As per title really,

im after experienced professionalls to offer the advice on whether i should build my internal dividing walls with either 100mm Solid Dense 7.3N Concrete Blocks or build a 100mm stud wall and pack with 60kg dense Acoutstic Mineral Wool?

I'll be finishing with 15mm acoustic plasterboard regardless of wall construction method.

Im thinking stud an wool will give the better performance, but will also cost significatnly more?

Main reason for sound proofing, is to isolate a wash/cloakroom from the adjoining lounge/cinema room...
