Abstract

An insulating glazing unit having a first pane, a second pane, a third pane arranged between the first pane and the second pane, an outer pane interspace, an inner pane interspace, and a spacer is described. The spacer having a plastic profile with a first glazing interior surface and a second glazing interior surface, a first pane contact surface, a second pane contact surface, a primary sealing means, and a main member containing a sealing material and a drying material. The plastic profile includes a groove, into which the third pane is inserted and which runs parallel to the first pane contact surface and to the second pane contact surface. The plastic profile separates the outer pane interspace from the inner pane interspace. The main member is arranged in the outer pane interspace between the plastic profile and the primary sealing means, the main member being adjacent the plastic profile and the primary sealing means.
