Consists of one piece of float glass and one piece of Low-E Glass, there are tiny spacers to form a gap between two glass plates with a vacuum space 0.2mm. All edges are sealed by frit frame to enclose the space. Insert a tube connected to this space for degassing. Seal the tube after degassed, this panel is formed as a Low-E vacuum glass.

Specification: (mm)

Glass Thickness: 3.2+3.2 ~ 8+8

Vacuum space: 0.2

Max. size: 3600×1800

Min. size: 500×500

Benefits:

1. Window Frame Cost Saving: thickness is much thinner which can save architectural cost. (Also for narrow window frame design, Vacuum glass is best choice.)

2.Low U value: significantly reduce power consumption for air conditioning and the pollution and greenhouse gas emissions for a better environmental protection with energy saving and emission reduction.

3. Heat Insulation: in hot summer, effectively block solar heat and keep interior cool; in cold winter, possess high performance of heat loss insulation, keep interior warm and comfortable.

4. Soundproofing: vacuum space effectively blocks noise transmission and reaches sound transmission class by 39dB.

5. Long service life: install getter material inside to maintain vacuum level stable and protect Low-E coating for a long service life.

6. Anti-Dew-Forming: When outdoor temperature lowers to a certain level, the inner surface of anneal window glass will be dew-forming.

Dew-forming temperature of Low-E vacuum glass is relatively low, the lowest condensation temperature of Low-E Vacuum Glass about -40ºC without inner dew-forming situation.
