Abstract

The present application relates to an insulating glass (1) having at least two glass panes (2, 3) spaced apart from one another. The insulating glass (1) comprises at least one marginal join arranged between the glass panes (2, 3) in the region (8, 9, 10, 11) of edges (4, 5, 6, 7) of said glass panes (2, 3), said marginal join consisting of a spacer (12) and also at least one adhesive. The marginal join comprises a first adhesive at least in the region (8, 9) of two mutually opposite edges (4, 5), said adhesive having a rigidity in the cured state of at least 50 N/mm², preferably of at least 100 N/mm².

Claims

1. An insulating glass having at least two glass panes spaced apart from one another, said insulating glass comprising at least one marginal join arranged between the glass panes, said marginal join comprising a spacer and also at least one first adhesive and at least one second adhesive, the marginal join comprising the spacer and only the first adhesive in a first region between a first edge of said insulating glass and the spacer and in a second region between a second edge of said insulating glass and said spacer, said second edge lying opposite of said first edge on said insulating glass, said first adhesive having a rigidity in a cured state of at least 50 N/mm², wherein the marginal join comprises the spacer and only the second adhesive in a third region between a third edge of said insulating glass and said spacer and in a fourth region between a fourth edge of said insulating glass and said spacer, said third edge and said fourth edge lying opposite to each other on said insulating glass, wherein the second adhesive has a lower rigidity in the cured state than the first adhesive.

2. The insulating glass according to claim 1, wherein the adhesive has a short-term stability with respect to erosion by wind loads of at least 5 N/mm², preferably of at least 10 N/mm².

3. The insulating glass according to claim 1, wherein the first adhesive is applied in the first region and the second region to a width of 20 mm to 200 mm from said first and said second edges in a direction of the center of a glass panes.

4. The insulating glass according to claim 1, wherein the marginal join comprises the first adhesive in the regions of the first and second edges in which the insulating glass is supported during an intended use of the insulating glass.

5. The insulating glass according to claim 1, wherein the at least one second adhesive is applied to a smaller width in the third and fourth regions than the first adhesive in the first and second regions.

6. The insulating glass according to claim 1, wherein at least one anchoring element is inserted in the first adhesive in the first or second regions.

7. The insulating glass according to claim 1, wherein a film consisting of a polymer is stretched between the at least two glass panes and parallel thereto, wherein the film is spaced apart from each of the glass panes by way of the at least one spacer.

8. The insulating glass according to claim 1, wherein outermost glass panes of the at least two glass panes consists of a glass laminate.

9. The insulating glass according to claim 1, wherein the first adhesive is applied in the first area of the least two mutually opposite edges to a width of 80 mm to 120 mm from the edge in the direction of the center of the glass panes.

10. The insulating glass according to claim 1, wherein the first adhesive has a rigidity in the cured state of at least 100 N/mm².

11. A method for producing the insulating glass according to claim 1, said method comprising the following steps:

a) providing a first glass pane of said two glass panes;

b) arranging the at least one spacer circumferentially in the first, second, third and fourth region of the first, second, third and fourth edge, respectively, of the first glass pane at a distance from said edges;

c) applying only the first adhesive, which has a rigidity in a cured state of at least 50 N/mm², in said first and said second regions,

d) applying only the second adhesive, which has a lower rigidity in the cured state than the first adhesive, in said third and said fourth regions,

wherein the second glass pane is positioned on the at least one spacer before or after the application of the first adhesive.
