Getting rid of your old windows and installing new ones is something you should only have to do once or twice in your lifetime. Thankfully, when you invest in top-notch replacement windows from Renewal by Andersen®, you can rest easy knowing your new units will provide superior durability and performance for years to come.
For over 100 years, Renewal by Andersen has been making high-quality windows. We have constantly striven to improve our products by leveraging new technologies and reinventing our processes. The culmination of all these efforts is our patented Fibrex® frame.
What Is Fibrex®?
Perfected in 1992, Fibrex was invented to combine the structural integrity of wood with the low-maintenance features of vinyl, resulting in a frame material that provides unmatched longevity. Don’t just take our word for it, though.
We conducted a long-term durability study back in 2015 to examine how our Fibrex windows had held up after enduring 20 years of Minnesota’s harsh winters and summers. The results speak for themselves.
Unparalleled strength – Even after 20 years of constant exposure to extreme weather, Fibrex had maintained its weathertight seal, unlike vinyl products that easily crack due to intense conditions. Fibrex is 200% stronger than vinyl, which is attributed to its low expansion and contraction rate.
Great aesthetics – Fibrex is made from 40% reclaimed wood by weight, which primarily allows it to incorporate the timeless beauty of wood. Unlike wood, though, our Fibrex windows are resistant to decay. As per ASTM E2068, our study revealed that our units displayed no signs of peeling or chipping 20 years after installation.
Consistent performance – Unlike other frame materials that easily bow or break due to changes in temperature, Fibrex remains stable. We are so confident about the state-of-the-art features and performance of our windows that we back them up with stellar warranties against manufacturing defects and workmanship issues.
