COR 70 Hidden Sash C16 ST

Hidden sash hinged system compatible with any standard channel 16 hardware. Its attractive design conceals the sash behind the frame, reducing the visible aluminium section to 73.8 mm. This makes it possible to achieve a glazed surface of up to 85% of the total window area, helping more light enter the interior. Its avant-garde appearance is complemented by the option of hidden drainage and concealed hinges.
