Laying floor of 8 * 4 sheets of OSB 3.
Plain board, not T&G.
It will take most of two boards long ways so there has to be a join.
I'm trying to decide if I should cut the ends to join in mid-joist (2" *
4" - so 1" supporting the end) or fit a couple of noggins between the
joists and butt the uncut ends up wherever they fit naturally.
This shouldn't reduce the insulation much as the Celotex will butt up to
the noggins on either side.
Easiest would probably be to cut to meet on a joist.
As there are only two long ways sheets I could have the uncut ends meet in
the middle of the floor.
Are there any benefits to the noggin route?
Trying to measure twice and cut once :-)
Cheers

T&G strengthens the joint and reduces flexing.
You'll be wise to joint them on a joist

The reason for using noggings is that if you don't you will be wasting a

lots of material.
This is why T&G is best, there is no waste at all and just as strong if you
put PVA glue in the T&G.
Also T&G comes in smaller sheets. easier to handle, & get in doorways/loft
trapdoors/less waste in cutting etc.
So large sheets are a bad idea.
Also proper flooring sheets are superior/stronger/more wear resistant for
the job and can be got in moisture resistant grade.
They are laid at right angles to the joists.
The offcut from one row provides the start for the next = zero waste.
