Nano grain size yellow tungsten oxide is a transparent thermal insulation material that may be applied to the glass of buildings or vehicles. That is because the yellow tungsten oxide heat insulating material may effectively shield infrared heat radiation and absorb ultraviolet rays without changing the visible light transmittance of the glass. And it also takes the integrity and aesthetics into consideration.
The application of this kind of transparent thermal insulation coating on glass is mainly achieved by combining the following two technologies - tip nanotechnology and micro-layer coating technology. According to the experimental data, if the surface of the glass is coated with a transparent film with a thickness of about 20μm, the indoor temperature difference before and after the glass coating reaches 6-8°C. The performance is even better before and after noon with the strongest sunshine and strongest heat insulation demand. This type of thermal insulation material greatly reduces the power consumption of air conditioning, which saves energy about 35%. It means that the heat insulation effect is remarkable.
