ICESUN Vacuum Glass LTD. provides Energy Efficiency Vacuum Glazing for Windows and Doors. Our energy efficiency vacuum glass is separated by a 0.2mm high support, and the edges of the two panes of glass are sealed with low temperature glass, and the air is expelled from it. The vacuum degree between the glass is 10-4Pa, so the heat convection does not exist, the heat conduction is reduced to the limit, and the LOW-E layer reflects more than 95% of the infrared radiation, so the heat between the inner and outer glass plates cannot be exchanged, reaching the Excellent thermal insulation effect. Tempered vacuum glass size: maximum 3000x2000mm; minimum 200x200mm; thickness 6~20mm.
