The ventilation window has inner and outer closeable ventilation slots (7, 10, 39) in upper and lower, horizontal fixed frame parts (2, 3) which are symmetrical to each other. Ventilation slots (7, 10, 39) can be closed by means of identical, outer and inner pivot-type profile parts (21, 22) which are arranged in the frame parts (2, 3) and can be actuated together in the opening direction or closing direction by means of a handle arranged on the inner pivot-type profile part (23). <IMAGE>
