The Benefits of Fibrex® Windows

It’s a great time to upgrade your old windows and you’ll find an abundance of choices for replacement windows. From sliding windows to custom windows, different kinds of window styles are available to meet your specific needs. And when it comes to window materials, Fibrex® is definitely one of the best options out there. Below are some of the qualities that you can expect from Fibrex windows.

Benefits of Fibrex® Windows


Fibrex windows are twice as strong as vinyl windows. They remain weathertight in various weather conditions, and they can stand up against extreme temperature swings. With Fibrex windows, you don’t have to worry about high expansion and contraction rates, which could lead to bowing, cracking and damage to the glass seal. Due to their excellent durability, Fibrex windows can last longer than your typical vinyl windows.

Maximum Glass Area

Fibrex windows have narrower frames, allowing you to have a larger glass area and a bigger view of the outside. If you want to make the most of your window replacement project and ensure that your new windows will make a difference to your home’s aesthetics, these windows won’t disappoint you.


Fibrex has insulating properties that are 700 times better than aluminum. And to maximize this quality, experts recommend pairing it up with Andersen’s High-Performance™ Low-E4® glass. With this combination, your windows can prevent heat loss in the winter and keep your indoor space cool in the summer — ultimately ensuring superior comfort inside your home all year round.

"I highly recommend Renewal by Andersen. We were treated well and everything went smoothly from start to finish. The company kept in contact with me before, during, and after the installation and let me know what to expect. I'm in love with my new windows! I will be using this company again when we refinish our basement. "
