The double-silver low-radiation glass is characterized in that a silver film layer is added on the basis of common single-silver low-radiation glass, and compared with the single-silver low-radiation glass, the double-silver low-radiation glass has higher reflectivity to infrared rays and stronger heat insulation performance while keeping higher transmissivity to visible light. The film layer structure of the double-silver low-emissivity coated glass produced by adopting the vacuum magnetron sputtering method is generally glass/a base dielectric layer/a first functional silver layer/a first barrier layer/an intermediate dielectric layer/a second functional silver layer/a second barrier layer/an upper dielectric layer and the like.
