Guardian Industries, an architectural and automotive glass manufacturer, recently unveiled a new prototype glass product that could provide some big energy gains when integrated into the homebuilding process. The windows of your house may soon actually supply energy via passive solar gains instead of leak it.

The vacuum-insulated glass (VIG) panel consists of two glass panes, one of which is covered in low-e coating. When vacuum sealed together, the panel effectively eliminates both convection and conduction of heat. The most impressive aspect of the product is its potential level of insulation (or R-value). The higher the R-value, the better the insulation. Most low-e glass comes in between R-2 and R-4, but this revolutionary glass promises a whopping R-12 to R-15 rating – the equivalent insulation of your home’s exterior walls.
