What Makes Fibrex® Windows Age Well?

At Renewal by Andersen® of Atlanta, we’re proud to install replacement windows made with Fibrex®. This composite material is a great alternative to wood, vinyl, and aluminum that’s proven to last. What makes Fibrex® a long-lasting material though?


In this post, we share the key features that make this composite material the superior choice for windows.

Innate Strength

Fibrex is made from a composite of natural wood fibers and polymer. This unique blend gives the resulting material the beauty and toughness of wood with improved resilience and durability thanks to that polymer. 

Low-Maintenance Windows

The blend of natural wood and polymer also makes them low-maintenance windows. Your new Fibrex® windows will never require scraping or repainting, and unlike wooden windows, will never rot or suffer from decay.

Narrower Frames

Innate strength isn’t the only thing you get when you have our windows company install Fibrex windows. Since our frames have higher resilience and toughness, we can make narrower window frames with more glass areas without compromising integrity!

Energy-Efficient Windows

Fibrex boasts comparable insulating properties as wood, which already gives it an advantage over metal frames. We further improve the energy efficiency of our windows by pairing it with our High-Performance Low-E4® Glass. The result: your home stays warm in the winter and cool in the summer, while also passively reducing your overall energy consumption.
