FAQs About Fibrex® Windows

Fibrex® is an exclusive thermoplastic-polymer-wood composite that combines the best qualities of wood and vinyl. Like wood, Fibrex is sturdy but doesn’t have as many maintenance needs, mainly thanks to its vinyl composition. Thanks to this exceptional durability, Fibrex windows resist a wide range of common issues such as blistering, peeling, cracks, rot and corrosion.

FAQs About Fibrex® Windows

What Are the Other Advantages of Fibrex Windows?

In addition to their exceptional durability and minimal maintenance needs, Fibrex windows also have excellent resistance against harsh weather, making them a smart investment for those living in temperate climates. Unlike other conventional window frame materials, Fibrex doesn’t expand and contract in response to abrupt temperature changes. Over time, repeated contractions and expansions in the window frame can damage the window sealing, which will, in turn, allow warm or cool air to leak out of your home and increase cooling and heating costs.

Remember: There’s no such thing as a one-size-fits-all approach in home improvement projects, and window replacements are no exception. To protect the returns on investment on your window, it’s important to choose a frame material that can handle your area’s climate.

How Long Do Fibrex Windows Usually Last?

To find out how long a Fibrex window replacement can last in real-world conditions, Renewal by Andersen® took out 10, 20-year-old Fibrex windows from customers’ homes. Despite prolonged exposure to wear and tear over two decades, the windows were still in good, working condition—the weather sealing wasn’t damaged and the opening mechanisms were working just fine.

How Energy-Efficient Are Fibrex Windows?

If you live in a temperate climate, it makes practical and financial sense to invest in an energy-efficient window replacement. After all, heat gain and heat loss through windows account for roughly 25% to 30% of household residential heating and cooling costs, according to the Department of Energy.
