The glass curtain wall heat insulation coating of tungsten trioxide nanoparticles can shield the ultraviolet rays in the range of 320nm-460nm. It simultaneously allows the visible light of 440nm-780nm to pass through. In other words, such energy-saving coating does not affect the see-through and lighting effects.

As common glass does not have the ding of shielding heat radiation and ultraviolet light, it needs to be sprayed with a transparent heat-insulating coating to form a heat-insulating film, which can shield a large part of heat and UV rays in sunlight. In addition, although we can't see the ultraviolet rays from the naked eye, the penetration of ultraviolet rays is still relatively strong. A large amount of ultraviolet rays enter the room through the glass, which will damage the furniture in the room and hurt the skin and eye health of the indoor personnel. Therefore, it is necessary to spray a layer of transparent heat-insulating coating of tungsten trioxide nano particles on the common glasses.
