VIDEO: SIZING UP FIBREX® IN CRITICAL AREAS

Video Sizing Up Fibrex In Critical Areas

Renewal by Andersen® of St. Louis is the exclusive home to Fibrex®—a revolutionary composite window material. Made from 40% reclaimed wood fiber and 60% proprietary polymer by weight, its intricate and innovative manufacturing process has earned us over 30 patents. First used in the 70s but perfected in the 90s, Fibrex has been ( and still is) the closest to perfection when all materials on the market are considered.

To underst and why Fibrex makes utopian replacement windows, let’s see how it fares in key areas:

Strength

Since nearly half of it is made from real wood, Fibrex delivers superior rigidity and stability. But unlike genuine lumber, its thermoplastic side allows it to repel moisture and resist rot and fungal growth. Compared with vinyl that exp ands and contracts a lot, Fibrex is 200% stronger.

Energy Efficiency

Fibrex is one of the best insulators on the market. It complements our high-performance glass options, contributing to your home’s overall insulation and weathertightness significantly. To put things into perspective, it conducts heat about 700 times less than aluminum.

Beauty

Its compound flows through our state-of-the-art extruder, giving us considerable latitude to create Fibrex in virtually any shape and permanently apply practically any color. This is why our windows company could offer up to 47 interior-exterior color combinations to match and enhance your existing décor.

Sustainability

The wood part of Fibrex comes from unusable pieces of Andersen windows. We never have to cut new trees to produce it. In fact, we’ve prevented the harvesting of nearly 90 million board feet of lumber since we first developed Fibrex.

Maintenance

Like our doors, our Fibrex-made windows are almost maintenance-free. They never need repainting or scraping, which you couldn’t always say about fiberglass units. It won’t decay or mold and guaranteed not to flake, blister, peel, crack, pit, corrode, or rust for 10 years from its original installation.

Reviews

"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!!"
