Abstract

Disclosed is a glazing unit including an insulating glazing unit that is assembled with at least three panes for use in a window or as a part of a wall in a property, including a first pane that is located closer to the exterior of the property, a second pane located closer to the interior of the property, and a third pane located between the first and the second panes, whereby the first pane is provided on its surface that is facing inwards with a coating that reduces the radiation of heat in the form of an oxide layer burned into the surface of the pane, whereby also the second pane and the third pane are provided with a coating that reduces the radiation of heat in the form of an oxide layer that is burned into the surface of the pane.

Claims

1. A glazing unit comprising:

an insulating glazing unit that is assembled with at least three panes for use in a window or as a part of a wall in a property, the insulating glazing unit comprising

a first pane that is located closer to the exterior of the property,

a second pane located closer to the interior of the property, and

a third pane located between the first and the second panes,

wherein the first pane is provided on its surface that is facing inwards with a coating that reduces the radiation of heat in the form of a first oxide layer burned into the surface of the pane by sputtering, and

the second pane and the third pane are provided with a coating that reduces the radiation of heat in the form of a second oxide layer that is burned into the surface of the pane by sputtering.

2. The glazing unit according to claim 1, wherein the coating that reduces the radiation of heat of the second pane is arranged on the outwardly facing side of the second pane.

3. The glazing unit according to claim 1, wherein the coating of the third pane faces inwards toward the interior of the property.

4. The glazing unit according to claim 1, wherein the oxide layer is a metal oxide layer.

5. The glazing unit according to claim 1, wherein the oxide layer is of the same material on all panes in the glazing unit.

6. The glazing unit according to claim 1, wherein the outermost pane has an oxide layer of a material other than the material on the panes that are located inside of the outermost pane.

7. The glazing unit according to claim 1, wherein a fourth pane is arranged between the first and the second pane, the fourth pane being formed without an oxide layer.

8. The glazing unit according to claim 2, wherein the coating of the third pane faces inwards toward the interior of the property.

9. The glazing unit according to claim 2, wherein the oxide layer is a metal oxide layer.

10. The glazing unit according to claim 3, wherein the oxide layer is a metal oxide layer.

11. The glazing unit according to claim 2, wherein the oxide layer is of the same material on all of the panes in the glazing unit.

12. The glazing unit according to claim 3, wherein the oxide layer is of the same material on all of the panes in the glazing unit.

13. The glazing unit according to claim 4, wherein the oxide layer is of the same material on all of the panes in the glazing unit.

14. The glazing unit according to claim 2, wherein the outermost pane has an oxide layer of a material other than the material on the panes that are located inside of the outermost pane.

15. The glazing unit according to claim 3, wherein the outermost pane has an oxide layer of a material other than the material on the panes that are located inside of the outermost pane.

16. The glazing unit according to claim 4, wherein the outermost pane has an oxide layer of a material other than the material on the panes that are located inside of the outermost pane.

17. The glazing unit according to claim 2, wherein a fourth pane is arranged between the first and the second pane, which the fourth pane being formed without an oxide layer.

18. The glazing unit according to claim 3, wherein a fourth pane is arranged between the first and the second pane, the fourth pane being formed without an oxide layer.

19. The glazing unit according to claim 4, wherein a fourth pane is arranged between the first and the second pane, the fourth pane being formed without an oxide layer.

20. The glazing unit according to claim 6, wherein a fourth pane is arranged between the first and the second pane, the fourth pane being formed without an oxide layer.
