Tungsten oxide for producing hotel lobby heat insulation coating is often adopting tungsten oxide nano particles with high heat insulation and high visible light transmission. It is reported that such transparent heat insulation glass coating meets the requirements of relevant industry standards. Also, it meets the three major conditions of advanced energy efficiency levels, good energy saving economics, and significant social benefits.

According to the experts, the hotel lobby heat insulation coating of tungsten oxide is applied to the glass substrate to form a coating film that has an absorption maximum at 320-360 nm (dependent on film thickness) and an onset for absorption at 400 nm. Also, the film shows good transmission from 500 to 1000 nm (60%) and some reflectivity over the same region. And it was found that after the renovation of window glass of the hotel lobby by using such heat insulation coating, the window seat in the lobby gathered many people for business talks. They said that the comfort had improved significantly.
