夏热冬冷地区建筑外墙保温材料和保温形式的发展趋势

The Development Trend of Exterior Wall Thermal Insulation Material and Thermal Insulation Form in Hot Summer and Cold Winter Zone

夏热冬冷地区围护结构设计需要同时考虑冬季保温与夏季隔热的问题,这对建筑的围护结构节能设计提出了较高的要求。在介绍常用的外墙保温材料性能和保温形式基础上,针对夏热冬冷地区的气候特征和建筑特点,进行外墙保温材料和保温形式的研究,指出在保温材料方面,复合保温材料结合了有机保温材料和无机保温材料各自的优点,在一定程度上解决了无机保温材料厚度较大而有机保温材料防火性能差的不足;在保温形式方面,建筑外墙内外组合保温和墙体自保温体系相结合是夏热冬冷地区保温形式的发展趋势,这种保温形式的实质就是保温材料与砌体相结合,共同实现建筑外围护综合保温的目的。

In hot summer and cold winter zone, retaining structure design should be considered thermal insulation in winter and heat insulation in summer together, so it has a higher design requirement of energy-saving. On the basis of introducing the performance of thermal insulation material and thermal insulation form commonly used for external wall, external wall insulation materials and insulation form were studied and their development trend was discussed according to the climate characteristics and the building features in hot summer and cold winter zone. Organic insulation materials are not good at fireproof performance, and inorganic insulation materials usually have large thickness. Composite insulation materials combine the respective advantages of both and to some extent, it tackles their deficiencies. According to thermal insulation form, development trend is to combine the two is mixing the interna and external insulation of exterior wall; another is self-insulation system of exterior wall. The essence of this thermal insulation form is the combination of thermal insulation material and brickwork, so it can realize the aim of integrated insulation for building envelope.
