I've spent a couple of days removing manky old lath and plaster, rewiring
and replumbing.

My daughter was going to get a man in to plasterboard the wall and build a
new door frame for a new back door but having gone this far I'd like to see
it through myself.

I've not plasterboarded myself but can't see that it's gonna be too hard,
particularly if it gets a plaster coat on top.

Given that a) I might be working alone and b) the ceiling is 9ft high,
would I be best using 6x3ft sheets of PB?

Yes - I've just used these and they are very manageable. You can balance
one on your head whilst getting the first 3-4 screws in.


Would I stagger the joins across wall using a 6 + 3 ft piece followed by 3
+ 6 ft piece?

Yes.

And max centres of 450mm seem to be fine for ceilings for the 9.5mm IME
- but for walls you'd need closer batten spacing or go up to 12.5mm



For a kitchen/dining room (well away from sink & countertops) what
thickness and type of PB should I use?

9.5mm if you can get the battens close enough.

Do you need to achieve fire resistance to the room above? 2x 9.5mm is a
good way to do this (staggered joints).
