4 Benefits of Our Exclusive Fibrex® Material Frames

Renewal by Andersen® replacement windows feature frames made of Fibrex®, a composite material that combines the best qualities of wood and vinyl. Here are the benefits of Fibrex:

1. Superior Strength: Fibrex frames are on par with traditional wood frames when it comes to strength and durability and are twice as strong as the best-quality vinyl frames. The unique combination of wood fibers and polymer make Fibrex resistant against the problems that plague typical replacement windows, such as warping, cracking and fading, as well as expansion and contraction due to weather changes. These qualities allow us to build slimmer frames that allow for larger glass areas.

2. Low Maintenance: Homeowners who enjoy the low-maintenance benefits of vinyl window frames will find the same benefits in our Fibrex frames. All you need to keep Fibrex clean is a garden hose and a soft brush. The colors and finishes are applied during manufacturing and will never require scraping or repainting. Fibrex frames are also warranted not to rot, decay or grow mold.

3. Exceptional Insulation: Renewal by Andersen replacement windows are some of the most energy-efficient replacement windows available thanks to Fibrex’s excellent insulating ability. Fibrex complements our High-Performance™ Low-E4® glass in minimizing heat transfer, which helps reduce your indoor heating and cooling requirements.

4. Responsible Manufacturing: The wood fibers in Fibrex are sourced from the wood trimmings at the facilities of our parent company Andersen. This waste wood is pulped, dehydrated and combined with polymers at a molecular level. Our replacement windows are tested for minimal volatile organic compound (VOC) emissions, which help reduce indoor air pollutants. Thanks to this, we are the only window company who has received the Scientific Certification Systems (SCS) Indoor Advantage Gold™ certification.

We use Fibrex to build all our replacement window styles, from double-hung windows to picture windows. Call Renewal by Andersen of Central Pennsylvania today at (717) 591-4900 or fill out our contact form to schedule a free, in-home consultation. We serve many areas in and near Harrisburg, PA.
