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.

"Renewal was fantastic! They kept you in the loop from ordering to installation. They informed you at every step of the process of what was happening. The installers were kind, courteous, and professional. Everything was cleaned up after the installation. It was as if they hadn't been there except to see your beautiful new windows. I highly recommend them."

"3rd time using RBA for window replacement. Again, a very positive experience, the windows are great, the installation was done right, the professionalism was apparent from start to finish. Still have existing windows to be replaced and will definitely use RBA again to do it in the future."

"Renewal by Andersen was a good experience for us in replacement of our windows. From the initial meeting with the sales representative, Leslie, through the waiting period for manufacturing, and then to the installment process, our experience was excellent! Communication is key for me and we were kept informed and updated as our windows were being ordered and manufactured. Calls to update us on the installation process were welcomed and appreciated. They know how much is too much so they don't pester you with unnecessary contact. We love our new windows!!! Did I say that already??😂 We can tell a major difference in reduced Street noise and also the temperature at our windows. Excellent company, highly recommend!!"
