The ultra-high insulation vacuum glass "Super Spacia(R)" has won the Energy Conservation Grand Prize for the fiscal year 2017.

Nippon Sheet Glass Co., Ltd. (Minato-ku, Tokyo, President and CEO Shigeki Mori) has recently received the Minister of the Agency for Natural Resources and Energy Award at the 2017 Energy Conservation Grand Prize (Product and Business Model Category) for its ultra-high insulation vacuum glass "Super Spacia®."
This award marks the third time for a vacuum glass product, following the vacuum glass "Spacia®" (1998) and the multi-layer vacuum glass "Spacia 21® Heat Shield Clear" (2013).
The ultra-high insulation vacuum glass "Super Spacia®" is our new product launched in October last year. Compared to the conventional vacuum glass "Spacia®," it has improved insulation performance by approximately 54% (achieving a thermal transmittance of 0.65 W/(m²·K)). Despite being only 10.2 mm thick, it achieves insulation performance equivalent to or better than 50 mm thick glass wool used as insulation material.
The award-winning product will be on display at our booth in the award corner of "ENEX 2018, the 42nd Exhibition on Earth Environment and Energy Harmony," held at Tokyo Big Sight from February 14 (Wednesday) to 16 (Friday), 2018 (organized by the Energy Conservation Center, Japan).
