<p>The present invention provides a method and apparatus for assembling a small number of custom sealed double glazing units in which spacers can have different widths and panes of different assemblies can be differently sized. In accordance with one method of the invention, a spacer (31) having sealant (34) on opposing surfaces thereof is adhered to a first glass pane (21) and a resilient member (40) is positioned alongside a portion of the spacer. A seond glass pane (26) is positioned over the spacer so that it is partially adhered to the spacer to define an interpane space (36) around which the spacer is adhered, but with the resilient member preventing contact with the whole of the spacer, so maintaining a gap between a portion of the spacer and the second glass pane. The resulting assembly is moved into a gas exchange chamber (60), and air is removed from the chamber and accordingly also the interpane space. A gas having a coefficient of thermal conductivity lower than that of air is introduced into the chamber and accordingly also the interpane space, and the glass panes are pressed together while in the gas exchange chamber to compress the resilient member and adhere the second glass pane to all of the spacer to seal the interpane space.</p> |
