We are about to put in a new floor into our lounge and have decided to have
a wooden floor with carpet on top. The joists are all in good condition and
damp proofed though the sub floor is damp. I'm thinking of laying a flooring
grade chipboard floor (cos its a lot cheaper than other options) - grateful
for any experioence on problems and views on whether I should really go with
plywood or softwood. I'm told I'll have to acclimatise softwood - having no
floor to sit on for 2 weeks doesnt appeal!
Flooring chipboard is tongued-and-grooved so would self-seal against
droughts and dirt. Softwood flooring would certainly need to be
acclimatised, although you wouldn't have to take up the old floor first,
until you were ready to lay. You would need flooring cramps to press each
piece hard against its neighbour. Plywood doesn't have tongue and groove so
you'd need to do this yourself.
All in all I would have thought flooring chipboard was the best, if you are
going to carpet over it.
I would too, just get the moisture resistant green board, costs a few pence
more but looking at the offcuts I left outside for ages when building some
years ago there was no sign of swelling. I screwed our boards down and left
maintenance hatches for access while I was at it.
When you put the chipboard down do you have to leave any expansion gap
between the boards and thw wall, or can these butt up ? I will lay skirting

We butted the boards hard together during assembly then as I mentioned
screwed to the joists. As for the wall to board joint, we left around 1/4
inch gap. We studded walls and placed extra insulation between wall and
plasterboard so our skirting was some distance from the actual wall.
Personally I would not think it to be an issue other than draft / vermin
protection. Now the extension was built 10 years ago and we do not have any
problems with squeaky boards even though used daily and exposed to large
variations in moisture levels and temperature. Floor area was 5m x 8m. so
the boards have remained very stable We have in January replaced our
daughters bedroom floor with green moisture resistant T&G flooring
