The Many Advantages of Fibrex® Material for Windows & Doors


When choosing a contractor to work on your home improvement projects, it’s important to consider the quality of the products they use – material components, special features, price range and which manufacturer they represent. You see, no matter how good contractors are, if their products are inferior, then the goal of enhancing your house is defeated and your investment is wasted.

One product that lives up to the promise of delivering quality and cost efficiency is Fibrex® material from Renewal by Andersen. Here’s why.

Fibrex windows

Energy Efficiency

When you choose Renewal by Andersen window replacement, you’ll enjoy lower maintenance and increased energy efficiency. This is because of the energy-saving features of windows built with Fibrex material and the precise installation techniques used by our certified master installers. Lower-quality materials, such as vinyl, are susceptible to damage that can compromise energy performance, resulting in higher energy bills.

Security & Protection

If your window can withstand pressure and damage, then harsh weather won’t compromise its ability to keep you, your home and your family protected from harmful elements. Furthermore, the durability of Fibrex material will keep your windows functioning as they should.

Aesthetic Consistency

Durable Fibrex material never requires painting and will not crack, pit, corrode or rot1, leaving your windows looking brand-new for years to come. That’s because our exclusive Fibrex material stays strong, even after 20 years of exposure to severe hot and cold temperatures.2 This also allows us to offer dark exterior colors that many other companies can’t.

And Much More…

In addition, our Fibrex material features many other desirable qualities, including:

  • Superior insulating properties.
  • Environmental responsibility.
  • A quality warranty.
  • Strength.
  • Beauty.

As you can see, Fibrex material offers all the qualities you’re looking for in a window. In addition,  homeowners will be happy to know that Renewal by Andersen of Northeast PA also offers and installs stylish, durable patio doors to complement our windows.

"Our installation team, Josh and Mike, did a phenomenal job with the installation, cleanup, and "orientation" after the work was completed! We were totally satisfied with everyone that we dealt with before and after the installation...and would surely recommend Renewal by Andersen to anyone contemplating a window replacement project!"
