Tungsten oxide has electrochromic property so that it may be used to prepare a high-performance energy-saving glass. And therefore it is often applied in architectural glass doors, windows or glass curtain walls. According to experts, unlike ordinary glass, such glass can automatically adjust the transparency of the glass in accordance with the change of temperature, effectively shielding ultraviolet rays and infrared rays, and thereby saving energy consumption by about 10%.

Experts explained that tungsten oxide nano particles are presented in the form of a thin heat insulation film. It is a new type of smart film that can be directly attached to ordinary glass, which not only meets the energy-saving transformation of the existing buildings, but also meets the individual needs of consumers. When this thin layer of smart film is in a light blue state, it can shield more than 98% of ultraviolet rays and more than 97% of infrared rays, and the heat insulation effect is much better than many other heat insulating curtains.
