I am removing an old lath and plaster ceiling in both downstairs and upstairs but confused as to which type is best. My builder is suggesting the smaller size, as he says that's common in ceiling and 12.5 is mainly for walls
However, I think he should fit the larger depth, at least in downstairs celing, for extra noise insulation, even I'm going to fit rockwool between the joist for downstairs.
All the ceilings are being replaced. He has ripped the whole house old ceiling and putting plasterboard and skimm over it.
Is he right in choosing 9.5mm over 12.5
