    一.墙外保温系统的起源。
   外墙外保温系统起源于上世纪四十年代的瑞典和德国，至今已有60多年的历史，经过多年的实际应用和全球不同气候条件下长时间的考验，证明采用该类保温系统的建筑，无论是从建筑物外装饰效果还是居住的舒适程度，都是一项值得全球范围内推广应用的节能新技术。如今，外墙外保温建筑已经成为欧美等发达国家市场占有率最高的一种建筑节能技术。
    20世纪60年代，美国从欧洲引进此项技术，并根据本国的具体气候条件和建筑体系特点进行了改进和发展。同样在70年代初的能源危机期间，由于建筑节能的要求，外墙外保温及装饰系统在美国的应用不断增加，至90年代末，其平均年增长率达到了20～25％。至今此项技术在美国的应用也达40多年之久，最高建筑达44层，并在美国南部的炎热地区和寒冷的北部地区均有广泛的应用，效果显著。
    美国和欧洲在40余年的应用历史中，对外墙外保温系统进行了大量的基础研究，如薄抹灰外墙外保温系统的耐久性的问题；在寒冷地区中的问题；同类型的系统在不同冲击荷载下的反应；试验室的测试结果与实际工程中性能的相关性等。在大量的实验研究的基础上，目前美国和欧洲对外墙外保温已有严格的立法工作，其中包括要求外墙外保温系统的强制性认证标准，以及对于系统中相关组成材料的标准等。由于欧美国家有着相应健全的标准、严格的立法，对于外墙外保温系统的耐久性一般都可以要求25年的使用年限。事实上，该系统在上述地区的应用历史已大大超过25年，这都是值得我们借鉴学习的。
     A. The origin of the external wall thermal insulation system.
Exterior insulation system originated in Sweden and Germany in the 1940 s, has been more than 60 years of history, after many years of practical application and the different climate conditions for a long time test, shows that the application of the insulation system architecture, both from the outside the building adornment effect and degree of comfortable living, is a worthy of popularization and application of the global energy saving new technology. Nowadays, exterior insulation construction has become the European and American developed countries such as the highest market share of building energy efficiency technology.西宁保温材料|西宁胶粉|青海保温材料|青海胶粉
    Introducing the technology from Europe in the 1960 s, the United States, and according to its own specific conditions and characteristics of building system is improved and developed. Also during the energy crisis in the early 70 s, due to the requirement of building energy efficiency, exterior insulation and decoration system applied in the United States continues to increase, to the late 90 s, the average annual growth rate has reached 20 ~ 25%. So far in the United States the application of the technology for more than 40 years, the highest building of 44 layer, and the hot areas in the southern states, and northern cold region are widely used, the effect is remarkable.
    The United States and Europe in the application of more than 40 years of history, the external wall external thermal insulation system for a large amount of basic research, such as thin plastering exterior insulation system of the durability of the problem; Dew point in the cold region; The same sort of system response under different impact load; Laboratory test results and the relevance of performance in practical engineering. On the basis of a large number of experimental studies, the American and European external wall external thermal insulation has strict legislative work, including exterior insulation system of compulsory certification standards, and the system of relevant material standards, etc. As Europe and the United States has a corresponding sound standards, strict legislation, for the durability of exterior insulation system generally can request the service life of 25 years. In fact, the history of the application of the system in the region has more than 25 years, it is worth our using for reference of learning.西宁保温材料|西宁胶粉|青海保温材料|青海胶粉
