摘　　要：建筑外墙外保温系统的防火要遵循安全性、整体性和重要性的原则;防火的总体思路是在现有建筑防火规范的基础上,根据建筑的类别确定建筑的耐火等级,考虑可燃性、燃烧热、发烟量和烟气毒性等因素对保温材料和外墙外保温系统的燃烧性能分级,再根据建筑的耐火等级选择相应燃烧性能等级的保温材料和外墙外保温系统,并确定相应的防火技术措施。Fire protection in building external thermal insulation systems must be paid more attention and should follow the guidelines of security, integrity and importance. The general idea of fire protection in building external thermal insulation systems is that on the basis of current code of building fire protection, we decide the fire resistance rating of building according to its sort, and also classify the grade of the external thermal insulation system or materials based on the flammability, heat of combustion, smoke release and smoke toxicity. Then the external thermal insulation materials or systems and technology measures for fire protection were selected by fire resistance rating of building.
