Our vacuum glass is based on the proven vacuum thermos bottle. By separating two panes of glass with small pillars and sealing the edges, a micro-void space is created between the two panes. All of the air is removed. The height of the void space between the panes is kept 0.2 mm by the tiny pillars, and the vacuum is pulled down to 10-4 Pa.
Due to the inside vacuum, the conduction and convection of heat between the panes is almost nil. In addition, the LOW-E coating reflects more than 85% of the infrared back into the room. For these reasons, our vacuum glass windows prevent nearly all heat loss from conduction, convection and radiation. ICESUN glass provides a beautiful window and a superb thermal barrier.
VIG is warrantied for quality for 10 years after manufacturing, in the condition of being treated under guidelines. Longer warranty is required extra pay.
When the vacuum is lost in its service time, the vacuum-mirror would disappear, new VIG will be provided for replacement at free.
