Sound plasterboard

papayalady
5 years ago
I'm thinking of putting up some 15mm sound plasterboard on my party wall between my bedroom and the neighbour's. It's a single brick wall and the little boy next door tends to have tantrums late at night and I hear every sound when mum raises a her voice to tell him off! I've got chronic fatigue so really need my sleep! I can't fit a stud wall as I can't lose the space.
Has anyone got any experience of using sound plasterboard to block sound?

    I doubt that a single layer of plasterboard would achieve anything. if you could loose around 45mm of space then there are rubber panel solutions which would be more effective.

      or if space is really tight then there is a solution with 1 or 2 sheets of plasterboard plus thin rubber sheet, but effectiveness seems to be unknown.

      Does either of you have bare floorboards? It seems to me that sound travels more that way. If you have bare floors consider carpet.

      If they have bare floors have a board up near your party wall and use spray foam insulation along the wall between the joists.

      You should also consider if sound is traveling through loft space and add insulation up there.

      This theory all comes from my experience with neighbours. My cellar is not plastered and in my cellar I can clearly hear my neighbours on their ground floor and some of that sound travels to my ground floor.

      I would recommend something far denser than spray foam. I filled that gap with acoustic slabs, Rockwood RW3 or similar. Easier if your joists run parallel to the party wall and don't cut into it of course.

      Hmmm, my mind wonders if a layer of bubble wrap, or more like the insulation sheet bubble wrap sandwiched between the plasterboard and wall would make this idea more effective and also not take a lot of space?

      Thanks all for your advice. All floors have carpets upstairs, but as it's a single brick party wall sound carries

      Bubblewrap - I think I'll look into this as well as the rubber sheet/plasterboards solution.
