    I'd like to improve insulation properties of my bathroom so, as I plan to retile, I thought I could use some brand of tile 'backerboard'. However, I have only about 30mm to play with - can I fix the board straight onto the wall, or must they be mounted on battens?

    Second point - do I need a moisture barrier behind the board?

    thirdly, do I need to do anything with the wall that's hidden by the bath, to prevent condensation?
    Any tips welcomed!

    It is unlikely to do anything to improve insulation. Cavity wall insulation is your best bet.

    Any external walls use laminated plasterboard you can buy this from any decent builders merchants in difference thickness from manufacturers such as kingspan celotex quintherm etc

    b/board straight onto a solid wall with 30mm to play..

    marmox 30mm backerboard,plugged and screwed, sounds what you could be after.

    thanks tictic. That's reassuring. Know anything about PCS board, by Polyfab Coatings? Seems similar to Marmox.

    ('I know Best' - happy New Year to you too - perhaps 2010 will bring you a life. Then you won't have to skulk around DIY forums looking for ways to justify your desperate nickname.)

    if you go for the 30mm tho
    dont think you will be able to dot/dab,all tho you can,
    you will be bringing them out to much if you only have 30mm to play with?
    check you can plug/screw them mate,but think it said you can?..but double check ;)
