Yellow tungsten oxide may be applied to energy-saving glass. In the hot summer, such transparent heat insulation glass can prevent ultraviolet radiation and heat radiation in sunlight to reduce room temperature. In the cold winter, such transparent heat preservation glass can block indoor heat radiation from escaping through glass doors and windows.

In this process, tungsten oxide nanoparticles are present in the form of thermal insulation and heat preservation coating. It can effectively reduce the transmission of near-infrared rays and ultraviolet rays without affecting the transmission of visible light. Before the tungsten oxide energy-saving glass appeared, there were many kinds of energy-saving glasses on the market. In terms of use, it is necessary to optimize the selection according to the geographical, climatic characteristics, building orientation, level and economic consumption level of each region. Since then, tungsten oxide thermal insulation glass is expected to replace many of the existing energy-saving glasses, as it can play the ding of several energy-saving glasses to a large extent.
