Tungsten oxide may be used to prepare a transparent heat-insulating energy-saving film. In the hot summer, the new environmentally friendly heat insulation film can reduce heat inflow to reduce the use of air conditioning, thereby reducing electric charge and improving energy efficiency.

The smart film of nano particle size of tungsten trioxide can also shield 99% of ultraviolet rays, greatly reducing the heat of the sun entering into the room, without affecting the passage of visible light. Also, such thermal insulation film protects the interior of the building from damage and reduces the harm to the body.
In addition, the tungsten trioxide heat insulation film can also improve the indoor environment, that is, improve indoor comfort, relieve heat and glare. Another important performance is security. Common glass will be damaged in the event of strong winds, heavy rain, and impact, resulting in a large amount of glass fragments, causing harm to people and property. When the tungsten trioxide smart film is attached to the glass door and window, even if the glass has been broken into pieces, it will be bonded into a whole, which greatly improves safety.
