I would like to do three partitions in the room, with fiber cement board, gypsum board, fiber calcium silicate board which is better?
I think two kinds of almost the key is the role of fiber from the absorption of sound. If you can not knock the sound, you try thick on the line.
Generally with calcium silicate board inside the installation of noise insulation layer, or choose the best calcium silicate board, fire and water
You need to use the wall inside the use of professional insulation materials, or in specialized use under the special sound insulation board
If you want to recommend the use of fiber cement board or calcium silicate board, the two boards almost, if you say the sound insulation, then these three boards are not special noise board
