Is the cement board sound insulation effect is good, or gypsum board noise effect is good?
Our sound insulation board 425 (cement board composite, thickness 13mm) and Zhiwei noise board 410 (gypsum board compound, thickness 18mm) compared to the noise board 425 sound insulation better!
The green sound insulation board 425 and the green wood safety board 458 (a gypsum board + a piece of glass magnesium plate composite, the thickness of 18mm) its Zhiwei noise board 458 higher sound insulation.
In general, sound insulation is mainly high frequency and low frequency sound, different materials on both of them also play a different sound insulation (personal life point of view, but I think it should be right).
Can not completely say that drops, in essence, the two almost no correlation, with the thickness of the material, density, and environmental accessories, etc. are still very different.
Gypsum board, because the gypsum board density is low, so the sound insulation is better.However, the cement board is also possible sound insulation is very good, such as foam cement, its density is smaller than the plaster, sound insulation is also better.
