Engineered for Performance, Designed for Your Home

Renewal by Andersen® windows and doors are more than just beautiful—they’re engineered for performance. Every product is crafted with advanced materials for durability, energy efficiency and long-term value. 

At the heart of each window is our exclusive Fibrex® composite material, a unique blend of wood fiber and polymer that combines the strength and stability of wood with the low maintenance of vinyl. Fibrex material never requires painting and will not crack, pit, corrode, or rot, even in extreme weather, and it’s proven to stand up for decades without losing its shape or beauty. That means less maintenance, better energy performance, and windows that look just as good as they perform. No other company sells Fibrex material, making it truly unique to Andersen Corporation.

During product development, our team puts every design through rigorous testing to make sure it meets—or exceeds—industry standards for strength, efficiency, and weather resistance. Because each window and door is custom-built to your home’s exact measurements, you’ll enjoy a perfect fit.

How Long Do Renewal by Andersen Windows Last?

Some of the best replacement windows should continue to operate smoothly and maintain their appearance for decades when they're properly design and installed. After 30 years, Renewal by Andersen windows are still easy to open and close.‡

Recently, we pulled a batch of our original windows from the home they had been installed in more than three decades ago. That’s more than 20 years of extreme Minnesota weather—bitter, brutal winters; hot, muggy summers.

And what did we find? After all those years of enduring Mother Nature’s mood swings… they passed our battery of performance tests with flying colors. After three decades in a real family home, facing real Minnesota weather—bitter, brutal winters; hot, muggy summers. They still looked brand new, and they still opened and closed as easily as the day they were installed.‡
