fibrex material will not rot, warp, crack, peel or split which allows Renewal by Andersen to offer one of the best warranties in the window industry.

When compared to wood, fiberglass and aluminum, Fibrex performs better on every level. Let us show you the difference.

From George, the salesman giving me a balance of wants and needs to Rosko and his team members doing a fantastic job on the window replacement and install. To the post inspection process and thank you package with additional information for cleaning and maintenance. All was great!

The entire team was excellent, professional, respectful, thoughtful, and was always attentive of our needs. They always asked questions before they started to make sure we were on the same page. We already noticed savings on our electricity. We are so happy we chose Renewal by Andersen.
