A method for manufacturing vacuum insulating glazings, wherein said method comprises the steps of: providing a plurality of first pane elements, applying a soldering material in paste form on a first surface of each first pane elements, along side edges of the first pane elements, where the soldering material is configured for subsequent connection with a second pane element in order to provide a sealing between the outside of the vacuum insulating glazings and an inside void of the vacuum insulating glazings where vacuum is to be provided, moving the first pane elements comprising the soldering material into a thermal treatment compartment (11, 14), and providing a thermal treatment (40, 50) of the soldering material on the first pane elements, so as to dry out a solvent material from the soldering material, moving the first pane elements from the thermal treatment compartment (11, 14), and subsequently connecting the first pane elements to second pane elements by means of the dried out soldering material, wherein at least in a step (S1, S2) of said thermal treatment, a gas convection treatment process is provided, wherein the gas convection treatment process comprises that the heat exchange between the first pane elements and the thermal treatment compartment (11, 14) is provided by means of a forced convection of a temperature controlled gas, which is supplied to said first surface and/or a second surface of the first pane elements opposite to said first surface of each of the first pane elements by means of a plurality of nozzles (12, 13) of the thermal treatment compartment (11, 14) directed towards said first and/or second surfaces (3, 4), and wherein the gas (40, 50) supplied during the gas convection treatment process, is filtered air which is filtered by a filtering unit before it is supplied towards the first pane elements. providing a plurality of first pane elements, applying a soldering material in paste form on a first surface of each first pane elements, along side edges of the first pane elements, where the soldering material is configured for subsequent connection with a second pane element in order to provide a sealing between the outside of the vacuum insulating glazings and an inside void of the vacuum insulating glazings where vacuum is to be provided, moving the first pane elements comprising the soldering material into a thermal treatment compartment (11, 14), and providing a thermal treatment (40, 50) of the soldering material on the first pane elements, so as to dry out a solvent material from the soldering material, moving the first pane elements from the thermal treatment compartment (11, 14), and subsequently connecting the first pane elements to second pane elements by means of the dried out soldering material, wherein at least in a step (S1, S2) of said thermal treatment, a gas convection treatment process is provided, wherein the gas convection treatment process comprises that the heat exchange between the first pane elements and the thermal treatment compartment (11, 14) is provided by means of a forced convection of a temperature controlled gas, which is supplied to said first surface and/or a second surface of the first pane elements opposite to said first surface of each of the first pane elements by means of a plurality of nozzles (12, 13) of the thermal treatment compartment (11, 14) directed towards said first and/or second surfaces (3, 4), and wherein the gas (40, 50) supplied during the gas convection treatment process, is filtered air which is filtered by a filtering unit before it is supplied towards the first pane elements.
