What is Low-E glass?
Low-E energy-saving glass (Low-Emissivity glass) is a coated glass coated with multilayer compound medium layer and functional and non-functional metal film on the glass surface, so that it has high transmittance of visible light and high infrared reflectivity. Low-E glass can help to limit heat gain and thermal energy transfer.
What's the differences of triple, double, single silver low E glass?
In the film layers of Low-E glass, the silver layer is the functional layer. The more silver layers, the better the effect.
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.
