Top 4 Advantages of Fibrex® Windows

Fibrex®, a patented and exclusive framing material by Renewal by Andersen®, is a composite that combines the low-maintenance features of vinyl and stability of wood. Today, we discuss the four amazing benefits of the revolutionary Fibrex windows.

Fibrex® Windows



  1. Energy Efficiency
    Our Fibrex windows have superior thermal insulating properties that allow homes to stay cooler in the summer and warmer in the winter. When you switch to energy-efficient windows, you will also see a difference in your monthly utility bills, helping you save a significant amount of money in the long run.

  2. Strength and Durability
    As a composite material, Fibrex is twice as strong as vinyl. Fibrex windows also come with a weathertight seal that can maintain its rigidity under extreme temperatures, making your home more resistant to severe weather and its after effects all year round, something that even the best vinyl replacement windows on the market cannot deliver.

  3. Beauty
    The strength of the Fibrex material translates to narrower frames; and narrower frames means expansive areas for glass and, therefore, more view. Moreover, the extrusion process in manufacturing allows the windows to be formed into any shape. This means that no matter your personal style or the architectural design of your home, you can easily find a Fibrex window that can complement it.

  4. Minimal Maintenance
    Renewal by Andersen windows are warranted not to flake, peel, crack, rust or corrode. These top-notch windows can stand the test of time and, with proper maintenance, remain beautiful and functional for up to 20 years.

"When we purchased the windows at the end of February we had been informed the lead time would be middle of August for installation. I was okay with this as they had been straight forward about the time frame. As the process moved forward I was kept informed via email at the various stages. I had received an email at the email of May stating the windows have finished being built and we can schedule installation. I was thrilled to have them be installed by the end of June. The installers showed up on time had been very courteous while performing the installation. They had scheduled 4 days for the installation and had completed it within 3 days. There was an issue with our front door as it was on back order and they brought out the wrong door by mistake, however they installed a temporary door until our door arrived and then came back out and installed the new door. I would highly recommend them to anyone needing replacement doors and or windows."

"A phenomenal removal and replacement of our front door. The installers were very detail oriented and very meticulous. This was the second time we've had doors replace with Renewal by Andersen of SW Missouri and both time our expectations were exceeded."

"The replacement windows are great quality and look great! The windows we are slowly replacing are original to the house, and are Andersen windows that are 40± years old! Our installers are the best! They went above and beyond what was expected of them. I highly recommend!! A+"
