However, at present, the building energy saving level of China is far behind developed countries. The development and progress of the construction of external wall insulation technology is focused on the development of energy saving in china. However, if you want to improve the performance of the wall insulation, fire prevention, reasonable design of the wall thermal insulation system; safety, quality of wall thermal insulation material is the key. Building exterior wall thermal insulation system can be divided into the following three categories: system, external wall insulation system and external wall insulation system of external wall thermal insulation.外墙自保温体系指的是以单一墙体材料即能满足现有节能及保温要求的外墙保温体系。外墙自保温体系是将墙体承重与墙体保温相结合的墙体保温技术，常用保温复合墙板、加气混凝土砌块等墙体构件达到墙体保温目的。在南北方都开始大量应用，虽然尚未形成很高的市场占有率，但发展前景十分可观。External wall insulation system refers to the single wall material can meet the requirements of the existing energy-saving and exterior wall insulation system. External wall insulation system is the load-bearing wall and wall thermal insulation combined wall insulation technology, commonly used thermal insulation composite wall, aerated concrete block wall component reaches the wall insulation purpose. In the South and the north are widely, although has not yet formed a very high market share, but the prospect is very considerable.墙体自保温体系多数情况采用复合墙板或砌块构件建造，表面以无机材料主，即使是夹心砌块，可燃的保温材料也被包裹在里面，因此大大降低了使用和施工期间发生火灾的几率。Wall insulation system in most cases using composite wallboard or block structural, surface to inorganic material, even the sandwich block, heat preservation material combustible is wrapped inside, so the probability of fire occurrence during the use and construction of the greatly reduced.保温材料在构件芯部受到外层材料的保护不容易老化，因此墙体自保温体系，解除建筑物全生命周期内多次维修更换保温层及外墙装修的麻烦，远期经济效益好。且该体系不存在墙身主体材料与保温材料的连接问题，从而避免建筑保温层大面积脱落事故发生。Thermal insulation material in the core protected members of outer material is not easy to aging, so the wall insulation system, lift the whole life cycle building multiple repair replacement of insulation and exterior wall decoration of trouble, long-term economic benefits. And the system does not have connection problems wall body material and thermal insulation material, so as to avoid falling accidents of large area building insulation layer.构件在构件厂生产，产品生产责任明确，生产环境相对较好，质量管理容易到位，生产人员受人为不良因素影响小，产品质量容易也控制。在施工过程中工艺符合传统的施工工艺，操作人员技术成熟施工质量也容易控制。Component in the component factory production, product responsibility, the production environment is relatively good, quality management is easy to reach the designated position, production personnel to be affected by human factors in small, easy to control product quality. During the construction process in accordance with the traditional construction technology, mature technology and construction quality control personnel also easy operation.由于外墙自保温体系中的墙体承重构件与保温材料合为一体，因此根本不存在保温层大面积脱落的问题。我国地域辽阔，气候差异大，南方北方室内外温差不同，这就要求南方和北方地区的外墙保温隔热可以采用不同的体系。由于我国巨大的建设规模和建筑现代化的快速发展，按照大规模推广应用的外墙外保温技术发展现状，一种单一的技术形式已无法满足市场需求，根据多年经验，北方采暖地区只有采取外墙自保温墙体或者外墙外保温与自保温二者结合的保温体系才能满足这些基本要求，在南方地区采用外墙外保温、外墙内保温或者自保温墙体都可以满足这些基本要求。因地而异采用不同的外墙保温技术，应符合建筑节能标准及人们居住舒适性要求。在北方采暖地区采用自保温墙体技术和局部热桥部位采用外保温技术相结合的方式，完全可以满足节能 50%甚至 65%标准要求。由此不难看出，自保温墙体技术和复合保温墙体技术同步发展，不仅在技术上可行，经济上有益，标准上无障碍，市场上有需求，在实现建筑节能的同时大大促进建材行业技术进步，一举多得，既符合国家相关政策又符合市场发展规律。Because the load-bearing member self thermal insulation system of exterior wall with thermal insulation material as a whole, there is thus no extensive loss insulation layer problem. Chinas vast territory, large differences between the north and the south climate, indoor and outdoor temperature difference, this requires that the north and the south area of the external wall insulation can adopt different system. Due to the rapid development of the construction scale and the building of modern huge in China, according to the large-scale application of external wall insulation technology development status, a single technology has been unable to meet market demand, based on years of experience, northern heating areas only take wall self-insulation wall or external thermal insulation and thermal insulation of the combination of the two insulation system in order to meet these requirements, in the southern region of the external wall insulation, exterior wall insulation and wall insulation can meet the basic requirements. Vary with different external wall thermal insulation technology, shall be in accordance with building energy efficiency standards and people living comfort requirements. The wall insulation technology and local thermal bridge part of the external insulation technology combination in northern heating areas, can fully meet the energy-saving 50% or even 65% standard requirements. It is not difficult to see, since the insulation wall and composite wall insulation technology synchronous development, not only technically feasible, economically beneficial, standard accessibility, market demand, the implementation of building energy efficiency and greatly promote the building materials industry technology progress, too, is consistent with the relevant national policies and the laws of market development.综上所述外墙保温系统设计方案的选择，不仅要考虑保温、节能效果。更重要的还要考虑建筑在施工过程中和建成后使用时的防火、安全问题，及长远的经济效益。由于建筑外墙的自保温体系具有上述优点，因此该体系更加适合我们国家的建筑保温技术发展状况，它将是今后节能墙体改革发展的重要方向，对于降低能源消耗、减少环境污染、促进节能减排、实现可持续发展都具有重要的意义。To sum up the external wall insulation system design scheme, not only to consi
