World's first vacuum glass Spacia Cool has vacuum layer of 0.2 mm between two sheets of glass, and has achieved about six times higher heat insulating performance than float glass, about three times higher than general insulated glass by the effects of the vacuum layer and Low-E glass. Since solar thermal radiation through the window will also be reflected back, cool living environment during summer and warm living environment during winter contribute towards energy-saving.
