Tungsten oxide nanopowder may be applied to manufacture an environmentally-friendly and energy-saving building glass thermal insulation coating. As you may have known, in the past, domestic traditional methods to solve the problem of heat insulation of glass doors and glass windows were mainly - heat-insulating film, heat-reflecting film and LOW-E glass. But these products have poor light transmittance. And they are easy to cause light pollution. Besides, the prices of these materials are three or four hundred RMB per square meter or more, which make it difficult for the public to accept. And therefore it is difficult to popularize.

Therefore, experts and scholars said, it is necessary to explore an energy-saving product that can be used for heat insulation in the hot summer and heat preservation in the cold winter on common single-layer glass. It not only reduces the use of glass, saves raw materials, reduces building load, but also better solves the energy-saving problems of glass doors and windows. After years of exploration, experts have discovered the unique optical properties of tungsten oxide, and found that its nano transparent thermal insulation coating has excellent anti-ultraviolet and near-infrared shielding properties, which can play a good thermal insulation and heat preservation effect.
