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.

"I just bought my first house. My patio sliding door was rotten. So, I needed it to replace it. Renewal by Anderson of Southern Missouri listened to what I wanted and delivered it. They did a fantastic job of installing and cleaning up afterwards. They did it even in freezing rain that day I was scheduled to have it replaced. They even had a follow-up to check things out and do the touch ups. I'm amazed at there work. Great job Renewal by Anderson."

"On Feb 1,2024 my husband and I selected Renewel by Andersen for windows for our entire house. It made our house more beautiful with the picture windows. Made the outside more attractive, and on the inside. We did 14 windows. We had 4 men come to do the job in 1 day And they were very friendly, efficient,fast and cleaned up inside and outside perfectly. And most importantly we noticed the heating furnace runs less,therefore saving us money on our gas bill. We live in SW Missouri. We recommend anyone who wants to replace windows in their home to pick Renewal by Andersen. Sincerely, Darius and Nancy Durman"
