hi, I'm looking to put Sound insulation in the joist area between ground and 1st floor. Knauf Sound insulation is generally harder to find then Thermal insulation, and I'm wondering is there any difference? I only have 50mm of space to place the insulation into, and I'm thinking what if I just cram 100 or 200mm thermal insulation into this gap? Would that work, or is it going to behave the same as thermal insulation i.e. it requires full expansion to operate?
I can't find any information on Knauf's website as to what the sound insulation properties of there thermal wool is, and I'm thinking this may be because its simply the same product, but they want to re badge and sale as different?
cheers to anybody providing 'sound' advice.
