Claims
- 1. A vacuum glazing comprising two sheets of glass hermetically sealed around the edge by a solder glass edge seal with a thermally insulating internal vacuum, and an array of support pillars placed between the glass sheets, wherein one of the sheets of glass is laminated to a further sheet of glass.
- 2. A method of manufacturing a vacuum glazing, the vacuum glazing comprising two sheets of glass hermetically sealed around the edge with a thermally insulating internal vacuum, and an array of support pillars placed between the glass sheets, the method comprising the steps of:
- holding the glass sheets at a high temperature while a solder glass edge seal is formed; and
- subsequently laminating at least one of the glass sheets with a further sheet of glass.
- 3. A method according to claim 2, wherein the procedure consists of:
- placing a layer of plastic material on one surface of the glazing, and then locating the further glass sheet above this material;
- forcing the entire assembly together; and then
- heating the assembly to a temperature at which the plastic material softens and bonds to both sheets.
- 4. A method according to claim 3, wherein the laminating process is performed on both sides of the vacuum glazing.
