The inventon relates to a method of producing a plurality of multi-pane insulating glass assemblies in which the assemblies are formed into a self-supporting unit for further fabrication. Each assembly is provided with at least one exteriorly accessible opening, and the assemblies, supporting one another in surface-to-surface contact, are moved along a conveyor as a unit into a vacuum chamber. Vacuum is drawn on the unit to evacuate each interpane space, following which a gas having coefficient of thermal conductivity lower than that of air is introduced into the chamber to fill the interpane spaces of the glass assemblies. The assemblies as a unit are then conveyed out of the vacuum chamber and the exteriorly accessible openings are sealed. During the evacuation and refilling steps, the glass assemblies are maintained in a generally vertical orientation, and each glass assembly is supported by a neighboring assembly against undue bowing of the glass panes due to pressure differentials between the interior of the vacuum chamber and the interpane spaces.

Method for fabricating multi-pane insulating glass assemblies each having a sealed interpane space and each containing a gas having a coefficient of thermal conductivity lower than that of air, comprising: a. providing a plurality of glass assemblies, each comprising at least a pair of aligned, parallel, spaced glass panes having confronting surfaces defining therebetween an air-containing interpane space and having a spacer carried peripherally between the panes, each assembly having at least one exteriorly accessible peripheral opening extending through the thickness of a spacer located at the top of each assembly and through which gas may flow into and out of the interpane space, the panes of the plurality of glass assemblies extending in parallel, generally vertical planes and at least one pane of each assembly supporting a pane of a neighboring assembly; b. moving the plurality of glass assemblies as a unit into a chamber; c. evacuating the chamber to draw substantially all of the air from the interpane spaces; d. flowing into the evacuated chamber a gas having a coefficient of thermal conductivity lower than that of air, the gas refilling and occupying the interpane space; e. removing the glass assemblies as a unit from the chamber; and f. while maintaining the position of the assemblies as the same are removed from the chamber as a unit so that the at least one exteriorly accessible opening extends through the thickness of a spacer located at the top of each assembly, closing the at least one opening in each assembly to seal gas within the interpane space thereof.
