shed insulation using polystyrene sheets

Used a little off cuts to fill the small bits

Through the vapour barrier onto the studs. So they hold the vapour barrier holds on til yer fixing the OSB on.
Oh and make sure theres something to fix the OSB to, especially on corners.

Staple barrier to the studs
Screw roof to studs

I'd say you're a natural at this game. Just don't put any spun sugar on.

Once the OSB is fitted to one plane is there a stud to fix it to in another?
You often have to put additional studs/noggins in to fix the boards to, youll work it out I'm sure.

Do these board only come in 2 sizes?? 1.2x450 and 2.4x1.2

No middle ground at all

Yeah, that stuffs fine, just more expensive pers square metre, another option is just to cut the big sheets down to a manageble size (divisible by the stud spacing obviously) in the carpark of wherever you buy it.
Quite common for builders to break sheets/long lengths of timber especially down to more managable sizes before they go in the van, not many vans can for 4.2 lenghts of timber inside.

That’s a idea, I’ve only got a focus.

Works out £22.50 a sheet
