Vacuum Insulated Glass
Vacuum insulated glass (VIG) is a type of glazing that uses a vacuum between two panes of glass to insulate a building. Our vacuum glass supplier provides VIG that is much more efficient than traditional double- or triple-paned glass, and can help to reduce energy costs by up to 30%.

VIG is made by creating a vacuum between two panes of glass. The panes of glass are then sealed together to create a hermetic seal. The vacuum prevents heat from transferring between the two panes of glass, which makes VIG much more efficient than traditional glazing.
