Integrity from Marvin Windows and Doors

Integrity windows and doors are made with Ultrex pultruded fiberglass, a material patented nearly 20 years ago when Integrity pioneered the fiberglass windows and door category. Integrity has led the category ever since with a commitment to a product that is tough, smart, long lasting, and worry-free.
The facts prove it. Ultrex is quite possibly the perfect building material for windows and doors. It's durable, strong, stable, low-maintenance and efficient. Integrity windows and doors made with Ultrex pultruded fiberglass outperform roll-form aluminum, vinyl, and vinyl/wood composites in virtually every measurable category. While other windows might bend, break, or crack over time, Integrity windows hold strong and perform under great stress without showing age or wear.
