Yellow tungsten oxide may be used to prepare a new type of high-performance energy-saving glass. So, what is an energy-saving glass? An energy-saving glass must have two energy-saving features: heat preservation and heat insulation.

WO3 may be used to prepare an environmentally friendly and energy-efficient glass. This is a new type of transparent energy-saving glass with high transmission of light, high heat insulation and high heat preservation. With a film thickness of only 6mm, the glass can shield 90% of infrared light under strong sunlight. At the same time, it can maintain a high visible light transmittance of 70%. In a word, the energy-saving index of such glass has set a new world record.

WO3 may be used to produce a new energy efficient glass. The obtained glass is unique in that it can shield more than 90% of the near-infrared rays that generate heat. At the same time, the visible light transmittance can be maintained above 70%. And the light-to-heat ratio is greater than 1.36. This index is leading at home and abroad.

Tungsten trioxide nanopowder may be used to prepare a transparent energy-efficient coating and thus be applied to architectural glass to obtain environmentally friendly and energy-efficient glass. Although, at present, China has not yet issued specific standards and indicators, the term energy-saving glass has already been known to all in the industry.
