利用加气混凝土轻质保温的特点,在我国北方主要发展较低容重(500公斤/米~3)的加气混凝土板材,用作屋面板和非承重外墙等围护结构,获得了良好的技术经济效果。我国南方建筑一般自然通风良好,室内外温差不大,对围护结构的保温隔热性能要求不太高。外墙厚度主要取决于承载能力和构造要求。造成某些房间夏季闷热 By using the characteristics of lightweight insulation of aerated concrete, aerated concrete slabs with low bulk density (500kg/m~3) are developed in northern China and used as envelopes for roofing panels and non-load-bearing outer walls, which have achieved good results. Technical and economic effects. In southern China, buildings are generally well-ventilated, and the temperature difference between indoor and outdoor areas is not large, and the thermal insulation performance of enclosure structures is not too high. The thickness of the outer wall depends mainly on the carrying capacity and construction requirements. Causes some rooms to become hot during the summer
