The motorized retractable window RW80e consists of a moveable pane and one or two fixed ones. At the touch of a button, the moveable pane is slid and stored behind the fixed pane. It is ideal for shop fronts. Its operation is quick and easy, it protects the enclosed space from heat or cold, wind and noise. Modified to fit the needs of any individual project, its design maximizes the glass surface without the need for a frame. The moving pane’s motion is achieved by employing an cylindrical electric motor which is placed in an aluminum box at the top of the device.
