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.

"I can't say enough about Renewal by Andersen. From our initial sit down with the salesman to the final touches being put on our new windows, the whole experience was great! The windows look amazing & the installers were very careful to keep everything clean & cause minimal disruption in my home. Yes, they may be a little expensive, but you pay for what you get. These are quality windows installed by trained professionals. Communication was great & time frame was faster than i expected. They really deliver! I literally had nothing to worry about accept writing the check. I would strongly recommend this company to others! And I'll be calling them back out in the Spring to replace the last 3 windows on my house!"
