Replacing Chipboard with 25mm Plywood

[sheslookinhot]

I have listened to advice and decided to replace chipboard floor with 25mm plywood. While in some ways more work, at least I can just rip the flooring up without chiselling the tiles off. Getting the plywood tomorrow.

Can I ask a further question. How should the plywood sheets, 2440mm x 1220 mm, be laid ? Running parallel with the joists or across the joists. I intend to fit noggins (do you think that is necessary) on plywood joins where they are unsupported by joists.

Thanks

personally i would fit them as staggered joints across the joists and well screwed down

you should not need noggins

Try and by flooring ply, this has the same type of T&G edges as chipboard flooring so you don't need noggins on the unsupported joists. Usually comes 22mm thick and 8x2 sheets, the brand I use is "sprucefloor" made by Wisa.
