What type of plasterboard / insulation? Ask your questions and find answers on many subjects relating to plastering and dry lining

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!!

Sarah.

You can use aquaboard from wicks which is a water proof plasterboard for wet areas ie; bathrooms.If you want a warmer room batten the walls witht 2inch square wood and put insulation behind the aquaboard.If the room is still not warm enough i suggest using under floor heating which is a lot less hassle than another radiator.

there is a type of waterproof board available but it is a little expensive as far as i know your best bet is to talk to your local builders merchants about the availability and cost of such a specialist board, or you can use normal plasterboard and add a little waterproofing mixture (available from all builders merchants) to the skimming water to help protect against the moisture this should not affect the working time of the skimming. Standard fibreglass of 100mm thickness should be fine for your stud cavity
