Hollow tempered glass
Insulating glass is between glass and glass, leaving a certain gap. The two pieces of glass are separated by an effective sealing material seal and spacer material, and a desiccant that absorbs moisture is installed between the two pieces of glass to ensure that the inside of the insulating glass is a dry air layer for a long time without moisture and dust. . It has good thermal insulation, heat insulation, sound insulation and other properties. If various diffused light materials or dielectrics are filled between the glass, better sound control, light control, heat insulation and other effects can be obtained
