摘　　要：通过对不同保温构造的金属屋面进行隔热性能分析,得出:1)玻璃棉和岩棉的隔热性能基本相近;2)采用高明度的反射隔热涂料,能在满足屋面隔热性能要求的前提下降低保温层需要的厚度;3)随着保温棉厚度的增大,隔热性能会进一步提高,但是两者不是简单的线性关系,不能完全依赖增加保温棉的厚度来提高屋面的隔热性能。By analyzing heat insulating performance of metal roofs with various thermal insulating structure,some points may come out:1)Insulating performance of both glass wool and rock wool are more or less the same;2)If highly transparent reflective insulating coating can be up to heat insulating requirement then thermal insulating thickness can be reduced;3)As thickness of insulating wool is increased,the insulating performance would be increased as well,but these two are not connected linearly.Simply increase the thickness of insulating wool for higher insulating performance is not feasible.
