    Metal nail ins vs metal ceiling anchor *advice please*

    Hello

    I bought some acoustic plasterboard, its quite heavy (around 23kg per sheet). The instructions said to use 65mm metal nail ins. I ordered these from a seller on ebay and they sent me the wrong thing, they sent me metal ceiling anchors. My question is, will they do the same thing and achieve the same result? Or are the nail in's stronger etc?

    The reason im asking is because the house is due to get plastered on monday so I need to get these boards up tomorrow!

    I can't find any in stock in any hardware store or builders merchants.

    This is a picture of the ceiling anchor they wrongly sent me:

    This is the metal nail in that the manufacturer of the soundboard recommends:

    Any input would be much appreciated.

    Thanks

    Maybe a bit of a spanner in the works from me, but... The point of acoustic plasterboard is that it still needs to be mostly isolated from the wall / joists that it's attached to. I used resilient bars and had the plasterboard screwed into them.

    If you attach the plasterboard directly into the wall with nail ins then there's far less physical dampening. It'll still work to some extent, but not quite as well.

    ok, so all those pictures come up blank for me..

    I assume your ceilings are bare ( rafter showing)
    and concrete beams/rafters I assume since using those?

    its this stuff: http://www.insulationshop.co/30mm_karma_acoustiwall.html

    it says to put it straight on the wall. The foam part will be touching the wall, I am also putting acoustic sealant around all exposed parts.

    The ceiling anchors they wrongly sent me should be ok though shudnt they? The principle is the same.. a metal bolt in the wall that takes the load of the board?

    I need to fit it all tomorrow for the plasterer coming on monday!!

    same here pics don't work as long as the fittings are strong enough and long enough I don't see why there should be any issues with them u could use adhesive if that stuff will stick to the acoustic boards.

    yeah if its on walls should be fine,

    Ah right, those boards! Yes on the walls they should be fine.
