12. A method for producing an insulating glazing unit, comprising:
-
a) fixing a spacer on a first pane and a second pane by way of a primary sealant on each pane contact surface of the spacer thus forming an intermediate arrangement, the intermediate arrangement further comprising a glazing interior bordered by inner faces of the first pane and of the second pane and a glazing interior surface of the spacer, and an external interpane space adjacent the first pane, the second pane, and the external surface, b) pressing the intermediate arrangement, c) filling a secondary sealant into the external interpane space, and d) filling a tertiary sealant into the external interpane space, wherein the penetration index of the primary sealant is between 45 and 100 and the penetration index of the secondary sealant is between 20 and 40, with the penetration index being referred to ISO 2137-DIN 5180 and measured at a temperature of 60°
