Integrity Wood-Ultrex Insert Double Hung Window

Combining pultruded fiberglass, wood interiors and flexible fitting, Integrity's Wood-Ultrex is a frame-in-frame design built in 1/64-inch increments for appropriate sizing up to 4.5-feet by 7-feet. Upper and lower sashes can be opened for cleaning and a window control opening device can be used to prevent falls. The Wood-Ultrex comes in operating, picture and transom units, and provides a 3.25-inch replacement frame with through-jamb installation.
