The numerous issues with glass curtain walls can't help but make people wonder: Are glass curtain walls really safe?
According to national regulations, safety glass must be used in glass curtain walls. To put it simply, there are two types of safety glass: tempered glass and laminated glass. Compared with tempered glass, laminated glass can be called safety glass in the true sense. Due to the fact that once the glass curtain walls in high-rise buildings are damaged, the small glass shards that fall can be quite harmful because of the characteristic of gravitational acceleration. However, when laminated glass is damaged, it is still kept in block form by the PVB film between the laminated glasses and is not easy to fall. Moreover, the causes of damage to glass curtain walls are rather complex. Based on the actual design, processing, installation, and application of each piece of laminated glass, on-site investigation, testing, and calculation analysis should be carried out to possibly obtain a more scientific and accurate cause. In terms of macroeconomics, it merely involves four aspects: design schemes, raw materials, manufacturing and installation, as well as application and maintenance. Therefore, in order to ensure the safety of glass curtain walls, they must undergo regular safety performance appraisals
