Zola sliding doors are custom-made and can be shipped fully assembled in sizes up to 20 feet wide and 8 feet high; larger sizes—up to just under 40 feet by 11 feet (WxH)—are delivered as a knock-down kit.

The “Thermo Clad” model installed on this project was 108 3/4 by 111 inches (2,819 mm x 2,762 mm, WxH), but was delivered knocked-down so it would fit through the existing doorways.
