Windows Are Changing — This Glass Insulates Like a WALL

What if your windows were barely thicker than a single pane, but kept the heat in almost like triple glazing? 🪟 Vacuum glass puts a gap about as thin as a sheet of paper between two panes, with almost all the air pumped out. No air means two of the three ways heat escapes through a window simply stop working. The idea was patented in 1913, but nobody could build one until 1989. In this video we explain why: the tiny pillars holding the glass apart against 10 tonnes of air pressure, and the edge seal that has to stay airtight for decades. We also look at what’s on the market today, what it costs compared with double and triple glazing, and who should actually consider it. Would you pay extra for windows this thin?
