Abstract

An insulating glazing unit having a first pane, a second pane, an outer pane interspace, an inner pane interspace, and a spacer is described. The spacer has a glazing interior surface, a first pane contact surface, and a second pane contact surface, a plastic profile, a primary sealing means, and a main member. The main member contains a sealing material containing a drying material. The plastic profile separates the outer pane interspace from the inner pane interspace. The main member is arranged in the outer pane interspace adjacent the plastic profile and the primary sealing means is arranged in the outer pane interspace adjacent the main member.

the primary sealing means is arranged in the outer pane interspace adjacent the main member.

17. The insulating glazing unit according to claim 16, further comprising a third pane arranged between the first pane and the second pane,

wherein:

the glazing interior surface comprises a first glazing interior surface and a second glazing interior surface,

the plastic profile comprises;

a first plastic profile on the first glazing interior surface between the first pane and the third pane; and

a second plastic profile on the second glazing interior surface between the third pane and the second pane,

the main member is arranged between the first pane and the second pane, and

the third pane protrudes into the main member in a region between the first plastic profile and the second plastic profile.

18. The insulating glazing unit according to claim 16, wherein:

the first pane contact surface and the second pane contact surface surround the plastic profile and the primary sealing means, and

the primary sealing means encloses the main member on three sides.

19. The insulating glazing unit according to claim 16, wherein the plastic profile comprises at least one opening to enable gas and moisture exchange between the main member and the inner pane interspace.

20. The insulating glazing unit according to claim 19, wherein the at least one opening comprises a plurality of openings.

21. The insulating glazing unit according to claim 16, wherein:

in the outer pane interspace between the first pane and the second pane, a secondary sealing means is arranged adjoining the primary sealing means, the secondary sealing means comprising a polymer or silane-modified polymer.

22. The insulating glazing unit according to claim 21, wherein the secondary sealing means comprises one or more of organic polysulfides, silicones, room-temperature vulcanizing silicone rubber, high-temperature vulcanizing silicone rubber, peroxide vulcanizing silicone rubber, and/or addition vulcanizing silicone rubber, polyurethanes, or butyl rubber.

23. The insulating glazing unit according to claim 17, wherein the third pane protrudes into the main member through a partial height of the main member relative to an entire height of the main member.

24. The insulating glazing unit according to claim 23, wherein the partial height is in a range of 20% to 80% of the entire height.

25. The insulating glazing unit according to claim 23, wherein the partial height is in a range of 30% to 60% of the entire height.

26. The insulating glazing unit according to claim 17, wherein the third pane protrudes beyond an entire height of the main member into the main member and/or the third pane protrudes through the primary sealing means.

27. The insulating glazing unit according to claim 26, wherein the third pane protrudes through the primary sealing means.

28. The insulating glazing unit according to claim 26, wherein the third pane protrudes through the secondary sealing means.

29. The insulating glazing unit according to claim 16, wherein the main member contains a sealing material and a desiccant.

30. The insulating glazing unit according to claim 29, wherein the sealing material comprises a hot-melt adhesive, polyisobutylene, and/or butyl rubber.

34. A method for producing the insulating glazing unit according to claim 16, the method comprising:

preparing a spacer by coextruding a main member containing a sealing material containing a desiccant and a primary sealing means on a plastic profile,

mounting a first pane on a first pane contact surface of the spacer and mounting a second pane on a second pane contact surface such that the plastic profile is arranged on a glazing interior surface of the spacer, and

pressing together a pane arrangement composed of the panes and the spacer, thereby producing a stable adhesive bond of the pane arrangement.

35. A method for producing an insulating glazing unit according to claim 17, the method comprising:

arranging a first plastic profile between a first pane and a third pane and arranging a second plastic profile, at a same height as the first plastic profile, between the third pane and a second pane, the first plastic profile and the second plastic profile forming a plastic profile at an outer pane interspace of the insulating glazing unit, and

coextruding onto the plastic profile a primary sealing means and a main member containing a sealing material with desiccant.

36. A method for producing an insulating glazing unit according to claim 17, the method comprising:
