在浮法玻璃原片上采用真空磁控溅射方法镀一层或多层纳米级金属银层而成。该产品对可见光具有较高的透射率，对红外线有较高的反射率，因此具有良好的隔热性能，节约能源的同时使建筑物实现冬暖夏凉。

It is made by plating one or more layers of nano-sized   metallic   silver   layer   on   float   glass   sheet   by vacuum magnetron sputtering method. The product has high transmittance for visible light and high reflectivity for infrared rays, so it has good thermal insulation performance, saving energy while making the building warm in winter and cool in summer.
