[0002] Glass curtain walls have been introduced into my country for more than 40 years. Due to their standardization, industrialization and aesthetic presentation different from traditional buildings, they cater to the needs of China's rapid urbanization and have been vigorously developed. They are also synchronized with the booming construction industry in my country, so their application speed and scope are relatively wide. However, the promotion of curtain wall technology is relatively slow, and it is also a relatively low-end special project.
