Why Choose Renewal By Andersen For Your Window Replacement Part 2 Our Innovative Product Features

Renewal by Andersen wants only the best for you, and we give you what you deserve through state-of-the-art technological strategies. Two of the most well-known features we’ve exclusively created are Fibrex® and High-Performance™ Low-E4® glass. We discuss them in more detail below:

Fibrex® Composite Frames

Every window product we install features our exclusive Fibrex composite frame. This highly durable, versatile material is composed of clean, recycled wood fibers, saving millions of square feet of lumber annually. This means Fibrex is one of the most sustainable frame materials there is on the market. Since it’s made by combining two materials, Fibrex brings to the table the natural charm and durability of wood with the low-upkeep properties of vinyl. You can expect this material to last long even though it usually gets exposed to harsh weather conditions. In addition, it boosts insulation, helping keep the ideal temperature inside your home all year round.

High-Performance™ Low-E4® Glass

When you choose our windows and doors for your upgrade, you can enjoy higher energy savings – as much as 25% off of your bills every year! This is because all our products come with our cutting-edge High-Performance Low-E4 glass, which works to keep your interior temperature pleasantly warm during winter and refreshing in summer. Since you don’t have to rely significantly on your HVAC systems to regulate your interior temperature, you can expect lower energy consumption over time. In addition, this glass package helps minimize the effects of harmful ultraviolet (UV) rays, protecting your furnishings from the bleaching effect of the sun.

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
