种植屋面从下往上分为多层,一是屋面结构层,由强度等级不低于C20的现浇钢筋混凝土构成;二是找坡层,用一定强度的轻质材料、陶粒、加气混凝土等构成,坡度1﹪～3﹪;三是保温层,用一定强度和导热系数小、吸水率低的材料构成,如XPS挤出聚苯乙烯泡沫保温板,硬泡聚氨酯保温材料等,还可以用泡沫玻璃等,最多 Planting roof is divided into several layers from the bottom up, one roof structure layer, by the strength level of not less than C20 cast-in-situ reinforced concrete composition; the second is to find slope, with a certain strength of light materials, ceramsite, Concrete, etc., the slope of 1% to 3%; Third, the insulation layer, with a certain strength and thermal conductivity of small, low water absorption materials, such as XPS extruded polystyrene foam insulation board, foam polyurethane insulation materials, etc. Can use foam glass, etc., up to
