甘肃省居住建筑岩棉外墙外保温耐久性试验研究

Durability of rock-wool exterior wall insulation for residential building in gansu province

为进一步研究居住建筑外墙外保温用岩棉板的耐久性与耐候性,对已建成使用20年的两栋岩棉外保温住宅楼进行了研究,通过考察其结构、外墙饰面缺陷、传热系数、保温性能等方面,分析切实影响外墙保温性能的因素,表明岩棉外保温系统的保温隔热、耐久性能等都较好,为相关研究提供了一定参考。

In order to further study the durability and weatherability of rockwool panels used for thermal insulation of exterior wall of residential buildings, two rockwool exterior thermal insulation residential buildings that have been completed and used for 20 years have been studied. By examining their structure, defects of exterior wall finishes, Heat transfer coefficient and thermal insulation performance, the factors that affect the thermal insulation performance of the exterior wall are analyzed. The results show that thermal insulation and durability of the thermal insulation system of rock wool are good, which provides a reference for related research.
