The sound board is fixed to the wall like anyother plasterboard, in my case it was on top of a stud wall (wooden battens and noggins). I used the black (phosphated) plasterboard screws (Screwfix do them, as do Wickes) at about 30cm intervals around the edges and in the centre lines where the studs are (obviously).

Because this board is so heavy, I put in studs at 600mm intervals to take the weight and stop the board bowing in the middle. I used the Wickes 47mm x 47mm planed timber as it is heavier duty.

It is outside my experience, but I guess that on bare brick, mortor dabs would also be ok to fix it.

I have had the board plastered with no problems what so ever - I would recommend plastering as the finish will be better for painting rather than straight on to the board.

The difference between normal Plasterboard and Soundshield Board is 4KG.

Normal Plasterboard weighs 8KG per m2

We would not suggest using the 'Dot and Dab' method. We would suggest removing the old plaster or using a mechanical method of fixing such as plasterboard screws.

This board has the most acoustic insulation of the plasterboards that we supply.

We suggest fitting the soundboard on the outer wall, just because you will require a moisture resistant Plasterboard in your ensuite for obvious reasons.

We would recommend using either our Mositureshield Tapered Edge (Product Code 190540) or any of our Aquapanels (Product Codes 224658 and 220561) Both listed above are designed to be used in area where there is more than the usual level of humidity.

We can confirm that this would be fine to be fitted to a ceiling.

It is not recommend to add a second layer to a dot and dab system. This is because the dabs are only tested to hold a single layer. Even if you use screws these could hit the dabs and weaken them. If you are able to screw directly in to the back ground material this may be sufficient to hold the two boards. Other than this a stud lining or metal work and batten system would be required.

We are unable to offer a single a sound level reduction measurement on our Soundshield board.

However we can offer a sound level reduction measurement on your complete build.
