The window (1) is provided with a frame (2) and a sash (3) connected to the frame (2) by means of at least one hinge connection providing a hinge axis substantially parallel with top and bottom members of the sash, so that through an opening movement of the window (1), the sash (3) is adapted to be moved between a closed position, an intermediate ventilating position and an open position, in which ventilating position the sash plane forms an angle within a limited angle range with the frame plane to provide at least one ventilating aperture (20) in the circumferential of the frame (2) and/or sash (3). A screening arrangement is provided to cover at least one ventilating aperture (20) in the ventilating position. The screening arrangement comprises at least one screening element (21) incorporated in a member of the frame (2) and/or sash (3) and arranged so as to form a ventilating passage (22). The screening element (21) automatically spans the ventilating aperture (20) between the sash (3) and frame plane (2) in the ventilating position, while being incon-spicuous in both the open and the ventilating position of the window (1). |
