What is Vacuum glass?

Different from insulated glass,the vacuum glass panels are sealed and separated by 0.3mm vacuum space at 10^(-4)Pa.

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

  • More comfort

  • Thinner and Lighter.

  • Low carbon emission.

  • Sustainable development
