Panasonic Plasma Display Panel Technology lives on in Unique Vacuum Insulated Glass first to be used in retail fridge and freezer doors. Panasonic 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 new vacuum insulated glass achieves the industry's top-class insulation performance for glass of approx. 6 mm total thickness, achieving comparable insulation of argon filled triple insulated glass of 3 centimeter thick. The vacuum glass achieves a heat transfer coefficient (Ug value) of 0.7 (W/m²K)(*2). This way the window frame becomes the conducting area.

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.

Now, Panasonic has realized a practical vacuum insulated glass with excellent insulation performance by developing a new slim-model gas adsorbent that adsorbs the gas that occurs within the vacuum layer, and a new low thermal conductive component that forms a 0.1 mm gap between the two sheets of glass. Due to the unique manufacturing method the company developed, the exhaust hole sealing component required to form the vacuum space is not present on glass surface, which gives a smooth, flat product appearance. Furthermore, this product uses no lead, a hazardous substance, ensuring safety and environmental friendliness.

This new vacuum insulated glass will be first used by Hussmann Corporation, the U.S. refrigerator and freezer showcase manufacturer wholly-owned by Panasonic, prior to commercialization. Hussmann will use the glass for automatic glass door systems for walk-in coolers and freezers in convenience stores and supermarkets to address tightened regulations by the United States Department of Energy.

Panasonic plans to offer the glass as part of its insulation solutions in Japan and overseas to respond to the global trend toward stricter emission regulations, as seen in the Paris Accord, and help achieve a sustainable society.
