Why Choose the Marvin Family of Brands?

The people that make up the Marvin Family of Brands are dedicated to enriching the places we live and work. What began as a family company built on an old-fashioned code of honesty, hard work, and service to their neighbors is now one of the world’s premier window and door companies. Through our three unique brands—Marvin, Integrity, and Infinity—and each brand’s unique offerings of customization and performance, we can provide a solution to any project. For everything from new construction to remodeling and replacements, to commercial building and even historical restorations, we never take shortcuts, and we always adhere to the highest possible standards and the highest levels of service. We stand behind every one of our products, every step of the way.

We make it our priority to be a partner to our customers through every step of the process, and go above and beyond what is expected. That includes making sure our products continue to live up to our high standards every single day.

Integrity’s Story

The Integrity brand is Built to Perform®. Our products, made with Ultrex® pultruded fiberglass, feature the industry’s first and only AAMA verified 624-10 finish. Ultrex outperforms and outlasts vinyl, roll-form aluminum, and other composites. Superior material performance and unmatched fast, efficient delivery make Integrity windows and doors a great overall value.
“At Integrity from Marvin, we didn’t join the fiberglass window and door industry, we pioneered it. In 1994, Integrity was born from The Marvin Companies’ century-long heritage of service, craftsmanship, and quality with a focus on all-out performance.”
