随着科学技术的不断发展,能量的消耗越来越大。从总体上看,建筑能量的消耗占总能耗的40～80%,而通过外墙损失的能量约占建筑总能耗的35～40%。本文所介绍的“纤维增强聚苯乙烯复合外墙保温板”是北京市建筑设计院和冶金部建筑研究总院共同开发研制的,已于1988年通过技术鉴定。这种复合外墙保温板是由主墙、保温层、纤维 With the continuous development of science and technology, the consumption of energy is increasing. On the whole, building energy consumption accounts for 40 to 80% of the total energy consumption, while the energy lost through the external wall accounts for about 35 to 40% of the total building energy consumption. The “fiber-reinforced polystyrene composite external wall insulation board” introduced by this article was jointly developed by the Beijing Architectural Design Institute and the Ministry of Metallurgical Construction Research Institute. It passed the technical appraisal in 1988. This composite external wall insulation board consists of main wall, insulation layer, fiber
