Description
Concealed sash hinged system compatible with any standard Channel 16 hardware. The sash is hidden behind the frame, reducing the visible aluminium section to 73.8 mm. This achieves a glazed surface of up to 85% of the window’s total glass, bringing more daylight indoors. Its avant-garde look can be completed with concealed drainage and concealed hinges.
