What is vacuum glass?
Vacuum glass is to seal the surroundings of two pieces of flat glass, and then evacuate the gap between them. There is no air in the space, so there will be no heat conduction and convection, which has the effect of super heat insulation and sound insulation. The gap of the vacuum layer is usually 0.15mm-0.3mm.
Joy Shing Glass has special-shaped vacuum glass production technology: Flat special-shaped vacuum glass, curved special-shaped vacuum glass.

Advantages of vacuum glass
1. Sound insulation:
The weighted sound insulation of vacuum glass reaches 39 decibels, and the weighted sound insulation of general insulating glass is about 28 decibels
2. Insulation:
The U value can be as low as 0.48W/(m-K), and the heat insulation effect of 8.3m thick vacuum glass exceeds that of 1.5m thick brick wall.Joy Shing vacuum glass effectively isolates heat transfer, and its thermal insulation performance is 2-4 times that of insulating glass and 6-10 times that of single glass.
3. Anti-condensation:
There is no gas inside the vacuum glass, so there will be no "internal condensation and fogging"
