Abstract
A method for producing a triple insulating glazing unit is presented. According to the method, one pane is inserted into a groove of a spacer that is peripherally shaped to form a spacer frame to enframe the pane. A first pane and a second pane are connected to corresponding contact surfaces of the spacer frame by way of an upper edge and lateral edges of the first and second panes. Lower edges of the first and second panes are bent outward. Formed interpane spaces are filled from below with a protective gas, and the arrangement of the panes and the spacer frame is sealed and pressed together.

A method for producing a triple insulating glazing unit, the method comprising:
- a) inserting a pane into a groove of a spacer that is peripherally shaped to form a spacer frame, the spacer frame enframing the pane, wherein the spacer frame with the pane are arranged between a first pane and a second pane,
- b) connecting the first pane to a first pane contact surface of the spacer frame and connecting the second pane to a second pane contact surface of the spacer frame via a respective upper edge and respective lateral edges of the first pane and the second pane, and bending outward a respective lower edge of the first pane and of the second pane,
- c) filling, from below, interpane spaces with protective gas, and
- d) sealing and pressing together, a pane arrangement comprising the pane, the spacer frame, the first pane, and the second pane.
A triple insulating glazing unit comprising:
- a spacer that is peripherally shaped to form a spacer frame,
- a pane, enframed by the spacer frame, wherein the pane is inserted into a groove of the spacer,
- a first pane attached on a first pane contact surface of the spacer frame, and
- a second pane attached on a second pane contact surface of the spacer frame,
- wherein interpane spaces formed by the enframed pane, the first pane, and the second pane, are filled, from below, with a protective gas,
- wherein a pane arrangement comprising the enframed pane, the spacer frame, the first pane, and the second pane, is sealed and pressed together, and
- wherein an outer region of the pane arrangement between an outer surface of the spacer frame and outer edges of the first and second panes contains outer insulation filled peripherally and separated from the outer surface of the spacer via an insulating film applied to the outer surface.
