Silicon calcium board can be used for external walls
The main reason is its advantages: light, moisture-proof performance is good, easy to change color, high hardness, good sound insulation performance. The calcium silicate board also has obvious shortcomings: the installation is not easy to replace, the installation of the use of iron keel, the price is more expensive and easy to break, slit.
But now there are external walls with calcium silicate board, but from the cost point of view, the proposed external walls or do not use calcium silicate board
Calcium silicate board from the density classification, can be divided into low, medium and high three categories. While the use of outdoor, then the general high-density. Matsumoto's high-density calcium silicate board is processed by high temperature autoclave and special technology. The water absorption is low, there is impermeability, and there is no wet mark and water droplets on the back of 24h. It has water and moisture resistance The After high temperature pressure, the formation of calcium silicate board can be closely balanced internal structure, impact resistance greatly improved.
Calcium silicate board is less to do outside the wall panels, are generally decorated with interior walls
