Vacuum Insulating Glass

Revolutionary  vacuum insulating glass helps world carbon reduction and sustainable development.


What is Vacuum glazing?

Different from insulated glass,vacuum insulating glass panels are sealed insulated panels containing 0.15mm- 0.3mm internal vacuum space , 10^(-4)Pa high vacuum degree ensures excellent thermal property and soundproof performance.

Vacuum double glazing will help creating comfortable living environment,reduce carbon emission and contribute to sustainable development.

Solar solutions

Combine with solar industry,vacuum insulating glass can not only save energy,but also generate solar energy combine with solar glass.

  • Solar collectors: Replacing the 3.2mm monolithic glass panels, vacuum insulated glass helps keeping heat and water temperature in winter .

  • Insulated glass panels with vacuum glazing and BIPV glass,especially Cdte solar glass, laminated glass with solar cells, the glass keep interior confortable temperature and generate solar power.
