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.

Proven Strength

The facts prove it. Ultrex fiberglass is eight times stronger than vinyl and three times stronger than vinyl/wood composites. It resists fading, chalking, peeling and cracking, giving you unparalleled strength and durability. We’re constantly testing Ultrex to prove it’s the toughest window material available.

Built Tough

* “Life cycle assessment of windows for the North American residential market: Case Study” by the University of British Columbia Scandinavian Journal of Forest Research, 2008.

Our windows are Built to Perform® in the face of Mother Nature’s toughest elements. The Ultrex pultruded fiberglass that goes into every Integrity window and door remains stable in extreme temperatures and expands at nearly the same rate as glass, resulting in windows that are strong and true. Fiberglass windows have a 38% longer* useful life expectancy than vinyl.
