Hello, I would like to ask, I would like to do three partitions in the room, with fiber cement board, gypsum board, fiber calcium silicate board which is better?

One is better sound insulation, the second is the best not to knock the hotel that kind of boom pound sound. Is there a good recommendation? Thank you more

General use of calcium silicate board inside the installation of noise insulation layer

Or choose the best calcium silicate board, fire waterproof

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.

If you want to use a fiber cement board or calcium silicate board, these two boards are similar, if you say the sound insulation, then these three boards are not special sound insulation board, you Need to do in the partition inside the use of professional insulation materials, or in specialized use under the special sound insulation board
