WHY CHOOSE INTEGRITY?
Integrity windows and doors are made with Ultrex®, a patented pultruded fiberglass that outperforms and outlasts vinyl, roll-form aluminum and other fiberglass composites. Ultrex and its proprietary pultrusion process are used to manufacture high-demand windows and doors that endure all elements without showing age or wear.
Integrity's values and work ethic are forged by the communities where they’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. They share profits with their employees; they support their communities; they treat their dealers and customers fairly and with respect. That’s Integrity.
