Sky-Frame Drive’s electric drive facilitates simple and virtually noiseless operation of up to 6 (3+3) sliding panels at the press of a button. The drive is concealed in the ceiling section and allows the window panels to move automatically. The new Sky-Frame Touch control button is a convenient way to open and close sliding windows using the SI-1000 electric drive. Entire systems can be elegantly opened, closed or stopped at any point right at the window by applying gentle pressure on the rocker switch, which is unobtrusively integrated into the locking handle.
