    屋顶保温是为了降低寒冷地区和夏热冬冷地区住宅顶层房屋的供暖耗热量和改善顶层房屋冬季的热环境质量的一项围护措施;屋顶隔热是为了降低夏热冬暖和夏热冬冷地区住宅顶层房屋的自然室温从而减少其空调能耗的围护措施。由于两者针对的围护对象不同，所采取的构造形式应有区，屋顶外墙保温和隔热设计时应依据《民用建筑热工设计规范》(GB50176-93)、《民用建筑节能设计标准(采暖居住建筑部分)》(JGJ26-95)、《夏热冬冷地区居住建筑节能设计标准》(JGJ134-2001)、《夏热冬暖地区居住建筑节能设计标准》进行。
　　一、外保温屋面特点
　　这种屋面保温形式是把保温材料做在屋顶楼板的外侧，让屋面的楼板受到保温层的保护而不致受到过大的温度应力，整个屋顶的热工性能能够得到保证，能够有效避免屋顶构造层内部的冷凝和结冻。屋面可上入。构造做法:通常做法是在楼板上设置绝热材料，在绝热材料外侧设置防水层和保护层。外墙保温材料的厚度应通过热工计算符合所在建筑热工分区的节能设计标准。
      适用范围：适用于寒冷地区和夏热冬冷地区的新建和改造住宅的屋顶保温。节能效果:按照民用建筑节能标准和民用建筑热工设计规范的要求确定的屋顶隔热层，能够保证冬季屋顶内表面温度和室内采暖环境温度的差值小于℃。
　　二、倒置式屋面
　　特点：这种屋面保温形式是外保温屋面形式的一个倒置形式，它是把保温层做在防水层的上部，防水层做在保温层和楼板的界面上，保温层上部的保护层有良好的透水和透气性能。这种屋面构造仍属于屋面外保温和屋面外隔热形式，能有效地避免内部结露，也使防水层得到很好保护，屋面构造的耐久性得到提高，但对保温材料的拒水性能有较高的要求，保温材料选择时应以保温材料本身绝热性能受雨水浸泡影响最小为原则。国内可供用于倒置屋面做法的外墙保温材料主要有泡沫玻璃、挤塑型聚苯乙烯泡沫板、聚乙烯泡沫板等。
      适用范围：适用于寒冷地区和夏热冬冷地区的新建和改造住宅的屋顶保温
     Roof insulation is to reduce the cold region and in hot summer and cold winter area is the top floor heating heat consumption of the building and improving the quality of the top housing winter the thermal environment of a containment measures; Roof insulation is to reduce the hot summer and warm winter, hot summer and cold winter area is the top housing natural room temperature so as to reduce the energy consumption of air conditioning containment measures. Because both in the retaining object is different, the structure of the form should be taken, exterior wall thermal insulation and heat insulation roof design on the basis of the civil building thermal design code (GB50176-93), the civil building energy-saving design standard (part) heating residential building "(JGJ26-95), the hot summer and cold winter area residential building energy efficiency design standard" (JGJ134-2001), the hot summer and warm winter area residential building energy efficiency design standard ".
    A, external thermal insulation roofing characteristics西宁保温材料|西宁胶粉|青海保温材料|青海胶粉
    The roof insulation heat preservation form is to put the material in the outer edge of the roof slab, let roof floor of the protection of the thermal insulation layer and without excessive thermal stress, thermal performance of the entire roof can be guaranteed, can effectively avoid condensation and frozen inside the roof structural layer. On the roof can be into. The structural approach: it is usually set on the floor of the insulation, waterproof layer and protective layer on the outside of the insulation. The thickness of exterior wall thermal insulation material should be through thermal calculation in building energy-saving design standard of thermal partitions.
Scope of application: suitable for cold areas with hot summer and cold winter area of renovation and new residential roof insulation. Energy saving effect: in accordance with the civil building energy saving standards and civil building thermal design specification requirements determine the roof insulation layer, can ensure the surface temperature and indoor heating environment in the roof in winter temperature difference is less than ℃.西宁保温材料|西宁胶粉|青海保温材料|青海胶粉
    Second, the inversion type roof西宁保温材料|西宁胶粉|青海保温材料|青海胶粉
    Characteristics: this type of roofing heat preservation is an inverted form of external thermal insulation roof form, it is to put the do in the upper portion of the waterproof layer insulation layer, waterproof layer in the thermal insulation layer and floor on the interface of thermal insulation layer of the upper layer has good waterproof and breathable performance. The roof construction is still belongs to the external thermal insulation and roofing insulation roof form, can effectively avoid the internal condensation, also make the waterproof layer to get good protection, the durability of roof structure was improved, but the repellent properties of thermal insulation material have higher requirements, the thermal insulation material selection should be minimum adiabatic performance of thermal insulation material itself is affected by rain water for the principle. Available for domestic inverted roofing practice of exterior wall thermal insulation material mainly include foam glass, extruded polystyrene foam board, PE foam board etc.西宁保温材料|西宁胶粉|青海保温材料|青海胶粉
