The difference between calcium silicate board and Fiber cement board
The difference between raw materials: About Calcium silicate board, the cement content is relatively small, the material of it is to use sand and fly ash instead of cement. The cement content of Fiber cement board is natural much more than the calcium silicate board, so the durable performance of plank is better.
Difference in density: the density of the Fiber Cement Board is higher than the Calcium silicate board, the density of Calcium silicate board is around 1.2g/cm3 while the density of Fiber Cement Board is around 1.4g/cm3 or above. The density is different so the use is different
Color difference: the color of fiber cement board is the same color as the color of cement, and the color of calcium silicate board is light gray slant white
