Abstract
The window (1) comprises a frame (2) having a top member (3), a bottom member (4) and two side members (6), and a sash (7) having a top member (8), a bottom member (9) and two side members (10, 11). A screening arrangement (12) is provided in order to cover the ventilating aperture at least partly in the ventilating position. To achieve a discreet screening arrangement having minimum influence on the functioning of the window, the screening arrangement (12) includes at least one screening element (13, 23, 33), which, in a closed position of the window (1), is arranged in a storage position at the interface between frame (2) and sash (7), and in the ventilating position extends between the frame bottom member (4) and the sash bottom member (9), and/or between the frame top member (3) and the sash top member (8). Each of the screening elements (13, 23, 33) is connected with the sash or frame top or bottom member (8, 3, 9, 4) and is in releasable engagement with the corresponding frame (3, 4) or sash member (8, 9) within the limited angle range.
