Yellow tungsten oxide nanopowder may be applied to a new energy efficient glass such as energy-saving glass curtain wall, which is environmentally friendly of great importance in building renovation. Some experts have conducted experiments on the heat insulation effect of common insulating glass and tungsten oxide smart glass. The test results show that:

The ordinary insulating glass is heating up to a temperature of more than 10°C in one minute under infrared irradiation. While the smart window of tungsten oxide nano particles in a colored state (light blue) is heating up to less than 2°C in one minute under the same infrared irradiation. This is because the new energy-saving material tungsten oxide nanoparticles have excellent optical properties, so the downstream product energy-saving glass can shield more than 98% of ultraviolet rays and 97% of infrared rays, and do not affect the passage of visible light. In addition, in the winter, compared with ordinary glass, this transparent glass can block the heat overflow with good heat preservation effect.
