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.
Yes. I've done it with 8x4s but smaller is a good bit easier.
Would I stagger the joins across wall using a 6 + 3 ft piece followed by 3
+ 6 ft piece?
Yes.
any way you like, as long as it's all covered and there are no thin strips.
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.
I would never consider 9mm on walls. 12 is far more robust and very little more cost.
Haven't checked the batten spacing yet. Guess I probably should. ;-)
12mm works with any normal spacing
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.
definitely not, use 12 on walls minimum. 9 is weak & offers near zero sound stopping.
Re noise, even with 12mm you'll find the soundproofing rather inadequate. One easy way is to slap a load of wet plaster on the rear PB before fitting the front PB, with the aim of making the rear leaf thick & heavy.
Do you need to achieve fire resistance to the room above? 2x 9.5mm is a
good way to do this (staggered joints).
Ah, good question. I guess it probably does what with it being a kitchen
and a separate flat upstairs. I guess this would apply to the ceiling as
well if/when I do it?
In that case you need good fire & sound resistance. A sheet of PB absolutely won't cut it on either point.
