Abstract

A shutter comprises a plurality of flaps 2 rotatable about their respective longitudinal axes. In order to provide efficient and reliable sealing of the longitudinal edges of the flaps 2 in their closed position, whilst avoiding the need for using any substantial force to bring the flaps to that position, one edge of each flap carries a sealing strip by an anchorage part 8 thereof, the sealing strip also having a sealing lip 9 which is connected only along one edge to the anchorage part 8 and provides the necessary contact surface for engagement by the confronting edge of the next adjacent flap 2. The flaps 2 are formed of sheet metal strips 5, 6 and the sealing strip is made of rubber. Adjacent flaps 2 may be rotatable in the same or opposite directions. <IMAGE>
