Yellow tungsten oxide may be used to prepare a transparent heat insulation glass coating. Such architectural glass transparent coating not only shields harmful light (ultraviolet rays) and high-heat rays (infrared rays) into the room in summer, but also shields heat loss in winter, directly bringing the temperature difference between indoor and outdoor to 3-6°C, thus realizing "cool in summer and warm in winter".

Tungsten oxide may be used to produce a transparent heat insulation glass coating, which is environmentally friendly for promoting the construction of green building. We all know that glass is widely used as architectural glass windows, glass doors, glass curtain walls, glass domes and automotive glass windows, so solving the thermal insulation problem of glass will have a significant contribution to the world's energy conservation.

Tungsten trioxide may be used to prepare a new type of transparent heat insulation glass coating. The obtained coating, which overcomes the shortcomings of the existing glass thermal insulation coating, has good transparency to visible light, and has good reflection, shielding and absorption effects on near-infrared and ultraviolet light. Such coating also has strong adhesion, high hardness, high scratch resistance, high temperature resistance and high aging resistance. Besides, it is waterproof and antifouling.

WO3 nanopowder may be applied for preparing heat-insulating energy-saving glass. As early as a few years ago, the Ministry of Industry and Information Technology promoted the preferred product of green building materials - energy-saving glass and the standard seminar on energy efficient glass was held in Beijing. It marks the building energy efficiency and green building demand as the traction, the construction of the standard system as the starting point, and the promotion of the transformation and upgrading of the building materials industry to promote the green building materials, has entered the stage of landing.
