• Thermal insulation function of low e coating

    In the mid-1970s, it was discovered that most of the heat transfer of double glazing was caused by infrared radiation exchange from one layer of glass to another. Therefore, as long as the emissivity of any one of the double glazing is reduced, the heat transfer can be greatly reduced. This is the reason for LOW-E glass. There is data showing that the clear float glass has an emissivity of 0.84 and the low e coated glass with an emissivity of 0.2 reduces the…
