Next step for windows: vacuum insulated

Vacuum instead of inert gases - with this technological development, glazing could take another great developmental stride. However, at 10 tonnes per square metre, the atmospheric pressure on evacuated flat glazing is immense. And for evacuated glazing, the same applies as for vacuum panels: only a lasting vacuum guarantees good thermal insulation. Now, this research project is to provide evidence that evacuated glazings with special functional layers are technically feasible for architecture.
It is estimated that the price of evacuated glazing will be comparable to that of triple glazing today, i.e. approximately 80 euros per m².
