4 kinds of rock w001.Through the analysis of the physical and mechanical properties,we obtained the rock wool 7S perfor- mance change rule with the change of the external conditions.The conclusion shows that the various performance indicators of rock wool are all in line with ENl3500,ENl3162 and ETAG004 s requirements.So this paper puts forward the notes when the rock wool is used in the exterior insulation system.What'
S more,it also provides some certain theoretical basis for the engineering prac- tice. Key words:exterior insulation;

performance 岩棉作为一种经济、高效、耐火、实用的保温材料,已经 被广泛应用于保温板材制作【11.相对于EPS板、XPS板、喷涂 硬泡聚氨酯等保温材料,岩棉作为A级防火材料不但满足了 国家建筑节能的要求,同时也很好地解决了保温材料防火性 能差、施工困难、造价高等问题.在我国,岩棉作为防火材料 用于外墙外保温系统虽已有应用,但尚未普及,其应用技术 仍在探讨中.而在欧洲已经有几十年的发展历史,拥有成熟 的产品标准和系统认证指南.岩棉应用于外墙外保温,其形 式可以是墙体总体使用岩棉保温(使用岩棉板,纤维平行于 墙面),同时具有外墙防火的作用;
也可以配合其它保温材料 使用,其中岩棉带起防火隔离的作用(称隔离带,纤维垂直于 基金项目:北京市建筑科技项目(K200901
