Tempered Vacuum Glass is based on the tempered glass filled in vacuum between two glass panes or triple panes, which is the only new energy conservation material in the world that can effectively insulate against radiation, convection and conduction. On behalf of this, our company ICESUN� Vacuum Glass� LTD. has launched kinds of products like� Wind Resistant Vacuum Glass,� Anti-Radiation Vacuum Glass,� Thermal Insulation Vacuum Glass, etc. Tempered vacuum glass consists two panes of glasses which are separated by an array of supporting pillars and welded together by glass at very low temperature. Vacuum between glass is 10-4Pa, where the heat convection does not exist, the heat conduction drops to minimum, with the LOW-E layer reflecting more than 95% of the infrared radiation, so the heat between the inner and outer glass plates can not be exchanged, and the excellent heat insulation effect is achieved. Tempered vacuum glass size: maximum 3000 x2000 mm; minimum 200 x200 mm; thickness 6~20 mm. Features of ICESUN vacuum glass: Sound insulation performance; Heat resistance; Thermal insulation; Sun proof function; Anti-condensation function; Low-e anti-radiation function; Long lifespan up to 50years; Wind resistance; Photochromic glass; Fireproof and bulletproof performance; Unique vacuum eye technology; Unique low temperature welding technology
