Abstract: A method of producing multi-pane glass units having a non-air gas in the interpane space. The method includes the steps of assembling several glass units, each of which has a pair of spaced glass panes and a peripheral spacer. A separator device is interposed between one of the panes and the peripheral spacer of each of the units. When the units have been so assembled, a vacuum is drawn on the units in an evacuable chamber to remove substantially all of the air from the interpane spaces. The chamber is then refilled with a suitable gas, such as argon, to refill the interpane space of each of the units. The separator is then removed from the glass units, to close the opening between the pane and the peripheral spacer of each unit, thereby completely sealing the interpane space of each unit from the vacuum chamber environment. The units can then be removed from the vacuum chamber and further processed.
