Passive Houses, Heritage Buildings, and Skyscrapers: How Vacuum Insulating Glass Fits Everywhere
Vacuum Insulating Glass: The Next Frontier in High-Performance Glazing Inside the breakthrough technology set to redefine what windows can do and why the Insulating Glass Window Market is paying close attention Introduction: Beyond the Gas-Filled Gap For decades, the dominant paradigm in high-performance window design has been the insulated glass unit (IGU) two or three panes of glass separated by a sealed cavity filled with argon or krypton gas. This technology has served the industry well, producing windows far superior to single-pane predecessors. But physics has limits: there is only so much insulating performance you can extract from a gas-filled gap before returns diminish and unit thickness becomes a constraint. Enter vacuum insulating glass (VIG) a technology that eliminates the gas entirely and replaces it with something far more effective: nothing at all. A vacuum transmits virtually no heat by convection or conduction, making it the ultimate thermal barrier. T...
