Typical low-E glass contains only one layer of pure silver (functional layer), the so-called single-silver low-E glass. The total number of film layers of double silver glass reaches more than 9, including two pure silver layers. Three-silver low-E glass contains more than 13 film layers in total, including three pure silver layers (see Figure 1). Compared with single silver low-E glass, although double and three silver low-E glass processing requirements are higher, but its energy saving is much better than single silver low-E glass.
