Nano tungsten trioxide may be applied to prepare a smart window heat insulation coating, which is non-toxic and non-irritating, so it will not pollute the home environment and not cause harm to the human body. Such coating is transparent with advantages of good heat insulation so that it will not affect the transparency of the architectural glass, that is, it will not affect indoor lighting.

Therefore, with the development of green buildings and the use of glass curtain walls, thermal insulation coatings of nano tungsten trioxide have become the mainstream environmentally friendly coating with advantage of energy consumption reduction. It may improve the home environment and make the home glass more beautiful and atmospheric. It may also improve the comfort of the human body by shielding most of the infrared rays and ultraviolet rays. And therefore you will not feel glare when you are looking directly at the sun through such thin thermal insulation coating. Besides, it is easy to construct by a very simple spraying process. You can spraying the coating by yourself - just clean the glass, dry, and spray the coating on the glass surface with a watering can.
