Glass is widely used in industries such as construction, transportation, shipbuilding, aviation, and refrigeration. It is not only a good transparent material, but also a material with good thermal conductivity. Regardless of the field in which glass is applied, heat conduction through glass can lead to significant energy loss. With the development of the glass processing industry, more and more people have realized that insulating glass has significant energy-saving effects. The application of insulating glass in China is also increasing, especially with the increasing use of curtain wall structures in buildings, which further promotes the application of insulating glass. In addition, domestic and foreign practices have proven that improving the insulation performance of building envelope structures, especially enhancing the insulation performance of windows, is the most economical and effective method to prevent heat loss in buildings. Hollow glass plays a crucial role in related architectural applications.
