Integrity Windows & Doors

Warren Window & Supply Integrity Windows and Doors

Integrity Windows and Doors from Marvin are made with Ultrex¬ģ pultruded fiberglass, a material patented over 20 years ago when Integrity pioneered fiberglass windows and doors.

They outperform roll-form aluminum, vinyl, and vinyl/wood composites in virtually every measurable category. Ultrex is durable, strong, stable, low-maintenance and efficient. While other windows and doors might bend, break, or crack over time, Integrity products hold strong and perform under great stress without showing age or wear.  Available in Wood-Ultrex, the best of both worlds, with the warmth and beauty of wood on the interior and the durability of Ultrex on the exterior, and All Ultrex built with Ultrex throughout.
