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.

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.”

The Infinity brand is Built for life®. Infinity Replacement Windows was created in 2002 when we recognized an opportunity to offer high-quality fiberglass replacement windows and doors for discerning homeowners, that are professionally installed by retailers. Our products are made of Ultrex fiberglass and were designed by Marvin experts to replicate the look of traditional wood windows while providing modern features and low maintenance. The combination of superior materials, design experience, and professional installation has resulted in a product line of high performing, energy efficient, and long lasting windows and doors.
