Prior to 1980, the development of insulation materials in China is very slow, external wall insulation board one of the few insulation material factory to produce only a small amount of expanded perlite, expanded vermiculite, slag wool, ultra-fine glass wool, porous calcium silicate and other products, slag wool plant little less than million tons of production capacity, bulk cotton, calcium silicate insulation materials, only three annual output of 8000 cubic meters.

1980年以前，我国保温材料的发展十分缓慢，外墙保温一体板为数不多的保温材料厂只能生产少量的膨胀珍珠岩、膨胀蛭石、矿渣棉、超细玻璃棉、微孔硅酸钙等产品，矿棉厂很少，生产能力不足万吨，散棉、硅酸钙绝热材料也只有3家，年产8000立方米。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
