INTEGRITY Windows are Built to Perform

From window engineering and a vast array of sizes and shapes, to the folks in customer service, Integrity Windows are built to perform!

The Ultrex Advantage

Strong, stable, durable and virtually indestructible, Ultrex is possibly the perfect building material, creating windows that leave other materials in the dust. If you've ever encountered a dented or corroded roll-form aluminum window or a faded, cracked vinyl window, the advantages of Ultrex are obvious..

Wood-Ultrex Windows

Wood-Ultrex Series windows feature exteriors of Ultrex fiberglass and beautiful real wood interiors. Setting new standards in low maintenance and top aesthetics, Integrity Wood-Ultrex series combines the most popular sizes and styles of windows and improves them with Ultrex® durability, elegant wood interiors and standard ENERGYSTAR-qualified performance. Take a look at our full line of products, then explore the range of options that make an Integrity window the perfect fit for you.

All Ultrex Windows

All Ultrex Series windows feature Ultrex construction inside and out. Beautiful, easy to use and as low-maintenance as a material can get, Ultrex® provides exceptional aesthetics, outstanding durability, and standard ENERGY STAR-qualified performance. Six exterior finishes combine with pultruded fiberglass construction to offer virtually indestructible exteriors, while the low-maintenance classic white profiled interiors provide a beautiful classic appearance.

IMPACT Products

Finally a coastal product designed to withstand life on the coast. Integrity IMPACT products are Impact/Wind Zone 3 rated for winds up to 140 mph and are constructed of Ultrex®, a revolutionary pultruded fiberglass material. Ultrex resists corrosion and UV degradation while withstanding heat up to 350°; so it is perfectly suited to resist the salt, heat, sun, wind and humidity that accompany coastal living. IZ3 rated performance designed to perform every day.
