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.

"Very pleased with installation of six windows and a ProVia entry door. I love the look of the windows and door. I am pleased that my wife is thrilled with the look of the door. She is very pleased that the bronze color fits in well with the color of the brick."

"I just had my Renewal by Andersen windows installed and couldn’t be happier, the entire process went very smoothly. The windows are high quality and look great. But the installers Roy, Zack and Jordan were the stars, they introduced themselves upon arrival walked me thru everything they were going to do and when they finished took me to each window to make sure I was completely satisfied. They were clean and courteous and I would definitely recommend and have them work in my home again."

"Wonderful experience with knowledgeable, competent employees. We had Andersen windows in a previous house & didn’t even consider anything else this time. After replacing our patio door almost two years ago, we replaced all our windows this year. What a difference over builder-grade windows, especially in the really cold temperatures we’ve had this year. Andersen windows may be a little more expensive than other brands, but they are top quality."
