VIDEO: Fibrex: Helping Windows Stand the Test of Time

If you plan on pursuing new windows for your home, be sure to obtain replacement units that can offer long-lasting performance. An integral part of this decision process involves choosing the right window frame material. Though various options like traditional wood and standard vinyl are widely popular, they pale in comparison to our exclusive Fibrex® material.

Notable Qualities of Fibrex

This exclusive material combines the strength and insulating features of wood with the low-maintenance qualities of vinyl. Fibrex doesn’t crack, chip, corrode or pit, and the frames and sashes of our windows are guaranteed not to warp or change shape even when exposed to extreme fluctuations in temperature, thanks to low thermal expansion rates. In addition, the material never requires painting or staining, which further helps maintain the beauty of our windows through the years.

Tried and Tested

Our composite replacement windows frequently undergo a series of tests, one of which is a long-term durability study. Here, we removed some of our windows from a customer’s home after 20 years of use. Tests were conducted on-site and in the laboratory to further support the study.

The study yielded astounding results. Even after 20 years of exposure to harsh weather and temperature changes, the windows remained strong and easy to operate, with no signs of cracking, peeling or chipping found. Truly, our Fibrex windows can stand the test of time!
