Fibrex® Windows: Stronger Than Vinyl, Better Than Wood

One advantage of vinyl replacement windows is their durability. Vinyl filled the massive gap left by the many shortcomings of wood-frame windows in terms of maintenance and longevity. For all its merits, however, vinyl has a few of its own disadvantages. The material is prone to warping when exposed to Tennessee’s hot and humid summers, causing problems in its operability and performance.

Fibrex® Windows: Stronger Than Vinyl, Better Than Wood

For the longest time, homeowners had to choose between the pros and cons of either vinyl or wood when it came to replacement windows. That is, until Andersen developed a material that has the benefits of both vinyl and wood, without their known limitations. They called this material Fibrex® and it has formed the backbone of many Renewal by Andersen® window replacements. Let our experts at Renewal by Andersen® of Memphis explain the qualities that make Fibrex a superior window frame.

Stronger Than Vinyl

Fibrex is a composite material made with real wood fibers combined with a durable polymer base. It was designed, developed, and implemented by Andersen in 1992 for use in all window and door replacement projects of their installation arm, Renewal by Andersen. Like vinyl, it possesses a rigid structure that resists many types of physical damage, including one that has plagued vinyl for the longest time: warping.

Better Than Wood

Wood fiber chips provide Fibrex with a natural wood grain that looks just as good as its parent material. It is infused with color right from production so Fibrex frames never fade and never need to be repainted. It also has very low-maintenance requirements than wood and can last decades before showing any sign of deterioration.

"This company is very well organized. Their representative was very well informed and spent a lot of time explaining every detail, in their process. They keep you informed, and you can tell, you get what you pay for!! I'm extremely pleased with the outcome. We have had "several" compliments from our neighbors. They have varieties of colors, and what a difference it made. Thank you...."
