So, I’ve previously used Rockwool PROROX SL930 (RW3) (60kg per m3) high density acoustic mineral wool in a ceiling. It’s expensive and blocks out noise. Would you suggest using the same in all ceilings or something different? I want to insulate them now I’m having new joists and there was previously no insulation.
How about 4 and 3 inch stud walls? Do they need insulating too? A builder said to not bothers as it “gets in the way” when running cables and plumbing.
Would you suggest 12.5mm acoustic dB board on stud walls to reduced sound travel?
Thanks for your help and advice as always.
