Renewal by Andersen® Replacement Windows Stand the Test of Time

Fibrex Window Design

On Renewal by Andersen’s twentieth anniversary, a 20-year durability study was performed.* One look at the results will tell you why our replacement windows are a very wise investment!

Sustained Durability

Over long periods of time, vinyl windows tend to bow and crack, while wood windows are subject to fungal growth and rot. We wanted to find out how Renewal by Andersen® windows held up in comparison. For the study, we removed 10 sets of double-hung windows that had withstood 20 years of harsh weather conditions and extreme temperatures in the northern U.S.

You might have expected our windows to perform similarly to wood, vinyl or aluminum windows – but this wasn’t the case! In fact, the results blew the competitors out of the water. Even after 20 years, the test windows made of our unique Fibrex® material stood the test of time, with no signs of chipping, cracking or peeling.

Long-Term Energy Efficiency

Windows from Renewal by Andersen are incredibly energy-efficient. Unlike vinyl, our strong Fibrex material has a low expansion rate, which means it’s less likely to buckle and crack, a process which can break the glass seal and allow water to leak in and air to leak out. Our Fibrex frames, paired with the impressive insulating properties of our High-Performance™ Low-E4® SmartSun™ Glass with HeatLock™ Technology, result in windows that help decrease your energy bills by keeping your house cooler in the summer and warmer in the winter. Low-E4 SmartSun Glass used in combination with the HeatLock interior coating offers near triple-pane performance in a dual-pane window!

As shown by our study, even after years of being buffeted by wind and rain and subjected to the highs and lows of fluctuating temperatures, Renewal by Andersen windows won’t chip, crack or peel. In fact, they operate just as smoothly after 20 years as the day they were installed! Plus, Renewal by Andersen windows are installed by certified master installers and backed by the best warranty in the business.

"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!"
