Hello, i'm currently about to build an L shaped stud wall for a bathroom, with a door frame included. It needs to be insulated and sound proofed, plus moisture resistant. What type of plasterboard should I get? It will just be painted, not tiled. And should i fill the void with insulation of some type? Any suggestions?
And also i want to insulate the two other walls, as they're exterior single brick walls, again what type of plasterboard is best to get for that? That board will be fixed straight onto masonry - is that ok? Again just painted, no tiling.
I want decent insulation as it's a downstairs bathroom, and a single brick extension on a Victorian house, and COLD! But it's only a small bathroom so i don't want hugely thick plasterboard either.
I'd REALLY appreciate some advice, never done this before but can't stand being freezing cold in the shower any more!!
