3 Excellent Things Fibrex® Windows Can Do for You

If you want to get the most out of your new windows, you’ll want to make sure they’re made of a quality framing material. And while there are many options available today, not a single one of them compares to Fibrex®, a revolutionary composite material used in our Renewal by Andersen® windows. Here are some of the great things to expect from this window material:

Fibrex® Windows

1. Keeps Your Home Safe and Damage-Free

Made from a strong blend of wood fibers and thermoplastic polymers, Fibrex can provide the strength and durability of authentic wood, allowing for replacement windows that remain impervious to weather damage. But unlike wood, Fibrex is impervious to moisture damage, so you can be sure that your new windows will be highly resistant to cracking, pitting, peeling, rot and corrosion. This composite material also retains its shape even when exposed to extreme fluctuations in weather and temperature, so warping and distortion won’t be an issue in your new windows.

2. Creates an Instant Focal Point in Your Home

Fibrex is so durable that we can shape it into any window style. In fact, its strength also allows us to design and create Renewal by Andersen windows with ultra-thin frames and a larger glass area. Once installed, they create an instant focal point that takes any room’s look to the next level, all while bringing more natural light into your Montana home to promote more effective daylighting. Did you know that Fibrex is as low-maintenance as vinyl? As a result, windows made of this excellent material require less effort in cleanup and maintenance. 

3. Improves Your Home’s Thermal Comfort

Here’s yet another thing to love about Fibrex – it creates strong, tight window seals that prevent air leakage and significant energy loss. Its superior insulating value is further augmented with our advanced High-Performance™ Low-E4® SmartSun™ glass, which reduces heat transfer into your home during summer, and prevents heat loss during winter. This allows for a home that remains consistently comfortable no matter the season.

"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. "
