VIDEO: HOW IS THE FIBREX® MATERIAL MANUFACTURED?

Video Fibrex Material Manufactured

The story of Fibrex® material began in the late 1950s when the Andersen® Corporation wasn’t completely impressed with vinyl. Although it was resistant to decay and painless to maintain, it lacked enough structural integrity with its high expansion and contraction rate.

Three decades and over 30 patents later, Andersen perfected the process to manufacture Fibrex in 1992. Fast-forward to today, Fibrex is the st andard material for Renewal by Andersen of St. Louis’s replacement windows. As its exclusive source in the region, we share how it’s made:

Reclaiming Unused Wood

Fibrex is made from 40% wood fiber by weight and 60% proprietary polymer. Its wood content comes from reclaiming and repurposing unused portions of Andersen wood window components. This is why our Fibrex material is environmentally smart, saving nearly 9 million board feet of lumber from harvesting since its first mass production.

Mixing the Ingredients

Our windows company heats the reclaimed wood fibers to extract all of the moisture. Once completely dried, we heat the polymers to a certain temperature before combining them with the reclaimed wood fibers. During this process, the wood fiber and polymer molecules bond and form a new compound. The liquid polymer fills and encases every individual cell of the wood fiber without crushing any of them. As a result, the process lends Fibrex wood’s superior rigidity and vinyl’s moisture repellence.

Molding Into Custom Components

The mixture then flows through an innovative extruder. It allows us to create Fibrex frames, sashes  and grilles in virtually any shape. This operation also applies any color of our customers request; in fact, we currently offer 48 different interior-exterior color combinations to bring all conceivable grille patterns to life.

Thanks to Fibrex, you can rest assured that Renewal by Andersen of St. Louis’s products will st and the test of time. One study reveals that our windows haven’t peeled or cracked, and have continued to operate smoothly even after 20 years of muggy Minnesota summers and rough winters.

Furthermore, Fibrex is also a sub-sill component of our hinged Frenchwood® doors, which has an extremely dem anding role. Because of its resistance to rot and decay and incredible strength, it fits the bill perfectly and performs exceptionally well.

"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!!"
