[arabicarabic20]

or only i need to put any type of plasterboard

I think this depends on the room it's in. I'd use a moisture-resistant backing if it's on an outside wall, and I think all of these products have a fire resistance built in. I'd use a tapered board slapped onto the gyproc adhesive dabs, then seal and tape joints and skim over when dry.

A cavity wall? 9" Block-work and brick?
Kitchen or Bathroom, use foil-check.
You need fire-shield protection? Garage or risk area?

Be a bit more specific (in fact, a lot more)
