The Marvin Family of Brands is dedicated to creating products that make the places where we live and work more meaningful.
Marvin® Windows and Doors brings its Built Around You® philosophy to life with every customer and every solution. A premier manufacturer of made-to-order wood and clad wood windows and doors, Marvin offers the industry’s most extensive selection of shapes, styles, sizes and options to fit the diverse needs of builders and match the personalities of homeowners. Marvin’s tradition of delivering the finest craftsmanship in windows and doors began in Warroad, Minn., a small town just six miles from the Canadian border, where the privately-held, family-owned and operated company is still headquartered today.
Marvin® products truly have the power to transform the spirit of a room. The flexible design platform means that Marvin fits into a contemporary home just as well as it does into a historic commercial renovation. Recent product introductions like the Next Generation Ultimate Double Hung with an innovative hardware system, narrow checkrail and 100 percent wood interior; and the Ultimate Multi-Slide Door, available up to 50 feet wide and 12 feet high show that Marvin never rests on its laurels, but is continually leading the industry, setting new standards and delighting customers.
Integrity® Windows and Doors is the world’s largest and most experienced manufacturer of windows and doors made with Ultrex — a state-of-the-art pultruded fiberglass material. We didn’t just join the fiberglass revolution — we pioneered it. Our heritage as part of the Marvin family of companies is built on more than a century of excellence and expertise. Based in Fargo, N.D., Integrity offers a comprehensive line of window and door products that are Built to Perform® and backed by first-class customer service.
Ultrex® is eight times stronger than vinyl, three times stronger than vinyl/wood composites and as strong as steel. Ultrex fiberglass leads the industry in third party finish ratings. Ultrex, with its patented finish, is the first and only fiberglass finish to be verified to any of AAMA’s 624-10 finish specification for fiber reinforced thermoset profiles (fiberglass). This means Ultrex can be counted to resist fading, chalking, cracking, and peeling to keep your home looking great for years to come. And with new products like the Wood-Ultrex Insert Casement and Double Hung, and the Wood-Ultrex 4-Panel Sliding French Door, Integrity can enhance the look of any home or building.
Whether it is new construction, remodeling, replacement windows and doors or historical restoration, Marvin never takes shortcuts and always adheres to the highest levels of service. We make it our priority to be a partner to our customers through every step of the process, and go above and beyond what is expected. Both Marvin and Integrity stand for a century’s worth of heritage, manufacturing excellence, commitment to community, supporting our dealers and caring for customers.
