Guardian Glass has developed innovative technology that is changing the way high performance glazings are manufactured, while meeting tomorrow’s demands for increased thermal energy performance. Guardian Vacuum IG takes two glass panes and seals them

airtight. A vacuum is created in the space between the two fully tempered glass panes, which are held apart by almost microscopic pillars. The vacuum eliminates any fill gases and all associated conduction and convection losses through the gas, resulting in a significant reduction in heat loss from the glazing unit.

Compared to standard triple insulating glass units, Guardian Vacuum IG is thinner and lighter, it has a better thermal insulating performance, a higher light transmission and a lower reflection. The thermal insulation performance remains the same regardless of the angle at which it is installed (from vertical to horizontal). The development was first deployed in retail refrigerator doors, where it creates an optimal shopping experience by providing uninterrupted views of refrigerated goods.
