    I'm about to line the inside of the back of my garage to create an office space. (it's double length, but single width, ideal really for converting half of, we're never ever going to put a car in!)
    Figured I'd use 2x4, will be the right depth for 100mm Celotex.

    One detail though that my stepdad and I can't agree on (He's usually my port of call for these matters!) He says the stud should have 18 inch centres - surely that doesn't make sense, as the plasterboard it will eventually be covered in would need to find a stud at the 4ft and 8ft distances??

    I'm thinking surely 2ft centres to the studs would be what I need to cover in standard 8'x2' plasterboard sheets?

    What's the convention? Thanks!

    400mm, 450mm and 600mm centres will all work for standard size plasterboards, though 400mm and 600mm will only work with 1200mm x 2400mm boards and 450mm centres for 900mm x 1800mm boards.

    Personally we won't use 600mm centres, rather we would opt for 400mm centres.

    However at 600mm centres it will mean less cutting for you (celotex) but ensure you board it with minimum 12.5mm thick boards.

    Does this wall require a fire rating?

    If you know what size plaster board you are using then you could cut your self a piece of timber that length, and use it as a ruler its better than a tape for that purpose.

    Thanks for the replies. I think I'll go for 400mm centres, with 600mm noggins! That way it won't be too far between studs for strength and still slightly less cutting!

    A builder friend advised I could probably just use 3x2 not 4x2. Then cheaper 75mm Celotex. Def 12.5mm pasterboard.

    I was going to go all out on thick insulation, and thick plasterboard, but won't throw money away if I don't need to!

    While I'm on here - What size screws would I use for the studwork? Shall I get a few hundred 4x75mm? Decking screws perhaps will suffice? Nail gun would be nice, but I can't stretch to one!
    Also, how shall I fix the studwork to the wall?? Just by attaching it to the floor and ceiling, or does it need it's own fixing to the bricks, by frame fixers? This seems logical, but seems a huge job also! (I've just seen masonry anchors on ebay that don't need plugs, just pre-drilled pilot holes! Any good?)
