Adopting high-performance Low-E glass to ensure light transmittance, in the meanwhile, it has the characteristic of high reflection of medium and far-infrared rays (780-2500 microns), thus filtering the sunlight into a cold light source. With better heat transfer coefficient (U value) and shading coefficient (SC), it blocks 30-45% more solar radiation comparing to conventional low-e glass. Extremely low heat transfer coefficient, indoor comfort, reduce air-conditioning costs at the same time, greatly reducing energy loss. Low-E glass, also known as Low emissivity glass, is coated on the glass surface with multiple layers of metal oxides. Among them, the nano level silver layer can make the emissivity of the glass reduced from 0.84 to 0.02~0.12, so as to filter the sunlight into a cold light source, which not only meets the requirements of natural lighting, but also ensures a comfortable room temperature.
