Research on Quality Control and Supervision System for External Thermal Insulation of Building Facades

建筑外墙外保温具有保护墙体结构、延长建筑使用寿命、消除建筑“热桥”现象、节约建筑室内空间等优点。然而，当前建筑外墙外保温却常出现裂缝、破损、渗漏、保温层脱落、饰面砖脱落等病害，不仅影响城市建筑外立面的美观及建筑的使用功能，还可能产生巨大的安全隐患。因此，建立建筑外墙外保温质量控制与监管体系是优化工程质量，保障建筑安全与耐久性，降低事故风险，提升建筑节能效率，推动绿色建筑发展及降低全生命周期成本的有效路径，具有多维度的重要价值。The external thermal insulation of building walls has advantages such as protecting the wall structure, extending the building’s service life, eliminating thermal bridging phenomena, and saving indoor space. However, current practices frequently encounter defects such as cracks, damage, water leakage, insulation layer detachment, and decorative tile shedding. These issues not only compromise the aesthetic appeal of urban building facades and functional performance, but may also pose substantial safety hazards. Therefore, establishing a comprehensive quality control and supervision system for external thermal insulation is crucial for improving project quality, ensuring building safety and durability, reducing accident risks, enhancing energy efficiency, promoting green building development, and lowering lifecycle costs. This study carries multidimensional significance.
