What is Vacuum glass?

Different from insulated glass,vacuum insulating glass panels are sealed panels with 0.3mm vacuum space at 10^(-4)Pa.

Taking advantage of micro pillars and advanced low temperature metal sealing technology,vacuum insulating glass will finally replace traditional insulated glass and bring more comfort to your life.

  • More comfort

  • Thinner and Lighter.

  • Low carbon emission.

  • Sustainable development

Solar solutions

Combine with solar industry,vacuum 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 glass helps keeping heat and water temperature in winter .

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