Advantages of Fibrex® Material



Fibrex® material is a revolutionary window frame material that is exclusive to Renewal by Andersen. Using Fibrex®, Renewal by Andersen produces durable, energy efficient windows that combine the strength of wood and the easy maintenance of vinyl.

Fibrex® material sets itself apart from all other window materials from the moment production starts. Unlike the production processes of wood or vinyl, which leave tons of excess material that just ends up in a l andfill, Renewal by Andersen’s exclusive Fibrex® material frames and sash contain 40% reclaimed wood fiber by weight. Much of the wood fiber used to make this exclusive Fibrex® material is reclaimed from Andersen Corporation’s wood window manufacturing facilities. This eliminates the majority of waste and allows for a far more sustainable product.

The product itself is a composition of wood grain and thermoplastic polymer. This combination makes for an extremely efficient material, one that blocks thermal transfer 700 times better than aluminum. This helps your heating and cooling systems work only as directed and limits the amount of energy needs to keep your home at a comfortable temperature.

Further setting itself apart from wood, vinyl, or aluminum, Fibrex® offers a beautiful aesthetic that will not be tarnished by mold, mildew, rot, chipping, warping, or corrosion*. With limited annual maintenance, your Fibrex® windows will look factory fresh for years to come.

"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."
