I'm looking into adding soundproof panels to the wall between me and my neighbours (it's about two layers of bricks I think, and can hear the neighbours tv when they have it at normal volume). The house seems a fairly standard 60s residential terrace.
The panels I'm looking at weigh 20-30 kg per square metre, to do all the walls I'd like to do will add up to around 1500kg added to the house, with 500kg hanging off two walls.
