        外墙外保温是一项先进的外墙节能技术。但外保温系统位于建筑物的外表面，直接面向大气环境。除系统性能应承受室外多种不利因素的作用和满足外墙的保温隔热要求外，其可靠性、完全性和耐久性尤为重要。
　　在高层建筑中使用，需要特别注意下列问题：
　　一、是系统与基层墙体应有可靠的固定。高层建筑应承受风荷载较大，而且墙体部分会产生很大负风压吸力。因此，保温层应与基层无机材料有可靠的黏结，尤其是采用有机材料，一定要注意这个环节。而由无机材料构成的保温层，如伊通建筑保温系统，与各种基层墙体无机的混凝土、各类墙体材料等具有良好的性和相容性;同时受到风荷载作用下不会变形、剥落，具有高度的安全性和可靠性。
　　二、是系统的防火性能应符合国家有关法律规定。现在用于高层建筑的外保温较多采用阻燃性聚苯板，这类材料具有可燃性，用于高层建筑外墙应采取防火构造措施，如设置防火隔离带等。相对这类有机，伊通保温系统具有极好的防火性和燃烧性，不会产生有毒气体。根据国家有关机构检测：伊通保温块耐火极限可达两个小时以上。
　　三、是外饰面层应采用或彩色砂浆。系统中的保温层多为轻质多孔材料、剪力强度较低，所以饰面层不宜采用面砖。如黏贴面砖必须要有可靠的措施，以防止面砖脱落伤人。而伊通保温系统表面有保护层进行加固，具有高强度和优良的抗冲击性能。
　　四、是系统的耐久性能应满足要求。在正常使用和维护条件下，外墙外保温工程的使用年限应不少于25 年。伊通保温系统主材均为无机硅酸盐材料，具有优良的抗老化性，寿命和混凝土无机材料相当，是其他保温材料所不能比拟的。
 

     The outer walls of the external wall thermal insulation is an advanced energy saving technology. But in the outer surface of the building external thermal insulation system, directly to the atmospheric environment. In addition to the performance of the system should be outside under the effect of various unfavorable factors and can satisfy the demands of exterior wall thermal insulation, its reliability, completeness and durability is particularly important.
    Used in high-rise buildings, we need to pay special attention to the following questions:
A, is a system with reliable fixed wall should be at the grass-roots level. High-rise buildings should be under wind load is bigger, and the wall part will produce a lot of negative pressure suction. As a result, the thermal insulation layer should be reliable cohere with the basic inorganic materials, organic materials, in particular, it is important to note that this link. Composed of inorganic material thermal insulation layer, such as YiTong building insulation system, with a variety of primary wall, all kinds of inorganic concrete wall materials has good suitability and compatibility; At the same time under wind load will not deformation, peeling, high safety and reliability.西宁保温材料|西宁防水材料|青海保温防水材料|西宁硅酸盐|青海硅酸盐
    Second, is the fire performance of the system shall comply with the relevant state laws and regulations. Now used in high-rise building external thermal insulation is more use of flame retardant polystyrene board, this kind of material is flammable, used for high-rise building exterior wall fire protection construction measures should be taken, such as setting fire belt. Relative to this kind of organic, YiTong thermal insulation system has excellent fire retardancy and combustibility, won't produce poisonous gas. According to relevant state institutions detection: YiTong insulation piece of fire resistance can be more than two hours.西宁保温材料|西宁防水材料|青海保温防水材料|西宁硅酸盐|青海硅酸盐
    Three, the outer layer or color mortar shall be used. System in the thermal insulation layer for lightweight porous materials, the shear strength is low, so you should not use brick act the role of the surface. Such as paste tile must have reliable measures, in order to prevent the tile off cuts. To fortify and YiTong protective layer at the surface of the insulation system, with high strength and good impact resistance.西宁保温材料|西宁防水材料|青海保温防水材料|西宁硅酸盐|青海硅酸盐
    Fourth, is the durable performance of the system should meet the requirements. Under the condition of normal use and maintenance, the use fixed number of year of external wall thermal insulation engineering should be not less than 25 years. Main materials are inorganic silicate materials YiTong insulation system, with excellent aging resistance, longevity and concrete inorganic material, is can't be matched by other insulation material.
