The Schüco sunshade CCB (Concealed Composite Blind) has been specially developed for use in the composite window Schüco AWS 120 CC.SI. The system is installed in the leaf between exterior single glazing and interior insulating glazing, the head profile of the blind is completely covered. With this a minimal stack height is achieved with up retracted blind, preventing lateral slit light when the blinds are downed. The special alloy 25 mm wide aluminum slats can be moved up and down and turned by a 24-volt electric motor.
