Energy Efficient Low-E Coated Glass

Energy Efficient Low-E Coated Glass

Jinjing is one of the few manufacturers in the world that produces both online (hard coated) Low-E and offline (soft coated) Low-E glass.

Jinjing adopt the world’s most advanced Low-E coating production line from Leybold Germany, with annual capacity of 10 million square meters, which can provide customers with the high-performance triple silver, double silver, single silver Low-E glass as well as compound glass products. Relying on global leading technology of PPG America, through independent R&D and innovation, Jinjing has become the first manufacturer in China to supply off-site temperable triple silver Low-E glass.

Why Choose Low-E glass? How does it save energy?

image4

Low-E glass refers to glass with a low emissivity coating. It reduces heat gain or loss by reflecting long-wave infrared energy (solar heat), therefore decreases the U-value & solar heat gain and improves the energy efficiency of the glazing. Because of its relative neutrality in appearance and energy efficiency, low-E glass is widely used in residential and commercial buildings and is expected to continue to increase in usage in the coming years.

What’s the difference between soft coated and hard coated Low-E glass?

Low-E glass is made of low emissivity coating film on the surface of glass by physical or chemical methods. At present, the mature technologies for commercial manufacturing of Low-E glass include vacuum magnetic emission (physical method, also called offline Low-E glass & soft coated Low-E glass) and chemical vapor spraying process (chemical method, also called online Low-E glass & hard coated Low-E glass).

What’s the difference between soft coated and hard coated Low-E glass?
ITEMS soft coated hard coated
Production Process 1. Vacuum magnetic sputtering emission
2. Completed in an independent coating glass production line
3. Multilayer composite coatings on glass surface
1. Chemical vapor deposition
2. Finish coating in tin bath of float line
3. Single layer coating
Film Structure  1  2
Variety of Appearance & Performance Rich product series: large selection range of appearance color and performance data The product series is simple: the appearance color and parameter are relatively fixed with limited selectivity.
Film Stability & processability 1. The film is easy to be oxidized and can be stored for 1-2 years after professional packaging;
2. It can't be used in a monolithic piece, it must be used after insulating, and the coating is in the insulated cavity;
3. Special case: Jinjing triple silver products can be used in laminated glass , and the coating can contact the coating directly
1. The coating is sintered with glass, which is very hard and stable. It is stored as common float glass;
2. It can be used in a monolithic piece; It is easy to be processed and the processing method is the same as ordinary float glass

In the graph, these are three solar spectral transmittance curve of triple, double, single silver Low-E glass with similar visible light transmittance. The middle area of the vertical line is the area of visible light (380-780 nm), and the visible light transmittance of the three kinds of Low-e is similar. The right area of the vertical line is infrared ray area (780-2500 nm). Since most of the heat is carried by infrared rays, the area under the curve reflects the heat energy which the solar energy goes directly through the glass. The single silver Low-e contains the largest area, double silver Low-E takes second place, and the triple silver Low-e takes the smallest area which means the least heat goes through the glass, and best thermal insulation performance.

In the graph, these are three solar spectral transmittance curve of triple, double, single silver Low-E glass with similar SHGC value within 380-2500 nm. The SHGC value is similar, which means the contained area of the three coated glass is similar, but the distribution shape of the curve is obviously different, and the triple silver Low-e takes the smallest area which means the least heat goes through the glass. With similar SHGC value, the triple silver Low-e shielding capability of infrared thermal radiation is much greater than that of double silver and single silver Low-e glass, which greatly improved the indoor comfort in summer.
