Abstract
A vacuum insulating glass (IG) unit and method of manufacturing the same. A peripheral or edge seal of a vacuum IG unit is formed utilizing microwave energy in order to enable tempered glass sheets of the IG unit to retain a significant portion of their original temper strength. In certain exemplary embodiments, the edge seal may be formed of solder glass.
Claims2
A thermally insulating glass unit comprising:
- first and second at least partially tempered glass substrates spaced apart from one another via at least a plurality of spacers;
- a microwave energy-formed hermetic peripheral or edge seal located at least partially between the first and second substrates, said peripheral or edge seal having been formed in a manner such that at least certain portions of the first and second substrates retain at least about 50% of their original temper strength after formation of the seal;
- and
- a space having a pressure less than atmospheric pressure provided between said substrates and sealed off by said microwave energy-formed hermetic peripheral or edge seal.
