WO3, mainly nano particle size tungsten trioxide, is a kind of nano heat insulation material with special optical properties so that it may be applied to building glass to obtain thermal insulating glass. And the nano thermal insulating material of tungsten trioxide nano particles has the advantages of high shielding rate in infrared light region and ultraviolet light region, and high transmittance in visible light region. And therefore such heat insulation material may be applied to the surface of the architectural glass by a shower or roll coating process to obtain the heat-insulating glass.

By utilizing the transparent heat insulating properties of the tungsten trioxide nano material, the architectural glass using such heat-insulating material as a raw material can achieve the energy conservation and cooling effect in the hot summer, and the energy conservation and heat preservation effect in the cold winter. In short, under the premise of not affecting the glass lighting, the new building heat insulation glass has a significant effect on sun protection and heat insulation. In addition, the obtained architectural glass may also play a role in keeping the home products, paintings and other collectibles away from aging. In other words, it can block ultraviolet rays.
