The invention concerns a window or French window having concealed operating sash(es) comprising an outer glazing (7) and an inner glazing (9). The zone (Z) between said glazing panels communicates with the window outside part through a passage in the window case (1) and orifices (13) in the operating sash (4). A sealing pipe or duct can be interposed in the space between the case and the opening sash at the communicating orifices, which pipe consists for example of plastic parts (16, 17) whereof one is integral with the case and the other with the operating sash with sealing contact between the two. Preferably, the space between the outer glazing (7) and the inner glazing (9) is sufficient for housing a masking device such as a blind with blades or the like. Moreover, the opening sash (4) can consist of two modules assembled in the zone between the glazing panels: an inner module (140) bearing the inner glazing (9) and an outer module (141) bearing the outer glazing (7); the outer module is provided with communicating orifices and is fixed on said inner module, supported on the window case (1) fixed frame (5).
