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.

"Work was performed by a professional installation team in a very efficient and non-obstructive manner. They cleaned up after themselves and left us in a better condition than it was before they started. I would definitely use Renewal by Anderson again."

"We have had Renewal by Anderson replace windows before so we knew how special the company was. The job the installers did was absolutely perfect. I will contact them again for more windows and will highly recommend them to friends and family. Thank you so much!"
