It looks like Roxul Safe n Sound is only available in Canada. What is a comparable product in the US?
Or is 'pink stuff' with double drywall good enough. This is for a basement HT.

Thanks.

You can just use standard wall insulation. If you want a little extra, you can use R19 in a 3.5" cavity but not really necessary. Roxul will give a small improvement in isolation but not a lot for the money spent.

The big selling feature of SafeNsound is its fire rated where regular insulation is not.

Thanks... Do you recommend staggered studs for the walls that are not against the cinder block walls?

It wont hurt and really improves the sound proofing qualities of the wall.

It all depends on what the other side of the wall is exposed to. If it's going to be drywalled, then either do that, or better, build 2 separate walls and drywall only the outside of each wall. This provides better isolation and also deepens the insulated cavity which drops the resonant frequency of the structure.
