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. 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 in the region of edges of said glass panes, said marginal join consisting of a spacer and also at least one adhesive, wherein the marginal join comprises a first adhesive at least in the region of two mutually opposite edges, said adhesive having a rigidity in the cured state of at least 50 N/mm², preferably of at least 100 N/mm².

2. Insulating glass according to claim 1, 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. Insulating glass according to claim 1, wherein the first adhesive is applied in the region of the at least two mutually opposite edges to a width of 20 mm to 200 mm, from the edge in the direction of the center of the glass panes.

4. Insulating glass according to claim 1, wherein the marginal join comprises the first adhesive in the region of those opposing edges in which the insulating glass is supported during the intended use thereof.

5. Insulating glass according to claim 1, wherein the marginal join comprises at least one second adhesive in the regions of the further edges of the glass panes, the second adhesive having a lower rigidity in the cured state than the first adhesive.

6. Insulating glass according to claim 1, wherein the at least one second adhesive is applied to a smaller width in the regions of the further edges than the first adhesive in the regions of the two opposing edges.

7. Insulating glass according to claim 1, wherein at least one respective anchoring element is inserted in the first adhesive in the regions of the at least two mutually opposite edges.

8. 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 at least one spacer.

9. Insulating glass according to claim 1, wherein the outermost glass panes of the at least two glass panes consist of a glass laminate.

10. Method for producing an insulating glass, in particular according to claim 1, said method comprising the following steps:

a) providing a first glass pane;

b) arranging at least one spacer circumferentially in the regions of the edges of the first glass pane at a distance from the edges;

c) applying a first adhesive, which has a rigidity in the cured state of at least 50 N/mm², between at least two mutually opposite edges of the first glass pane and the spacer,

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

11. Insulating glass according to claim 1, wherein the first adhesive is applied in the region 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.
