Beautiful Designs. Amazing Performance.
From Classic to Contemporary designs, Infinity from Marvin patio doors will fill your home with bigger views and more daylight. Our patio doors are made from Ultrex® fiberglass, which will not melt or lose its true shape in the Arizona sun. Ultrex can withstand exposure to temperatures as high as 285 F!
Ultrex fiberglass is an ultimate performer. It’s beautiful. It’s 8X stronger than vinyl, expands 87% less than vinyl, and expands 75% less than Fibrex.
