Integrity Windows and Doors by Marvin

Marvin Integrity windows and doors are Built to Perform®. More than 20 years ago, Marvin pioneered the development of long-lasting, low-maintenance windows made with Ultrex pultruded fiberglass. Today, Marvin products are some of the industry’s most sought-after solutions for commercial and residential projects.

Benefits of Ultrex fiberglass

All Marvin Integrity windows and doors are made with Ultrex, Marvin’s revolutionary patented pultruded fiberglass that offers unparalleled durability, even when exposed to the toughest outdoor elements.

Built for extremes

No matter what Mother Nature has in store, Ultrex can handle it. Ultrex is 4x stronger than composite and 8x more rigid than vinyl. It does not corrode and is durable enough to withstand severe weather conditions and is ideal for buildings in hurricane zones.

Energy efficient

Ultrex windows are made with a Low E coating that minimizes the amount of infrared and ultraviolet light that can pass through the window. This coating can help lower your bills by dramatically reducing heat loss in cold weather and cooling costs in the warmer weather.

Ultrex also expands and contracts like glass, ensuring that Integrity windows seal tight and resist air leakage and water penetration.

Retains color, resists cracks

Heat and UV light have met their match. Ultrex features an outstanding acrylic finish that retains color — even very dark shades. It resists fading, UV degradation, cracking, denting, chipping and peeling, and is the only fiberglass finish to be third-party verified to the American Architectural Manufacturers Association’s (AAMA) 624-10 finish specifications.
