卷材防水屋面是一种比较简单的平屋顶构造。从其设计构造来看,一般由结构层、隔热层、隔气层、找平层、防水层等组成,它除了结构承重以外,还具有隔气、防潮、保温、防水等多种功能,同时它还具有减少空间高度、节约木材、提高建筑耐火等级、造价比较经济等优点,所以到目前为止仍然广泛地应用于工业和民用建筑中。多年来,在设计、材料质量和施工操作等方面,还存在着一些问题。很多工程建成后经不起时间 Roll waterproof roof is a relatively simple flat roof structure. From the point of view of its design and construction, it is generally composed of a structural layer, a heat insulation layer, a gas barrier layer, a screed layer, a waterproof layer, etc. In addition to the structural load-bearing structure, it also has a variety of functions such as gas barrier, moisture-proof, thermal insulation, and waterproof. It also has the advantages of reducing the height of space, saving wood, improving the fire resistance rating of buildings, and making the construction cost more economical, so it is still widely used in industrial and civil buildings. Over the years, there have been some problems in design, material quality, and construction operations. Many projects can’t afford time after they are completed
