What is Low-e vacuum glass?
Low-e vacuum glass is to seal the surroundings of two pieces of flat glass, evacuate the gap and seal the exhaust hole. The minimum gap between the two pieces of glass is 0.15mm. In order to achieve better heat insulation performance, one of the glass uses Low -e glass.
Joy Shing Low-e vacuum glass has become a new generation of high-performance glass,which has the advantages of ultra-thin, heat insulation, sound insulation, anti-condensation, energy saving, and long life.

Advantages of low-e vacuum glass
1. Insulation:
The vacuum layer effectively isolates air convection and heat transfer, and the Low-E glass significantly reduces the radiation heat transfer between two pieces of glass.The thermal insulation performance of vacuum glass is about 6-8 times that of single glass, and 4-6 times that of insulating glass
2. Anti-condensation:
Due to the high heat insulation performance of vacuum glass, it is difficult to dissipate the indoor heat, and the surface temperature of the glass is higher than the dew point, so it is not easy to generate condensation.
3. Low noise:
The vacuum layer of the vacuum glass effectively isolates the sound transmission. The sound insulation of single vacuum glass can reach 39dB, and the sound insulation of composite vacuum glass can reach 42dB.
