Method for gas-filling of sealed glazing units with a number of panes (2, 3, 4), sealed hermetically with respect to each other, with intermediate spaces (5, 6). In this method at least one opening (9) is allocated to each space (5, 6) for introduction of gas in the liquid state, and at least one opening (10) for discharge of the air which is situated in the spaces after the panes have been joined together. The gas, which is in the gaseous state at the use temperature of the sealed glazing unit (1) and at atmospheric pressure, is converted to the liquid state by compression and/or cooling. In its liquid state the gas is introduced into the respective space (5, 6) through the first opening (9). Heat, which is required for volatilization of the liquid gas, is supplied. During the volatilization process the second opening is kept open for emission of the expelled air. |
