一、外墙外保温体系的组成
      所谓外墙外保温，是指在垂直外墙的外表面上建造保温层，该外墙用砖石或混凝土建造，此种外保温，可用于新建墙体，也可以用于既有建筑外墙的改造。该保层对于外墙的保温效能增加明显，其热阻值超过1 m2 ·K/W。由于是从外侧保温，其构造必需能满足水密性、抗风压以及温湿度变化的要求，不致产生裂缝，并能抵抗外界可能产生的碰撞作用，还能与相邻部位（如门窗洞口、管道等）之间以及在边角处、面层装饰等方面，得到适当的处理。然而，必须注意，外保温层的功能，仅限于增加外墙保温效能以及由此带来的相关要求，而不应指望这层保温构造对主体墙的稳定性起到作用。其主体墙，即外保温层的基底，必须满足建筑物的力学稳定性的要求，能承受垂直荷载、风荷载，并能经受撞击而何证安全使用，还应能使被覆的保温层和装修层得以牢牢固定。
   1．保温层：应采用热阻值高,即导热系数小的高效保温材料，其导热系数一般小于0.05W/m·K.根据设计计算，具有一定厚度，以满足节能标准对该地区墙体的保温要求。此外，保温材料的吸湿率要低，而粘结性能要好;为了使所用的粘结剂及其表面的应力尽可能减少，对于保温材料，一方面要用收缩率小的材料，另一方面,尺寸变动时产生的应力要小。为此，可采用的保温材料有:膨胀型聚苯乙烯（EPS）板、挤塑型聚笨乙烯（XPS）板、岩棉板、玻璃棉毡以及超轻保温浆料等。其中以阻燃膨胀型聚苯烯板应用得较为普遍。
   2．保温板的固定：不同的外保温体系,采用的固定保温板的方法各有不同。有的是将保温板粘结或锚固在基底上，有的为两者结合，以粘结主为，或以锚固为主。将保温板粘结在基底上的粘结材料多种多样。在不同的体系中，此种粘结材料运到工地时的状态有所不同：
    A, the composition of exterior insulation system
    In the external wall thermal insulation, refers to the vertical wall insulation layer, the outer surface of building the walls are built of brick or concrete, this kind of external thermal insulation, can be used for the newly built wall, can also be used for both the improvement of exterior walls. The cover layer for exterior wall insulation efficiency significantly increased, the thermal resistance than 1 m2, K/W. Because from the outside heat preservation, the structure can meet the necessary water tightness, wind resistance and the change of temperature and humidity requirements, not cracks, and can resist the possible collision, also with the adjacent parts (such as Windows and doors hole, wall pipe, etc.) and in the corners, surface decoration, etc., properly handle. , however, must pay attention to, the function of external thermal insulation layer, only of exterior wall thermal insulation performance and the resulting increase in the relevant requirements, and should not count on this layer insulation structure play a role to the stability of the body wall. Outside the main wall, the thermal insulation layer of the basal, must meet the requirements of building the mechanical stability, able to withstand vertical load, wind load, and can withstand the impact and how safe use, should also can make the coating of insulation and decoration layer was firmly fixed.西宁保温材料|西宁胶粉|青海保温材料|青海胶粉
     1. The insulation: high thermal resistance should be adopted, namely small coefficient of thermal conductivity of high efficiency heat preservation material, its thermal conductivity is generally less than 0.05 W/m. k. according to the design and calculation, with a certain thickness, in order to meet the requirements for the region's wall insulation energy-saving standards. In addition, the heat preservation material to low moisture absorption rate, the bond performance is better; In order to make the stress on the surface of the binder and its reducing as far as possible, for thermal insulation material, on the one hand with a little shrinkage of the material, on the other hand, the smaller size changes during stress. Can be used for this purpose, the thermal insulation material has: inflating polystyrene board (EPS) and extruded type poly ethylene (XPS) stupid board, rock wool board, glass cotton blanket and lightweight insulation slurry, etc. With flame retardant inflating polypropylene plate are more widely used.西宁保温材料|西宁胶粉|青海保温材料|青海胶粉
      2. Insulation board is fixed: different external thermal insulation system, adopt the method of fixed insulation board is different. Have a plenty of the heat preservation plate bonding or anchorage in the basement, some for the combination of these two, for binding main, or is given priority to with anchorage. The insulation board in cement base material is varied. In different system, this kind of adhesive materials to the site condition is different西宁保温材料|西宁胶粉|青海保温材料|青海胶粉
