The Integrity brand is Built to Perform®. Their 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.”
