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.

"This was one of the best experiences I've ever had with a company. I ordered the windows in November and was told they wouldn't be here until July. That kind of delay the new norm so I wasn't a bit upset with the timeline. I was given an early present when they called to say the windows would be in at the beginning of May. We agreed on the week of May 16th to do the installation, there were 30 windows and a sliding door to install. They arrived promptly on their scheduled install date, and got straight to work. By the end of day one, they had all the upstairs windows complete and their work was incredible. Day two came with more of the same, the crew showed up promptly, got straight to work, and when they left they had every window downstairs installed. The third day they again arrived on-time, and got to work installing the door. The door and windows are perfectly installed. The two lads that did the installation did a phenomenal job, and were friendly to boot. I would give them more business if I had any :) The service I received from the company was great. They kept me abreast of anything that was going on with my order. I appreciate my concierge, Christina, she was good at communicating timelines and getting everything scheduled."

"The two installers were great! They were polite and hard working and they cleaned up all the outside and inside. It was like they were never here. As for the windows, I love them, not only looks great, they are efficient. Now every window in my home has Renewal by Anderson."

"We had the pleasure recently of having Andersen replace all of our windows. From the very first interaction with the office personnel through the completion of the project, they have been nothing but professional. From Brian our sales rep to Christina the appointment scheduler, they were a pleasure to interact with. Installers Keith, John, and Evan were fantastic to work with. They went above and beyond to repair an area which was slightly damaged during the removal of a window...caulked and painted it. They took extra precaution to ensure the floors were covered while working inside and cleaned up each day inside and out. We love the look of our new windows and can't wait to enjoy the savings in utilities they'll provide. Thanks so much Renewal by Andersen!!"
