Calcium silicate bonded with sodium silicate. Although it is popularly considered an asbestos substitute, early uses of calcium silicate for insulation still made use of asbestos fibers. It is used in passive fire protection and fireproofing as calcium silicate brick or in roof tiles. It is one of the most successful materials in fireproofing in Europe because of regulations and fire safety guidelines for commercial and residential building codes (see Calcium Silicate use in Europe). Where North Americans use spray fireproofing plasters, Europeans are more likely to use cladding made of calcium silicate. High-performance calcium-silicate boards retain their excellent dimensional stability even
Building insulation temperature standard in China, most old residential and commercial buildings in China doesn’t have any thermal insulation, even in the area that suffer a severe weather which is hot in summer and cold in winter. And the insulation material that often used in the new buildings of China is Styrofoam, which has difficulties in installation and low effectiveness of thermal insulation. Another problem is that the Styrofoam is not fireproof material, it will be a hazard if this material is widely used. Unlike the United States and Australia, the government institutes haven’t established a common standard about thermal insulation. More
