Spotlight on Material: How Well Does Fibrex® Age?

Do you wonder why some windows last for a longer time than others? Maybe, you’ve noticed how some windows don’t seem to age as much. While there are many factors behind this, the window material has much to do with a unit’s longevity.

Fibrex® as a Superior Material

Fibrex® is a revolutionary composite material, which has the strength and durability of wood combined with the low-maintenance features of vinyl. Because of this, Fibrex makes our windows incredibly strong and efficient. The good news is that Fibrex ages graciously. Our durability test on our windows that have been used for 20 years shows that they are still functional and solid years after installation. The lab tests performed also proved that there were no cracks, peels or chipping parts.

Fibrex as an Excellent Window Material

In addition to durability and longevity, Fibrex is also energy-efficient. Its first-rate thermal features combined with High-Performance™ Low-E4® glass result in an excellent energy-efficient window. You can expect your energy bills to be lower without having the need to endure the heat in summer or cold in winter.

A Low-Maintenance Window Replacement

Our Fibrex window frames do not need repainting or scraping because they won’t rot, crack, peel or corrode. This means that you don’t need to worry much about maintenance, and you will be sure to maximize your investment.
