Nano WO3 may be applied to thermal insulating glass in the form of a heat-insulating film. Whether it is used on the architectural glass or on the automotive glass, the obtained transparent heat-insulation glass has good heat insulation effect and does not affect the passage of visible light. Specifically, the ultraviolet shielding rate is higher than 97%, the infrared blocking rate is higher than 90%, and the visible light transmission rate is higher than 70%.

For example, the new tungsten trioxide nano heat insulation material can be applied to the micro-hollow door and window renovation scheme. On the basis of the existing door and window glass, a piece of heat-insulating coated glass is combined to form a micro-hollow structure with the existing door and window glass, which has the effect of high heat insulation in hot summer and high heat preservation in cold winter, thereby reduce energy consumption in building operations, improving the comfort of people in the buildings. Certainly, the transparent thermal insulation coating of tungsten trioxide nanoparticles can also be directly coated on the glass to form a thin and transparent thermal insulation film. And the heat insulating effect of the heat insulating glass obtained by this scheme is not worse than that of the above scheme.
