Abstract

An insulating glazed element including at least two glass sheets, separated from each other by a space and joined at their periphery by a seal, and at least one section. The glazed element has at least one heating border on at least one face of at least one glass sheet, and the border is covered by the section and joined to the section by a heat-conducting seal.

Claims

1. An insulating glazed element comprising:

at least two glass sheets, separated from each other by a space and joined at a periphery thereof by a seal, and at least one frame section,

wherein said element has at least one heating border on at least one face of at least one of the glass sheets, said heating border being connected at opposite ends thereof to an electrical supply terminal for being heated, and

wherein said border is covered by the at least one frame section and is joined to the at least one frame section by a heat-conducting seal.

2. The element as claimed in claim 1, wherein the heating border includes an enamel or a resin containing metal particles.

3. The element as claimed in claim 2, wherein the metal particles are chosen from particles of silver, nickel, zinc, copper, graphite, or precious metals such as gold, platinum or palladium.

4. The element as claimed in claim 1, wherein the heating border is borne by an external face of an outer glass sheet of the glass sheets and enclose an end portion of said at least one of said glass sheets.

5. The element as claimed in claims 1, wherein the border is borne by an internal face of an outer glass sheet of the glass sheets.

6. The element as claimed in claim 1, wherein the border is borne by an external face of an intermediate or inner of the glass sheets.

7. The element as claimed in claim 1, wherein the at least two glass sheets comprises at least three glass sheets and said heat conducting element contacts an intermediate glass sheet of said at least three glass sheets.

8. The element as claimed in claim 1, wherein an outer sheet of the glass sheets comprises a glass sheet having undergone thermal toughening.

9. A refrigerated enclosure comprising at least one glazed element according to claim 1.

10. An insulating glazed element comprising:

at least two glass sheets, separated from each other by a space and joined at a periphery thereof by a seal, and at least one-frame-section,

wherein said element has at least one heating border on at least one face of at least one of the glass sheets, and

wherein said border is covered by the at least one-frame-section and is joined to the at least one-frame-section by a heat-conducting seal; and

an intermediate heat-conducting element combined with the heating border, configured to increase a contact area between the border and the heat-conducting seal.
