Panasonic Develops Tempered Vacuum Insulated Glass to Increase Variations in Vacuum Insulated Glass with Its Proprietary Technology | Headquarters News | Panasonic Newsroom Global
Osaka, Japan –
Panasonic Corporation today announced that it has developed tempered vacuum insulated glass and another vacuum insulated glass with transparent pillars that it has successfully put into practical use for the first time in the industry(*1).
In 2017, Panasonic entered the vacuum insulated glass business by applying its plasma display panel development and manufacturing technology.
Since then, Panasonic has been manufacturing vacuum insulated glass having the industry’s top-class(*2) heat insulation performance for glass with a total thickness of 6 mm and has introduced the glass in automatic glass door systems for refrigerators used in convenience stores and supermarkets manufactured by Hussmann Corporation, the U.S. refrigerator and freezer showcase manufacturer wholly-owned by Panasonic.
In April 2019, Panasonic launched production of the glass for the European housing market jointly with AGC Inc. and expanded the glass business for the replacement of existing windowpanes and other applications.
Panasonic will release the tempered vacuum insulated glass in the first half of the next fiscal year that starts April1, 2020 in addition to the float vacuum insulated glass(*3) the company has been offering.
Vacuum insulated glass is manufactured by vacuum-sealing two sheets of glass with vacuum sealing material melted at high temperature, while tempered glass generally drops in strength when it is heated at high temperature.
Panasonic newly developed its proprietary “Super-low-temperature sealing material” and consequently achieved the sealing of tempered glass in a temperature zone in which it does not drop in strength.
The technology capable of manufacturing both the float(*3) and the tempered vacuum insulated glass is Panasonic’s proprietary technology.
