The SL80/81 Folding Series from NanaWall Systems is a thin glass folding wall. The frame profiles are 17/8 inches but can be up to 10 feet tall and 3 feet wide. The glass wall can open both inward and outward, features an aluminum frame, and rolls on stainless steel wheels on a stainless steel track. The SL80 has a smooth frame profile, while the SL81 is more angular. Even though they are thin, the walls are triple-insulated and meet Energy Star standards.
