    Anyone know of good sound insulation for a semi-D. the parents are having terrible trouble with the neighbours, partys etc.
    is there any soundporoof slabs that can be put on to the party wall that will cure all? does such a wonderful slab exist?

    its a standard semi-detached, 9' solid on the flat party wall. wall is battened, slabbed and plastered. not timber framed.

    I would expect the trapped air between the battens on both sides of the wall is amplifying the sound. Plus, the battens are probably nailed to the walls therefore airbourne sound is transported through these nails into the party wall and back into the nails/battens/screws/ plasterboard/air of teh adjoining dwelling.

    You need to:
    1. interupt this direct link between dwellings
    2. removed the traped air amplifier.

    If you are willing to, you could remove the plasterboard, counterbatten and incorporate a quilted firebreglass type material, fix a cork or reconstituted rubber sleeve at every screw point, plasterboard and skim.

    if you do actually remove the plasterboard i would go the whole hog and render the wall with sand and cement . then wet plaster skim over .

    no voids , more density
