Fibrex® - Only The
Best For Your Windows

The strength of wood with the low maintenance of vinyl

Ready for a window that gives you the best of both worlds, between vinyl and wood?  Andersen Corporation’s tradition of innovation led to the invention and patenting of Fibrex® material. Now, after more than 30 years of development, Fibrex® material is in a class of its own. It looks better, lasts longer, and performs beautifully!

With the strength of wood and the low maintenance of vinyl, Fibrex® material is an energy efficient insulator and offers design capabilities unlike any other window framing material. We provide Fibrex® material in 27 custom colors, including dark tones that vinyl can’t offer. Since you’ll never have to worry about scraping and painting, Fibrex® material will give you additional peace of mind. Even better, Fibrex® material is proven not to flake, rust, blister, peel, crack, pit, or corrode.*

Along with color, design, and lifestyle benefits, the environmental benefits of Fibrex® are unmatched. Andersen Corporation has earned many environmental certifications for leadership in reclaiming and reusing materials and preventing harmful off-gassing in indoor environments.

What if the products you use every day could make the planet healthier? And what if they could save you money in the process? Andersen Corporation’s heritage includes a long-standing commitment to energy efficient products and environmental stewardship. Andersen, including Renewal by Andersen, recently earned ENERGY STAR®’s Partner of the Year award.

Why is Fibrex® Better Than Vinyl?

How did we develop a product that combines the best of both worlds for your replacement windows? Fibrex® material is 40% wood fiber and 60% thermoplastic polymer. It has twice the strength of vinyl, making it resistant to damage from any sort of climate.** The weathertight seals stay firm and closed, keeping your home a comfortable temperature. It does not rot, decay, peel, or flake, which keeps it low maintenance. Since the color is part of the product and not painted on, it stays vibrant and beautiful for years to come.

Fibrex® material is a better window framing material for several reasons:

  • Because it is a composite using real wood fiber, it is very strong. This means narrower frames which, in turn, means more glass area. Vinyl frames are often thicker, reducing glass area.
  • As a low maintenance composite, it expands and contracts very little, even with extreme temperature swings. That’s why we’re able to offer dark exterior colors, which will cause vinyl to warp in the heat.
  • Due to this material difference, Renewal by Andersen can offer one of the best window limited warranties in the industry.***
