Integrity Windows and Doors from Marvin

Integrity Windows and Doors are made with Ultrex®, a pultruded fiberglass that Marvin has patented that outperforms and outlasts vinyl, roll-form aluminum and other fiberglass composites. Integrity uses Ultrex and their proprietary pultrusion process to manufacture high-demand windows and doors that endure all elements without showing age or wear.

Built to Perform for New England
Integrity Windows and Doors are a perfect match for the harsh New England climate and 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.

Excellence In Efficiency
Integrity Windows and Doors are more than just tough, they’re also energy efficient. Integrity products meet or exceed federal ENERGY STAR® guidelines. So with Integrity windows and doors, not only will you reduce your environmental impact, but you’ll also see significant savings on your heating and cooling bill over time.
