On both sides of the building opening, this seal has apron-like sealing strips which are designed as air-filled inflated bodies and over which there is located a roof-type, panel-type covering, in front of which there is a transversely running apron which is likewise designed as an inflated body. In order to eliminate heat losses in the case of heated buildings or cold losses in the case of cold stores or the like, the covering is designed as a sandwich panel having, between thin-walled outer layers, an insulating, porous or cellular layer which is a wall thickness which is considerably greater than that of the two outer layers.
