Built to Perform®
Virtually maintenance-free Ultrex® Fiberglass exterior, real wood interior.
Unmatched Durability and Longevity
Outperforms and Outlasts vinyl and roll-form aluminum
Integrity windows are made with Ultrex pultruded fiberglass, a material developed 20 years ago that is eight times stronger than vinyl and three times stronger than wood/vinyl composites. Integrity has led the category ever since with a commitment to a product that is tough, long lasting, and worry-free.
Ultrex is quite possibly the perfect building material for windows. It’s durable, strong, low-maintenance and energy efficient. Stronger than strong, Integrity windows outperform roll-form aluminum, vinyl, and vinyl/wood composites in virtually every measurable category. While other windows might bow or chalk over time, Integrity windows undergo a patented, high-performance coating process, resulting in windows that perform under great stress without showing age or wear.
Integrity products are manufactured by Marvin, a company with a rich history of craftsmanship, knowledge and dedication dating back to 1912.
