What is the proportion of gypsum board?

Answer:

Gypsum board generally used surface density measurement, for example: 9.5mm thickness gypsum board, the national standard requires its surface density to be less than 9.5Kg / m2, but most of the better quality gypsum board density control in (6.5-7.2) Kg / M2. If compared with the density of water, the proportion of ordinary gypsum board is less than water. But the refractory board due to gypsum core inside the addition of glass fiber, depending on the amount of added, the density may be greater than the density of water.
