Tungsten trioxide for preparing French window thermal insulating glass coating refers to cesium-doped tungsten trioxide nano particles. And the prepared coating is a transparent smart coating that can change ordinary glass into energy-saving glass. At present, the energy-saving glass on the market is mainly Low-E glass. Although the technology has matured, there are still many problems. For example, it is a single piece glass, the coating is exposed to the air so that it gradually loses its energy saving ding.

While this problem does not exist for tungsten oxide nanoparticles doped with cesium. Even if its coating film is exposed to the air, its heat insulation and energy saving effect can last for a long time. Cesium-doped tungsten trioxide French window thermal insulating glass coating can be completely applied to the external glass doors and windows, reducing the energy consumption of air conditioning. So, such coating is suitable for places such as glass doors and windows, glass curtain walls and skylights for public facilities in South China.
