Soft Coating Low E Glass

Low E means 'Low Emissivity' emissivity is defined as the amount of radiation emitted or absorbed from a surface.

Soft coating Low-E glass also called off line LOW E glass is one of the coated glass products with various metal or other compound depositions on float glass through vacuum magnetron sputtering technology. It has different transmittance to visible light and higher reflectance against far Infrared. It provides natural light transmission while helping to limit heat gain and thermal energy transfer. Due to continuous improvements in its thermal insulation and solar control performance, glass is a flexible building material that can help improve the energy efficiency of buildings.

What this has meant is an explosion of Low E options that can be tailored to meet various building requirements across the world. The options will vary from tuning for reducing heat loss in cold climates to solar control to stop buildings overheating in warmer climates. Some climates require both performance attributes

Low E coatings can also be coloured, reflective, and or applied to Tinted Float glass to further enhance the performance and or the look of a building.

Any coating applied to the surface of the glass will have some effect on the overall clarity and this has been an important consideration in the development of modern Low E products – obtaining maximum performance with minimal optical impact.

There is single silver LOW E, double silver LOW E, triple silver Low E coated glass and related Compound glass products with optimized performance for customers according to the actual demands and requirements of different climate zones.

• Architecture: curtain wall, house decoration, facade, windows and doors, furniture
• Industrial field: microwave oven, refrigerator doors, liquor cabinet, Beverage display cabinet, disinfection cabinet and other various commercial display cabinets.

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 and 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.

(1). Triple silver Low E glass ( Solarban series)

Characteristics:

---Excellent shielding function for infrared thermal, greatly improve the

indoor comfort.

----Technology from PPG, Suitable for remote temperable triple silver LOW E glass.

---LSG value can be 2.37, perfect combination of sunlight control and

visible light transmission

---Excellent processability, it can be incurve and excurvature

What's the difference of single silver, double silver,triple silver LOW E 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.
