I have a brick built semi-detached house (solid walls not cavity) and want to soundproof a bedroom party wall due to noise coming through from next door. The approximate area is 8 sq metres. The wall is solid brick and plastered (not plasterboard). From researching this there seem to be 2 main options:
1) build an additional stud wall slightly out from the brick wall and use an acoustic insulation material in the stud wall, then plasterboard over. The problem with this is that it steals about 5-6 inches from the room size which I really can't afford to lose.
2) Use acoustic panels (Acousticel M20AD 20mm are the ones I've seen most commonly advertised), which are glued to the wall and then covered with 2 layers of 12.5mm plasterboard. This takes up no more than 2 inches of space, and is a lot cheaper too. I understand this is less effective than option 1), but the noise coming through is just general (TV, voices, walking on wooden floors, and not heavy bass etc), so this would seem to do the job and is my preferred option. Does anyone have any experience of installing/using these panels and are there any snags? Or other alternatives?
Typical price seems to be about £28 per sq m plus VAT.
