Advantages of Fibrex

Renewal by Andersen of St. LouisLooking for durable replacement windows? Renewal by Andersen’s exclusive Fibrex® frame and sash material lasts longer, looks better, and performs beautifully!

Fibrex is a composite of wood fiber and thermoplastic polymer. The Fibrex production process itself makes this material more sustainable than more traditional building materials. The compounds that make up Fibrex™ are taken right from the excess of its own production process. This means no waste materials. Plus, the added durability of Fibrex means that homeowners do not need to replace their windows as often. This means that, unlike wood, aluminum, and vinyl, Fibrex will not be piling up in landfills any time soon.

Once installed, Fibrex blocks thermal transfer, helping to reduce monthly costs for heating and cooling your home.It never needs to be treated with paint or stained, and resists rot, decay and fungal growth, and won’t flake, blister, peel, pit or corrode.*

Fibrex can be crafted to mimic the look and texture of nearly any other material, especially wood. For homeowners who want the rustic look of a wood framed window, but don’t want to deal with poor energy efficiency or constant maintenance, a Fibrex window from Renewal by Andersen is the perfect solution.

The sustainability, durability, and beauty of Fibrex makes it a smart investment for homeowners in St. Louis. And only one local company carries Andersen Fibrex windows- Renewal by Andersen of St. Louis.

"The salesman had previously sold us new windows and was very informative and not a bit pushy. The installation was excellent and as advertised absolutely nothing was left for me to clean up. Highly recommend Renewal by Andersen of St. Louis👍"
