A Quick FAQ About Fibrex® Replacement Windows

You’ve probably heard this before, but material does matter when it comes to choosing new windows for your home. Traditional window materials include wood and vinyl, but if you’re looking for something tougher and much better, you can never go wrong with Fibrex®, a composite material used in Renewal by Andersen® windows. To learn more about Fibrex® replacement windows and how they can benefit you, check out this FAQ:

Replacement Windows

  • What exactly is Fibrex®? As mentioned before, Fibrex® is a composite material. To be exact, it’s made of wood grain and a thermoplastic polymer that allows it to provide the superior durability and insulating properties of wood–but none of its weaknesses. Windows made of Fibrex also require little maintenance, just like their vinyl counterparts. But the resiliency and stability of Fibrex® replacement windows when exposed to extreme weather and temperature make them the better and longer-lasting choice.

  • Are Fibrex® windows customizable? Picking the best color combination is almost half the fun in a window replacement. Fibrex® windows undergo a unique fabrication process that blends the color of your choice with the composite material, allowing for a lovely, consistent and fade-resistant finish. Once you’ve decided on the color, you can deck out your new Fibrex® windows with a hardware finish and grille pattern. 

  • How strong are Fibrex® windows? Incredibly strong. Fibrex® replacement windows don’t crack, pit, or corrode. They are also impervious to rot and warping–a common problem in wood and vinyl windows. Because Fibrex® windows resist fading and peeling, they only need the occasional cleanup and maintenance to keep them looking great. What’s more, Fibrex® composite itself is so durable that it can be shaped into any window style, while also allowing for slimmer frames and a larger glass area.

  • What about energy performance? No worries–Fibrex® windows can help lower your energy costs. When closed, they create a tough, airtight seal that prevents significant energy loss. And if paired with our advanced High-Performance™ Low-E4® SmartSun™ glass, you get to benefit from some of the most energy-efficient windows available today.

"I was very impressed with Renewal by Andersen. They showed up in time and we received several follow up phone calls as the installation was being done as well as the sales representative stopping by to check in on the installation. The delivery/ installer was very professional. I would highly recommend Renewal By Andersen."
