加强建筑围护结构保温是节约建筑采暖能耗的基础。实践证明,为使外墙保温性能有较大的改善,必须要使墙体复合化。由于复合墙体能满足围护结构多种功能要求,因此有进一步发展的趋势。1986年初,北京市建筑设计院和冶金部建筑研究总院合作,对以高效保温材料聚苯板为外保温层的复合外墙进行了复合技术与工程应用试验研究。
Strengthening thermal insulation of building envelopes is the basis for saving building heating energy. Practice has proved that in order to greatly improve the insulation performance of the external wall, the wall must be composited. Because the composite wall can meet the various functional requirements of the envelope structure, it has a further development trend. At the beginning of 1986, Beijing Architectural Design Institute and the Ministry of Metallurgical Construction Research Institute cooperated to carry out the composite technology and engineering application research on composite external walls with high thermal insulation material polystyrene board as the external thermal insulation layer.
