The present means therefor comprise a continuous resilient strip (3) incorporating a channel (12) by which it is fitted about the periphery of the additional pane (6) to have a section (11) standing proud of a face (6<a>) thereof. The additional pane (6) is marginally undersized relative to the existing pane (7) whereby, together with the seal (3) mounted thereon, pane (6) can be positioned in face to face juxtaposition to pane (7) with strip (3) interposed therebetween. By way of either a non-return valve (17) in pane (6) or an hypodermic type insertion either through seal (3) or between seal (3) and pane (7), the cavity (13) between the panes (6, 7) is partially evacuated. The resultant suction sealling impinges the panes (6) and (7) to seal (3) and thus together to provide a double glazed installation. The same method, means can be used in production of double glazed units. |
