  • Vacuum IG window unit with edge seal at least partially diffused at temper and completed via microwave curing, and corresponding method of making the same
    Patent number: 6701749
    Abstract: A vacuum insulating glass (IG) unit and method of manufacturing the same. A peripheral or edge seal (11) of a vacuum IG unit is formed utilizing microwave energy (17) in order to enable tempered glass sheets (2, 3) 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 glass frit or solder glass. In certain embodiments, at least a portion (12, 12a, 301) of the edge seal material may be deposited on one or both substrates prior to a thermal tempering process so that during tempering the edge seal material is permitted to diffuse into (i.e., bond to) the glass substrate(s) (2, 3). Optionally, additional edge seal material (303) may be added after tempering. The final edge seal (11) is preferably formed via microwave heating (17) of the edge seal material.

  • Vacuum IG unit with alkali silicate edge seal and/or spacers
    Patent number: 6541083
    Abstract: A vacuum insulating glass (IG) unit. In certain embodiments, the peripheral or edge seal may include an alkali silicate, thereby enabling low cure temperatures to be used in forming the seal. This allows tempered glass substrates to retain a significant portion of their original temper strength, even after the seal is formed. In certain alternative embodiments, at least one spacer/pillar of the vacuum IG unit may be made of or include an alkali silicate.

  • Vacuum IG window unit with spacers between first and second edge seals
    Patent number: 6444281
    Abstract: A vacuum insulating (IG) unit and method of making the same. A low pressure space is provided between opposing substrates. An edge sealing system includes at least first and second edge seals. A plurality of spacers or pillars are located at least partially between the first and second edge seals, in order to better control the gap or spacing between the two opposing substrates.
