Transparent Insulation · A New Era

A step-change
in building
performance.

Vacuum insulated glass is the first true breakthrough in glazing in a century — insulating like a wall in a profile thinner than double-pane glass, and cutting a building's heating energy dramatically.

8.2mm. The number
that changes the
