The Schüco ADS 50.NI uninsulated aluminum system has been specially designed for interiors. Despite the narrow width and the very small basic depth of 50 mm, a stable type of construction allows even for units with a room height. The system is also fully compatible with the uninsulated Schüco aluminum window system. The universal use of the Schüco Door ADS 50.NI is proof of the mature system technology of this highly advanced series of aluminum doors.
