At Integrity from Marvin, they didn’t join the fiberglass window and door industry – they 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 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.

In 2000 Alliance Vinyl Window became a founding member of the American Window Alliance (AWA). The AWA is a network of regional manufacturers who produce and market the same product under the same brand name. Thus was born a new brand of vinyl windows and patio doors called Alliance Window Systems. The AWA network of independent manufacturers offer its customers the strength of a national network with local support capable of providing the highest level of service to our customer base.
