Energy-saving glass usually refers to thermal insulation and solar shading performance of window. After the application of this type of glass can significantly reduce the power consumption of residential and office buildings, save the use of air conditioning, heating. In the winter, can significantly reduce Interior heat to escape in summer to reduce sunlight into the room. According to the information reported energy statistics from around the world, in heating and air conditioning use during which 40% energy is used for temperature control in buildings. Traditional architectural glass is difficult to meet the requirements of energy saving, gradually replaced by many versatile glass products. Most widely used colored glass (blue, Brown, green) coated glass and tinted glass, coated glass and float glass substrate is compoundedInsulating glass。 Characterization of glass insulation, shading of the physical units are: thermal conductivity, shading coefficient, Sun coefficient, reflectance, transmittance, absorptance, and so on. Is commonly used to assess the situation of indoor and outdoor heat by thermal conductivity. It represents a unit area, indoor and outdoor temperature by 1 degree by the heat. In the international system of units, thermal conductivity is measured in W\/m2K. Shading coefficient of shading the relative energy of the glass transmission values and 3mm the ratio of the relative energy value of transparent glass. Sun gets rate coefficient represents the sun heat through glass.
Energy-saving glass include: insulating heat-insulating glass, Sun protection glass, low-e glass, and so on.
