Abstract

Method and apparatus for a mainly temporary ventilation of a room. A fan (9) blows air from the room (1) through an inflatable balloon (15), being placed in a permanent opening, e.g. a window (5), in a wall (4) limiting the room. The balloon (15) is provided with at least one exhaust opening (16) being dimensioned so that an overpressure is built up inside the balloon sufficient to keep the balloon inflated and in abutment with the limitations (6) of the opening (5).
