Sealing unit with low heat transfer between an inner and an outer space (9, 11) for sealing an opening (13) in a wall (15) comprises an inner pane (3) and an outer pane (5) arranged a distance apart. The inner pane is joined in an air-tight manner to the outer pane in the region of the pane edges (17, 19) by a connecting element (20). The internal gas pressure between the inner and outer panes is lower than the ambient pressure outside the inner and outer panes. The connecting element connects the inner pane to the outer pane not in a rigid manner but so that they can move relative to each other, especially flex, to compensate for e.g. thermal dilatation differences between the inner and outer panes. An independent claim is also included for an evacuating device for the above sealing unit. |
