For the building that has been completed, the building wall hole is one of the relatively weak parts of the safety performance of building structure, and the safety vulnerability of building window mainly reflects in material safety, design and installation problems, insufficient maintenance and management, and weak ability to resist external threats. The safety performance of building hole is limited, and there is no standardized secondary safety upgrade performance. Especially for banks or other buildings that need to strengthen public safety, although the windows of the building have excellent sealing performance and wind pressure resistance to resist strong winds and rain and other harsh weather. In addition, the material used for the window should have sufficient fire resistance to delay the further spread of fire in case of fire. If the fire resistance of the window is insufficient, it will seriously threaten the evacuation and fire extinguishing work of personnel.
