20mm 22mm Vacuum insulated safety tempered glass for passive house window glass

 Insulating glass is made of two sheet or multi-sheet of glass, and the unites are sealed by two process of sealing with high strength together with aluminium spacer

Characteristics:

1.)Energy saving :very low u value(=1.0w/sqm k)could be less if filled with inert gas, thus ,reduce the heat transfer coefficient.

2.)Noise reduction:could reduce 30 decibels and diminish 5 decibel more if filled with inner gas.

3.)Anti-dew under even the temperatue below -70degree.

4.)Under the conditions of same insulation effect,insulating glass can be increase the lighting area, enhance interior comfort and simplity the building structure.
