屋面节能是建筑节能重要的组成部分,对保温材料的要求比较严格,首先要憎水、质轻、导热系数小。传统上采用炉渣、珍珠岩、蛭石类保温材料,容重大,导热系数高,吸水,特别是吸水后导热系数升高,要做到防水保温,从结构上来讲必将带来不少麻烦。国内近年来有 Roof energy-saving is an important part of building energy-saving. The requirements for insulation materials are more stringent. The first thing is to dredge water, light weight and small thermal conductivity. Traditionally, slag, perlite, and vermiculite thermal insulation materials are used, which have large capacitance, high thermal conductivity, and high water absorption. In particular, the thermal conductivity after water absorption rises. To achieve waterproof and thermal insulation, it is bound to cause many problems in terms of structure. In recent years, there are
