How Well Does Fibrex® Age?

Quality windows last longer and add more value to your home. Just like the other areas of your home, windows should be maintained regularly. They do not only add beauty, but increase energy efficiency as well.

As a  windows company, Renewal by Andersen® of St. Louis has innovative new materials with which to make window frames. Our patented Fibrex® framing material, for one, is a composite that combines the strength and stability of wood with the low-maintenance qualities of vinyl. It is an eco-friendly material, made from 40% recycled wood fibers and 60% polyvinyl chloride (PVC).

Why Choose Fibrex®?

Fibrex lasts a long time, and it is two times stronger than vinyl. We ensure that all our windows are tested to make sure they don’t contract and expand due to changes in temperature.

But how do we test these windows? We do tests on-site and more specific tests in the lab. Even after 20 years, Fibrex frames will experience no cracks or peeling, and will remain easy to operate. 

Replacement windows from Renewal by Andersen are made of Fibrex. They are strong and operable and proven to perform well regardless of their age.

Apart from the Fibrex material, our windows also come with our High Performance™ Low-E4® glass that reduces heat transfer. Get started with your new window and doors project today by calling Renewal by Andersen of St. Louis at (314) 332-2364, or fill out our online contact form to request an estimate. We serve clients in Missouri, including Chesterfield.

"I'm getting ready to do my 2nd round of window installation with Anderson Windows. I really appreciate the great financing options that they offer! They have top notch sales and installation experts who are very kind and considerate of their customers' wishes. The windows I have installed look great and I am so excited to get the next group of windows put in. My house looks so much brighter with my new windows. I definitely recommend Renewal by Andersen of St. Louis."

"We recently contracted with Renewal by Andersen to replace 5 windows in our home. First of all, we were very delighted that the time from contract to installation was less than two months. Joel and Craig arrived precisely at the agreed-upon time and spent less than four hours from start to completion of installation, including time to demonstrate opening/closing the windows and any questions we had. We were very pleased with the knowledge and professionalism of Joel and Craig, and, of course, we’re very pleased with the windows and how nice they look. We definitely recommend Renewal by Andersen."

"I replaced my front door and several windows. The install team did a great job with installation and clean up. Even covered floors and stairs. The team was very courteous and did a very professional job. Now our windows look great and we love our new door. I would recommend Renewal by Anderson in a heartbeat."

"We had a wonderful experience with Renewal by Anderson of St. Louis. From sales to office staff communication to installation everything was great. Our new windows are great quality, look amazing and improved the overall look of our house. We had four installed in August and will definitely be purchasing from Anderson for the rest of our windows in the future. I highly recommend! ❤️ Now it just needs to cool off outside so I can open them. 😃"
