A Study on the External Wall Insulation System Safety Accidents in a Residential Community in Nanjing, China

The external wall insulation system is a critical component for ensuring building energy efficiency and residential comfort. However, such systems typically involve multiple trades, diverse materials, and complex construction processes, placing high demands on material performance, design standards, construction quality, and post-completion maintenance. In 2024, two safety incidents related to external wall insulation systems occurred in Nanjing, China, exposing significant issues in material selection, structural design, construction techniques, and maintenance supervision. These incidents warrant broad attention and discussion within the industry. By analyzing and studying these cases, students can be trained to uphold the fundamental requirements of compliance in engineering quality and safety management. Moreover, it fosters a deep understanding of the principles of "safety first and quality as the foundation."
