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.
Are you still confused?
What’s the differences of triple, double, single silver low E glass?
How can I choose?
Follow me.
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.

Notes: 1. Above performance data are calculated according to stadards NFRC 2010, EN673 and JPG151. 2. The performance data are only for reference. Jinjing will hold the right of final interpretation. 3. Light-to-solar gain (LSG) ratio is the ratio of visible light transmittance to solar heat gain coefficient. 4. The make-up with argon means the cavity is filled with a 90% argon+10% air mixture. |
