Abstract: The invention relates to, but not exclusively to, a door or window including a sealing arrangement. The invention provides a door or window 1 movable between an open position and a closed position where the, wherein the door or window 1 comprises a first face 4 and a second face 5, and a resiliently deformable strip 6 located at least partially between the first face and second face. When the door or window 1 is in the closed position, the resiliently deformable strip 6 is movable between a sealing position, in which the resiliently deformable strip 6 is in sealing contact with a perimeter of the door or window opening, and an unsealed position, in which the resiliently deformable strip 6 is not in sealing contact with the said perimeter. The door or window further comprises at least one pressure bar 17 for moving the resiliently deformable strip 6 between the sealing position and the unsealed position.

Abstract: A frame (2) expandable in a structural opening has a stretchable substantially fluid impermeable cover membrane (25) disposed across the frame and arranged to stretch with expansion of the frame. The frame (2) is preferably expandable in mutually perpendicular directions, and provided with peripheral seals (27) for sealing in the structural arrangement. The barrier is conveniently fitted in openings such as doors and the like to provide a temporary barrier to rising floodwaters and the like.
