外墙外保温作为一种有效的节能材料,其节能效果已经得到了专家的认可,近年来在我国随着国家对民用建筑节能标准的强制执行,这类新型材料在建筑界得到了迅速的推广及应用。这种新型的保温材料在使用过程中也曝露出一些质量问题,例如,应用外墙保温的节能住宅中出现了饰面层脱落、空鼓、开裂、室内返霜、结露等质量问题。造成这些问题的因素很多。
External insulation as an effective energy-saving materials, the energy-saving effect has been recognized by experts in recent years in our country with the national civil building energy efficiency standards for the implementation of these new materials in the construction industry has been rapidly promoted And application. The new type of thermal insulation material also shows some quality problems during its use. For example, quality problems such as decorating, hollowing out, cracking, interior frosting, dew condensation and the like appear in the energy-conserving house with exterior wall thermal insulation. There are many factors that cause these problems.
