本文介绍了国外外墙外保温系统防火的主要要求,对比分析了我国规范的不足与差异。在此基础上,提出保温材料的燃烧性能不是评价外保温系统防火性能的唯一指标,应从材料的燃烧性能和系统的防火性能两方面提出要求,全面评价外墙外保温系统的火灾风险和隐患。对于外墙外保温系统的防火问题,应秉承科学、严谨的态度合理解决,建立开放性的、性能化的外墙外保温防火技术标准要求。 This paper introduces the main requirements for fire prevention of exterior wall insulation system abroad and compares and analyzes the shortcomings and differences of our country’s standard. On this basis, it is proposed that the combustion performance of the insulation material is not the only index to evaluate the fire performance of the insulation system. The requirements of both the combustion performance of the material and the fire performance of the system should be put forward to fully evaluate the fire risks and hidden dangers of the exterior insulation and insulation system. For the external insulation system fire safety issues, should uphold a scientific and rigorous approach to a reasonable solution to establish an open, performance-based exterior insulation fire safety standards.
