由大庆油田设计院研究完成的“保温复合外墙节能型住宅楼”研究项目选用塑料袋装散粒膨胀珍珠岩和憎水膨胀珍珠岩作墙身和屋面的保温材料。经黑龙江省寒地建筑科学研究院测试结果认为：该节能型保温复合外墙及屋面住宅楼房墙体的西墙和北墙，外墙传热系数Kw=0．41－0．57W／m2 The “Energy-saving composite external wall energy-saving residential building” research project completed by the Daqing Oilfield Design Institute selected plastic bagged bulk expanded perlite and hydrophobic expanded perlite for the wall and roof insulation. According to the test results of the Heilongjiang Provincial Institute of Building Research, the heat transfer coefficient of the wall of the wall of the energy-saving insulation composite exterior wall and roofing residential building is Kw=0.41-0.57 W/m2.
