A 70 mm hinged hidden sash window system capable of uniting thermal features and profile slenderness. Thanks to its profile design, it maintains the sash totally hidden from the outside in such a way that it is impossible to distinguish between the fixed zones that the opening has and is achieved by minimizing the seen profile section up to 70 mm which then maximizes the window glazing surface.

This device comprising of two pieces located in the window ironmongery, allows a tiny opening (6 to 8 mm) that ensures a slow and gradual air entry whilst maintaining the window in the closed position. It can be applied to all types of openings: practicables, turn/tilts and sliders. The microventilation's mechanism for practicable and turn/tilt Windows can be regulated allowing variations in the ventilation flow.
