Low-e glass classification:
Single Silver Low-E Glass
Single silver low-E coated glass usually contains only one functional layer (silver layer), plus other metal and compound layers, and the total number of film layers reaches five layers.
Double Silver Low-E Glass
Double-silver Low-E coated glass has two functional layers (silver layer), together with other metal and compound layers, the total number of film layers reaches 9 layers. However, the technological control of double silver low-E glass is much more difficult than that of single silver.
COMPARISON BETWEEN SINGLE SILVER LOW-E GLASS AND DOUBLE SILVER LOW-E GLASS
Any coated glass will limit the transmission of visible light to varying degrees while limiting the transmission of solar thermal radiation. Double-silver Low-E glass can block more solar radiation heat energy than single-silver Low-E glass. In other words, in the case of the same transmittance, Double Silver Low-E has a lower sunshade coefficient Sc, which can filter sunlight into a cold light source to a greater extent.
The heat transfer coefficient of double-silver low-E glass is lower than that of single-silver low-E glass, which can further improve the thermal insulation performance of outer windows and truly achieve warm winter and cool summer. Simply put, because the double silver low-E glass greatly reduces the heat exchange between indoor and outdoor environment through glass, when the air-conditioning heating or cooling, when the indoor temperature reaches the set temperature, the air-conditioning can stay on standby for a longer time, thereby saving power consumption.
