Abstract: A structural assembly comprises a frame structure and infill panes or panels retained in the frame structure with weathertight seals at their peripheral edges and at marginal portions of their inner faces adjacent to said edges. Clamping means engaging the outer faces of the panes or panels apply sealing pressure for said marginal portions but are not relied on to provide seals. In a preferred construction the sealing means are substantially flush with the outer faces of the panes or panels and the clamping means comprise a series of small and widely spaced devices that bridge contiguous panes or panels.

Abstract: A structural assembly comprises a cellular frame structure in the cells of which panes or panels are mounted to form a curtain wall. The frame structure carries external sealing gaskets for the peripheries of said panes and arranged so that said panes are put in place from the interior face of the structure. Internally of said panes, clamping means are disposed to urge said panes into sealing engagement with the gaskets with an adjustable force. The external sealing gaskets cover those parts of the frame structure that project externally of said panes.

Abstract: A planar structural assembly has a series of cells formed by elongate structural members, the cells each receiving a pane or panel. To provide a weather-seal, closed loops of resilient sealing strips extend around the exterior edge of each pane or panel and are mounted on auxiliary members secured to the structural members. The auxiliary members clamp the sealing strips in compression against their panes or panels to ensure the seal there. The contiguous edges of the sealing strips of adjacent cells are locked in place and a seal formed between them by locking or zipper strips.
