Soundproofing a stud partition wall

[Yorks Lass]

Plasterboard is being removed from a stud partition wall between downstairs loo and kitchen and we would like to take this opportunity to soundproof the wall as much as possible. Limited by space (there is a door frame at 90 degrees with the wall) so am wondering if acoustic slabs or acoustic roll plus acoustic plasterboard would have much effect?

Any advice much appreciated.

Thanks.

Definitely worth putting rockwool/acoustic slabs in as a minimum. Acoustic boards if you’re going further, but some gotchas which can totally negate the effects (like what happens directly above/below the wall), lots of posts recently on here, worth doing a search.

We did this with the partition wall between our en-suite and and shower room. We took one side of the plaster off to route some new pipes and took the opportunity to stuff it with Rockwool RW3 and then two layers of acoustic plasterboard. Did a great job for us.

Thanks for your replies. We are going for slabs and unfortunately there isn't space for 27mm+ acoustic board so we are having to use 12.5mm soundbloc which I suppose is better than nothing.
Thanks again.
