Question:

Which kind of soundproof cotton is the best for decorative gypsum board partition ? Mineral rock wool or glass wool?

Answer:

Glass wool has better effect of sound insulation and is easier to construct but more expensive than rock wool. But there is no inspection report so there is no quality assurance if you use it.
The upstairs answer is wrong. rock wool is made of basalt through melting and spining, rather than asbestos. Asbestos and rock wool are two different things. Please check soundproof walls. From the aspect of soundproof effect, it is better to combine rock wool and glass wool, with the former insulating low frequency and the latter insulating high frequency. Unit weight should be above 80k. In terms of construction, they are similar. Rock wool may be more difficult for construction workers but it is cheaper than glass wool.
Materials must be completely sealed to the inside wall. The price is about 40-60 yuan per square meter. Dust will cause respiratory allergies, so pay attention to protect the construction workers. Construction methods are the same. Official places are prefer to 80KG per cubic meter. They are all made up of brittleness fibres, thus needing materials with high density to get a better effect of sound insulation. Rock wool and glass wool are similar in term of overall performances. Do not pulverize. Usually high-grade. Sound-absorbing effect is reflected in the wide-range noise reduction. The price is about 55-80 yuan per square meter. It can effectively inhibit sound transmission generated by resonance when being attached to the back of thin plate. High sound barrier mat is reflected in its high damping performance. If it is perforated ceiling, glass wool must not be used, for middle and low frequency. Without exhaust vent, it may cause pruritus in construction. The advantage of the product is more environmentally friendly. But the price is much higher. Now it is said that gradient sound absorption wool has the best sound insulation effect on current maket. It can be directly put on the keel gap space, to reduce high-frequency sound effectively. This material can cause skin allergies, so sealling board at the outside.
Of course, they are very profitable in China, which is asbestos material. American Armstrong's failure is such an example. You can search the hazards of asbestos online. While glass wool is much better.
