How Long Do Renewal by Andersen® Windows Last?

Key Takeaways

  • Renewal by Andersen recently conducted a study on windows that were in a home for 30 years, and found that Fibrex® composite material still performs just as well as it did three decades ago.*
  • Fibrex material stays twice as strong as vinyl and resists cracking or rotting after decades of extreme weather exposure.
  • Maximize your energy savings with High-Performance Low-E4® SmartSun™ glass. This advanced glass blocks 95% of harmful UV rays while reflecting heat to keep your home comfortable year-round.

When you're investing in new windows for your home, you want to know they'll stand the test of time. After all, replacing your windows isn't something you want to do every few years. Luckily, Renewal by Andersen® windows and doors are built to last. Let's explore what makes these windows so durable and how you can make the most of your investment.

The 30-Year Durability Study: Proven Performance

Here's something remarkable: Renewal by Andersen recently completed a 30-year durability study (an update to our 20-year study) that proves just how well our windows hold up over time. We took six windows that had been installed in a home 30 years ago, brought them back to our facilities, and performed rigorous testing on them. These windows fared through three decades of brutal Minnesota winters, scorching summers, and everything in between.

The results spoke for themselves. Our exclusive Fibrex® composite material continues to withstand temperatures up to 150°F after 30 years in a home.* Even more impressive, the Fibrex material was just as strong as Fibrex material made today—still two times stronger than vinyl after all those years.**

After 30 years in a real home under real conditions, the Fibrex material showed no cracking, rotting, pitting, corrosion, flaking, blistering, or peeling.* It met its design-intended performance metrics and stayed strong through decades of exposure to severe hot and cold temperatures.** That's the kind of durability you can count on.
