低辐射玻璃也称为Low-E玻璃,Low-E玻璃可以采用真空磁控溅射方法在玻璃表面上镀上含有一层或两层银层的膜系,这种称之为离线Low-E玻璃;也可采用化学气相沉积方法在玻璃表面上镀上半导体氧化物(譬如:掺氟的氧化锡等)的膜系,这种称为在线Low-E玻璃。Low-E玻璃的表面辐射率很低。在线Low-E玻璃的表面辐射率低于0.20,离线Low-E玻璃的表面辐射率低于0.15。它的主要功能是降低室内外远红外线 Low-E glass also known as Low-E glass, Low-E glass vacuum magnetron sputtering method can be coated with glass containing one or two layers of silver film system, which is called offline Low-E Glass; also can use the chemical vapor deposition method on the glass surface coated with semiconductor oxide (such as: fluorine-doped tin oxide, etc.) of the film, this is called online Low-E glass. Low-E glass surface emissivity is very low. The surface emissivity of online Low-E glass is less than 0.20 and the surface emissivity of offline Low-E glass is less than 0.15. Its main function is to reduce indoor and outdoor far-infrared rays
