The transparent heat-insulating coating of tungsten trioxide nano particles has a shielding rate of 99% for ultraviolet light in sunlight, and can also shield about 370nm of infrared rays of about 90%. Light waves with wavelengths between 220nm and 379nm can be a serious hazard to health and damage to furniture. That is to say, the new heat insulating nano coating can prevent the human body from being invaded by infrared and ultraviolet, and can also prevent fatal damage such as aging and fading of indoor curtains, carpets, furniture and various kinds of furnishings. And therefore it creates a comfortable and healthy indoor environment that makes people's lives more exciting and comfortable. In addition, as it is an environmentally-friendly building material, the tungsten trioxide heat insulation coating does not contain toxic and harmful substances, and does not volatilize harmful gases harmful to the human body such as formaldehyde, dialdehyde benzene, and the like.
