ABSTRACT:
There is described a multiple-pane glazing unit which has top and bottom edges and two side edges and two or more, parallel glazing sheets enclosing a vertical cavity, or cavities. A convective-flow barrier is positioned adjacent to the bottom edge of the glazing sheets within the cavity, or cavities. The barrier is a strip-like member, dimensioned to be in sealing contact, in cold temperature conditions, with both glazing sheets which form a cavity between them. The strip is of a selected material, or of a physical configuration, such that it is flexible of itself or has a flexible edge or edges to accommodate variations in cavity width caused by, say, temperature changes along the length of the barrier. A second similar convective-flow barrier may be positioned adjacent and parallel to the top edge of the unit within the cavity and indeed, intermediate barriers may also be provided between top and bottom barriers and parallel thereto. A vertically extending barrier or barriers intersecting the convective-flow barriers may also be provided.
