Strong. Beautiful. Efficient. Innovative. Easy. Durable. Amazingly, Integrity windows and doors can claim them all, by combining incredibly durable, innovative materials with the beauty of traditional craftsmanship. Effortless operation with minimal service is what’s achieved . It's not just the best of its class. It's the only one of its class. Ultrex® is simply the most durable and energy efficient material available, with the least conductivity and response to heat or cold for a weathertight window. That's why it's used in bridges, spacecraft--and now, windows and doors. The best of high tech materials is matched by the ultimate in hand-crafted beauty. Traditional wood interiors, exceptional materials and the beautiful lines you've come to expect from Marvin Windows and Doors. Now from Integrity.
