How Our Unique Fibrex® Material Is Manufactured

At Renewal by Andersen®, the frames of our windows are made of our unique Fibrex® material. This composite frame has the strength of natural wood but with the low-maintenance benefits of vinyl. It’s also twice as strong as the latter material.     

Your local window replacement service provider shares more about the manufacturing process of Fibrex material. How Our Unique Fibrex® Material Is Manufactured

What is Fibrex Material Composed Of?

Andersen manufactures millions of windows each year. Miling intricate profiles in the windows produce wood pieces that are not big enough to be used in other window components. The unused wood is reclaimed and repurposed to create Fibrex material, which is made up of 40 percent wood fiber by weight and 60 percent propriety polymer. 

The wood fiber is heated to make sure it’s free from moisture. After it has been dried, the polymer is heated to a certain temperature and then combined with the wood fiber. When the right amount of pressure is applied to the liquid polymer, it encases and fills every cell of the fiber. The wood fibers then align and bend together, which allows Fibrex to resist moisture and have superior durability. After this, the compound goes through an extruder so it can be made into any shape and applied with virtually any color. 

What Are the Benefits of Fibrex?

Renewal by Andersen is a window company known for its superior products and excellent workmanship. We test each window frame and make sure they are in perfect condition before it’s brought to your home. 

Fibrex can withstand extreme weather conditions and weather changes. The wood fiber help in insulating the material to minimize heat loss in winter and heat gain in summer. Together with our special glass packages, you’ll have windows that can help make your home comfortable and save up to 25 percent on your energy costs.

"Absolutely wonderful experience working with renewal. They kept my wife and I up to date all throughout the process from the initial sales pitch to installation. They were courteous and professional throughout. The installation of 8 windows was completed in one day and the product is fantastic. Immediate difference felt inside the home and its much quieter now too. My wife and I are thrilled at our purchase. The windows are a bit pricey but worth every single penny. Wonderful product from a wonderful company. Will definitely be using them in the future to install the rest of the windows in our home."

"When I say, superior service I mean just that!! From start to finish I was pleased!! Step 1, Scheduled appointment at the Home show… easy. Step 2, phone call to confirm appointment the next week….easy. Step 3, in home consultation with Keith Billingsley…..Amazing!!!! Step 4, call and cancel all other Window companies and let them know you have chosen the Best company, Anderson Windows!!! My Windows took a couple of months to come which was not a problem. Oooohhh but when installing day came ( a week early) I was lost for words. The installation team was A1 with professionalism and cleanliness!! They didn’t leave a scrap of trash on my property. It was cleaned up both days. I had Ed Tutton and crew. I had a million questions and they answered every one of them and made me feel so assured with the process. A couple of my Windows had wood rotted. They took care of it and fixed it better than when the house was built!!! Two of my Windows came in broken, it was addressed and shown to us and reorder in the same day!! They will be installed later. The Windows are so beautiful I stood in my master bedroom Windows for almost 3 hours just looking out. I hate Window grates…. I have solid glass Windows now❤️❤️! I wish I would have ordered my new front doors from Anderson Windows. So if you are looking to get new Windows you must go with Anderson Windows!!!"
