What are the exterior wall thermal insulation materials?
Metal insulation material:Mainly aluminum and its products, such as aluminum plate, aluminum foil, aluminum foil, composite light plate, etc.. It uses the radiation characteristics of the material surface to obtain the heat insulation performance.Advantages and disadvantages: with this kind of surface characteristics of the material, almost do not absorb the heat on it, and the ability to radiate heat itself is also very small, this kind of material supply less, more expensive.
Inorganic insulation material:A mineral mineral wool, perlite, vermiculite, diatomite, gypsum, slag, glass fiber, wool, aerated concrete, foam concrete, pumice concrete and its products, chemical synthesis of polyester and synthetic rubber with polystyrene, PVC, polyurethane, polyethylene, urea formaldehyde plastics and foam rigid ester and its products etc..Advantages: this kind of material does not decay, high temperature resistance, partial moisture absorption, easy to burn, more expensive.
Organic thermal insulation material:Such as rice straw, rice husk, sugarcane fiber, softwood, kapok, sawdust, wood shavings, wood fiber and their products.Advantages: this kind of material has a small volume, a wide range of sources, most of the low price, but the moisture absorption is large, easy to decay after damp, and easy to decompose or burn at high temperature.
