4 Advantages You Can Expect From Fibrex® Windows

In 1992, Renewal by Andersen® perfected and patented the Fibrex® technology, a composite material that blends the stability of wood and easy-care features of vinyl replacement windows. In this article, we will reveal several reasons why Fibrex is the better framing material for replacement windows.

Fibrex® Windows

1. Strength: Since it is a composite material that uses real wood fiber, it is extremely strong and durable. This also means narrower frames, which, in turn, provides a greater area for glass. On the other hand, window frames made of vinyl are usually thicker in size, cutting back its glass area and known to have a higher expansion/contraction rate.

2. Insulation: If you are looking for windows with superior thermal insulation properties, Fibrex is the perfect choice. When combined with Andersen® High-Performance™ Low-E4® glass, it keeps your home warmer during chilly weather and cooler during hot temperatures. Not only does this make your living environment comfortable year-round, but it also saves money on monthly energy bills.

3. Low-Maintenance: Fibrex is a low-maintenance composite that does not expand and contract easily even with extreme temperature changes. It never needs to be painted or scraped and will not rot or decay. Other materials like vinyl may need frequent maintenance throughout its lifespan.

4. Beauty: Renewal by Andersen replacement windows come in a variety of shapes, lines, sizes, and designs. The extruded Fibrex material can be made into traditional casements and curved specialty windows and complement any architectural style. Other windows on the market have square profiles that may appear artificial in your home.

"Our windows were the original ones that were installed when they built the house in 1972. They wouldn't open, they had been painted shut. They were single pane and the glaze was cracked everywhere. I had to put plastic up every year to help keep the house warm at least a little bit. My MIL was surprised that there weren't any panes in the windows. Now she loves it. We have put a film on the windows so we can see out but no one can see in. We are loving it!"
