Hollow glass blocks, a new trend in modern architectural decoration, have been widely recognized for their unique aesthetics and practicality. Made from inorganic silicate minerals such as high-grade glass sand, soda ash and quartz powder, and fired at high temperatures, these bricks are non-toxic, harmless and non-polluting, making them an environmentally friendly product. The closed internal cavity structure gives hollow glass blocks many excellent properties such as light transmission and opacity, sound insulation, heat insulation, heat preservation, moisture resistance, dust prevention and anti-condensation. In addition, hollow glass blocks are also durable, corrosion resistant and easy to install, making them an ideal decoration material for the home.
