Furthermore, in such systems, the curtain wall structure is constantly exposed to the elements, making it susceptible to rainwater leakage due to variations in temperature, humidity, and wind. The steel frame is also vulnerable to moisture erosion, creating safety hazards. Therefore, high precision in construction and effective waterproofing are essential. Summary of the Invention
