Integrity Windows

WHY CHOOSE INTEGRITY?

Integrity windows and doors are made with Ultrex®, a pultruded fiberglass we’ve patented that outperforms and outlasts vinyl, roll-form aluminum and other fiberglass composites. We use Ultrex and our proprietary pultrusion process to manufacture high-demand windows and doors that endure all elements without showing age or wear.

Our values and work ethic are forged by the communities where we’re proud to live and work. When you choose Integrity windows and doors, you support a small-town, family-owned and operated company with deep roots in the community; some Marvin employees are fourth-generation, following the family tradition. We share profits with our employees; we support our communities; we treat our dealers and customers fairly and with respect. That’s Integrity.

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.”
