| Sheetrock, in the US, is all the rage. It has density, flexibility, holds paint well and is fun to look at!
440 soundbarrier [homosote] has many usable applications in building a residential structure...but not specifically a recording environment or sound isolated type space as you have mentioned.
So sheetrock is your friend in this area. You could use a layer of OSB, on the frame first then install the rock. This would help you in a few ways, make it possible to hang future treatments without hunt and pecking a stud and it will also give the wall some structural integrity.
But it may not be in your future. Sheetrock is.
I just read your topic heading more clearly. Insulation isn't a sound isolator by itself. Mass is what you want to stop or control sound. Insulation is often part of the wall assembly AND part of the treatment of the interior of rooms.
But it is not mass and has no density to speak of for your first point of concern, that is, containing sound. But you would still want to install it into the open framing members to damp the sheetrock panels.
