In the next week or so I'm going to get my bathroom wall plasterboarded on to battens .This is an outside wall and to help heat retention I was proposing to put insulation material between the battens . It's a cold room during the winter . I take it that there will be no problems doing this and is it the same stuff that gets used for loft insulation I should be using .?? I'll be securing it (at the top at least) to stop it slumping down .
