Nano particle size cesium tungsten oxide may be used to prepare a thermal insulation film. And the obtained thermal insulation film can effectively reduce the solar thermal energy transmitted to the room through the glass. In other words, attaching a layer of heat insulation film of cesium tungsten bronze nanoparticles to the architectural glass can effectively control the amount of solar energy. Compared to un-filmed architectural glass, the coated glass blocks most of the heat from entering the room.

This is because ordinary glass can only block a very small part of the ultraviolet rays. Thereby, it can not effectively protect the human skin indoors. While the heat insulation film of nano grain size cesium tungsten bronze can block more than 99% of ultraviolet rays, helping you to do indoor sun protection work. According to the data, after the thermal insulation film of the building is attached, the indoor temperature can be significantly reduced by 3°C~5°C, and some can even be reduced by 7°C.
