Fiber cement board is a kind of board with fiber and cement as the main raw materials. It is divided into low density cement board, medium density cement board and high density cement board according to different densities. Its length is generally 2.4 meters, its width is generally 1.2 meters, and its thickness varies from 4-12mm. Fiber cement boards are also divided into asbestos-containing and asbestos-free ones. The common ones in China are generally asbestos-containing, because the price is relatively cheap. Then if the project requires asbestos-free, we can also customize asbestos-free boards.

Low-density cement boards are generally used for partition walls in buildings, just like plasterboard. Medium density cement board can be used for the suspended ceiling of the building. High-density cement boards can be used for building exterior walls and floors, etc. It is fire-proof, moisture-proof, and heat-insulating itself, and can be used as thermal insulation board for exterior walls, exterior wall hanging boards, attic boards, etc. Fiber cement board is resistant to high temperature, and its performance is relatively stable in high temperature and humid environment, and it is not easy to bend and deform.

Then calcium silicate board is also a material that is very similar to cement board, but due to different raw material processes, calcium silicate board is rarely used on exterior walls, and most of them are used on interior walls, just like gypsum board. Some people can’t tell the difference between calcium silicate board and cement board. They are slightly different in color. The surface of calcium silicate board is gray-white, and the surface of cement board is gray-blue. Please pay attention to this point when purchasing.
