一个建筑物的墙系统必须不断打的雨，空气，蒸汽和热attacks.The壁的，以提供一个屏障，这些元件的每能力入侵依赖于使用相应的材料，安装在正确的序列。 There is no such thing as a perfect wall system; however, a wall system that performs with greater efficiency using new efficient materials is achievable.
Rigid fiber or fibrous board insulation consists of either fiberglass or mineral wool and is primarily used for insulating air ducts in homes. It is also used when there's a need for insulation that can withstand high temperatures.
Reflective insulation systems are fabricated from aluminum foils with a variety of backings, such as kraft paper, plastic film, polyethylene bubbles, or cardboard. The resistance to heat flow depends on the heat flow direction. Reflective insulation is most effective at reducing downward heat flow.
Foam boards—rigid panels of insulation—can be used to insulate almost any part of your home, from the roof down to the foundation. They provide good thermal resistance and often add structural strength to your home. Foam board insulation sheathing reduces heat conduction through structural elements, like wood and steel studs.
<强>的聚氨酯 是用于含有低传导性气体闭孔泡沫绝缘材料（通常氢氯氟烃或在其细胞中HCFC）。的气体的高耐热性赋予聚氨酯保温材料的R值一般为约R-7〜R-8每英寸。
Polyisocyanurate or polyiso is a thermosetting type of plastic, closed-cell foam that contains a low-conductivity gas (usually hydrochlorofluorocarbons or HCFC) in its cells. The high thermal resistance of the gas gives polyisocyanurate insulation materials an R-value typically from R-5.6 to R-8 per inch.
<强>的聚苯乙烯 - 无色透明的热塑性塑料 - 常用于化妆泡沫板或beadboard绝缘，混凝土块绝缘和一个键入松散填充绝缘的，它由聚苯乙烯小珠。
<强>板绝缘下，也被称为泡沫塑料板绝缘，可以在建筑施工中，以提供耐热性的许多领域中使用。是适当的下混凝土楼板使用，在基础墙壁，在壁的空腔，作为用于与新壁板重塑背衬材料，并且在宽范围屋面应用的。泡沫塑料板包括三种类型：的聚苯乙烯下，的聚异氰脲下，和聚氨酯即可。所有类型的泡沫塑料板的隔热板的需要保护来自太阳的紫外线损伤的效果。另外，泡沫塑料绝缘应当从火被保护，因为它会发出含有有毒气体浓烟。建筑用饰面的泡沫塑料绝缘板由码需要在耐火材料被完全掩盖。玻璃纤维树脂混合物和矿棉在板产品还制造用于建筑应用中使用。毯，发泡就地，疏松填料，吹入喷型绝缘总结于其它部分。
