建筑外墙外保温技术应用的研究

摘要

In the structure of the building envelope, wall proportion is the largest. In winter the quantity of heat loss through the wall is about 20％of the total heat loss and in summer the quantity of heat absorbed through the outer wall is about 30％ of the total absorbed heat, so thermal insulation design of outside wall is very important. This paper made simple exposition on the history of building exterior insulation technology, the classification of building exterior insulation, technical analysis of building exterior insulation and development trend.%在建筑外围护结构中,墙体所占比重最大,冬季通过墙体散失的热量,约为建筑总散热量的20%,夏季通过外墙体吸收的热量,约为建筑总吸热的30%,因而外墙体的保温设计相当重要.本文就建筑外墙外保温技术的历史;建筑外墙外保温的分类;建筑外墙外保温的技术分析和发展趋势做了简单的论述.
