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.

"Excellent service and product! They checked in with me every few weeks while we were waiting for the order. I was impressed with Sam, who measured my windows and headed the installation crew. He was respectful and patient with his team. They cleaned up after themselves. Before the new windows I had huge windows that didn’t open. Now I feel much safer and get better temperatures in those rooms."

"My experience with Anderson Renewal was amazing! From the first meeting with Miranda to choose my windows and doors to the installation provided by Tim and his crew was a pleasure! I just bought a home built in the 1960's that needed new windows and a new double front door with sidelights. As everyone knows Anderson Windows are great, but it was the people I interacted with from Anderson that made it such a great experience. It took three days for the windows and door to be installed and they "worked" every minute they were here. My huge front door took most of the day to install because they had to put in a new header and other improvements to make it fit! They even put up new drywall on the inside. Many people in the neighborhood have stopped by to comment on my beautiful front door! I think the crew left my house cleaner than it was before they started! Constantly cleaning up after themselves. I am thrilled with my windows and feel lucky to have met the team at Anderson."

"Very professional staff . No pressure sales. The job they do is neat and clean, no cleanup left for the owner. Communication is great. Always informed on the status of of your product, AND the tin of cookies you receive afterwards is a pleasant plus."
