I'm about to put some new joist in my loft (onto the wallplates, parallel
and between the trusses) so I can have a proper floor that I can put proper
weight on.

The joist section I choose depends on the pitch, and I guess the pitch will
depend on the floorboards. Loft boarding chipboard from B&Q seems to require
support on a 450mm, but then it does seem quite cheap and nasty.

The green floorboarding stuff that the devlopers used seems to be of higher
quality, but I dont want to pull up my carpet just to figure what pitch the
joists they used are one.

So, doesn anyone know what the normal spec fo rthe green particle board
flooring is, and if i'd be able to use it on 600mm pitch joists?

Cheers
Chris

"normal" for a floor would be 400mm c/c these days.

600mm is too far apart for almost every flooring material, they need 400mm
max for floorboards.

And 'pitch' isn't the word you are looking for, it's 'centres' - pitch
refers to the degree of slope on roof timbers etc.
