Panasonic Develops Unique Vacuum Insulated Glass Based on Its Plasma Display Panel Technology
2017/12/06

The new vacuum insulated glass achieves the industry’s top-class(*1) insulation performance for glass of approx. 6 mm total thickness

Osaka, Japan - Panasonic Corporation today announced it has developed and succeeded in mass production of thin, high-performance vacuum insulated glass by applying technologies the company accumulated in the development and manufacturing of plasma display panels (PDPs). The glass achieves a heat transfer coefficient (Ug value) of 0.7 (W/m2K)(*2), the industry’s top-class(*1) insulation performance for glass with a total thickness of 6 mm, which is equal to or greater than triple glass containing argon gas(*3) with a total thickness of about 3 cm.

A PDP displays an image by causing phosphors to emit light within an extremely thin vacuum layer between two sheets of glass that are vacuum-sealed. Generally, to maintain the vacuum state within the glass, vacuum sealing material technology is required to suppress emission of gas from the substances inside the vacuum layer while maintaining a high vacuum state. Panasonic has retained the vacuum glass panel manufacturing technology and lead-free vacuum maintaining material technology that it cultivated during the development and manufacture of PDPs.
