aerogels. According to the relevant information, a medium silicate glass, which is called aerogel, is filled between insulating glasses, and the glass made by this process is called gel glass. The thickness of gel glass particle layer is only 16mm, the light transmittance is 45%, and the U value of heat transfer coefficient is 1., which is almost the same as that of insulating glass, and makes the light entering the room evenly distributed.
