Abstract

Disclosed is an insulating glazing which includes two glass sheets spatially separated by an interposed air layer and assembled by a set of two plastic seals, the inside seal being extruded in the form of a bead and the peripheral seal filling all or part of the groove delimited by the glass sheets and the bead which includes on its face in contact with the peripheral seal a protuberance and/or a groove for mutual anchoring of the two seals.

Claims

1. Insulating glazing, which comprises:

two glass sheets spatially separated by an interposed air layer;

a seal which consists of two overlapping plastic seals each adhering to said two glass sheets, respectively, and which include an inside seal in the form of a bead and a peripheral seal for filling at least part of a space defined by said two glass sheets, wherein said inside seal comprises, on a face thereof in contact with said peripheral seal, a protuberance extending toward an inside face of one of said glass sheets and a groove for mutual anchoring of said inside seal and said peripheral seal.

2. Insulating glazing according to claim 1, wherein said inside seal comprises butyl rubber containing a dessicant and said peripheral seal comprises polysulfide.

3. Insulating glazing according to claim 2, wherein said two glass sheets each have a thickness of between 2 and 3 mm and wherein an interposed air sheet has a thickness of between 2 and 5 mm.

4. Insulating glazing according to claim 1, wherein said two glass sheets each having a thickness of between 2 and 3 mm and wherein said interposed air sheet has a thickness of between 2 and 5 mm.

5. Insulating glazing according to claim 1, wherein said two glass sheets each comprise bent glass sheets.

6. Insulating glazing, which comprises:

two glass sheets spatially separated by an interposed air layer;

a seal which consists of a set of two overlapping plastic seals which include an inside seal in the form of a bead and a peripheral seal for filling at least part of a space defined by said two glass sheets, wherein said inside seal comprises, on a face thereof in contact with said peripheral seal, a groove extending toward an inside face of one of said glass sheets for mutually anchoring said inside seal and said peripheral seal.

7. Insulating glazing, which comprises:

two glass sheets spatially separated by an interposed air layer;

a seal which consists of a set of two overlapping plastic seals which include an inside seal in the form of a bead and a peripheral seal for filling at least part of a space defined by said two glass sheets, wherein said inside seal comprises, on a face thereof in contact with said peripheral seal, a protuberance extending toward an inside face of one of said glass sheets for mutually anchoring said inside seal and said peripheral seal.
