Nano WO3 may be used to produce a heat-insulating energy-saving glass. This new type of environmentally-friendly and energy-saving glass can not only shield heat and keep warm, thereby reducing the load of air conditioning. In other words, the thermal insulation glass of tungsten oxide helps China's green development through energy conservation and emission reduction.

Experts said that it is the tungsten oxide nanoparticles that enable the glass to be self-regulated according to changes in ambient temperature, achieving "warm winter and cool summer", while greatly reducing the power consumption of the air conditioner, and therefore the energy conservation and emission reduction targets can be achieved. Such energy-saving glass doors and windows can save energy by more than 40%. And the temperature difference between indoor and outdoor can reach 8°C. Also, it shields more than 99% of ultraviolet rays and 90% of infrared rays. And the light transmittance is over 70%. Experts hope that through their unremitting efforts, this new energy-saving insulation product will be extended to families all over China and around the world.
