√Low emissivity coated glass (Low-E glass) is coated with low emissivity material silver and metal oxide film on the surface of glass to make the glass present different colors.

√In order to improve the energy-saving properties of the glass, the U value of the glass is reduced and SC is selectively reduced.

√High infrared reflectance can directly reflect far-infrared thermal radiation; low surface emissivity E has little ability to absorb external energy, so less heat can be re radiated; the shading coefficient SC has a wide range, so the transmission of solar energy can be controlled according to the needs to adapt to the needs of different regions.
