Integrity®

Integrity® Windows and Doors was born from The Marvin® Companies’ century-long heritage of service, craftsmanship, and quality with a focus on all-out performance. We’re proud to manufacture the most innovative fiberglass windows and doors on the market, backed by top-notch customer support and incomparable value.

We build windows and doors with Ultrex® pultruded fiberglass exteriors paired with either rich wood or Ultrex fiberglass interiors for a long lasting, virtually maintenance-free window and door solution. Every Integrity product is available with a wide variety of options to suit your home’s design, including energy efficiency solutions for every climate.

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.
