Thicker PB might help noise transmission from your "dinning" room...
Anyway, 1/2" (12.5mm) plasterboard is a better bet than 3/8 (9mm) as
it's a bit stronger, as well as slightly better fire-wise. It's not
a lot dearer, either. I don't use thinner PB - I think it's a false
economy. You can get fire resistant PB - this costs twice as much
as "ordinary", and has glass fibres in the mix. It is noticably
stiffer, too, and you can tell it's different when you score/cut it.
No reason for fire unless you require fireproofing between floors to satisfy
a regulation. In a normal domestic dwelling of ground floor and 1st floor
their is no reason to have a fireproof ceiling. I doubt if the doors will be
to fire retardent standard so a ceiling is not a problem. If the house has
to satisfy a regulation then it will be much more than the ceilings that
need doing. You usually put the thickness of board to suit the joist spacing
They certainly aren't - I've done mine with 9.5 mm board. Just who do
you think uses up all those great piles of 9.5 mm board in the B&M's and
thicker board will marginally reduce sound transfer, but not to any
great amount I would think.
As someone else has said, there is no need for this in the normal
domestic situation. There are of course situations where the extra fire
resistance is required.
Depends on the joists spacing I guess. Our joist are less than 450mm
spacing on the whole and it is no problem.
12.5mm board is significantly heavier than 9.5mm (about 25% I suppose).
If you are boarding a ceiling, esp. mostly by yourself, this makes a big
Suffering from a compressed neck by any chance?
In a similar vein, what are the top tips for plasterboarding a ceiling.
I guess exposed rafters are easier than adding to an existing lath & plaster
I have knocked up a couple of T props, which are slightly longer than the
room height. Lean one against the wall to provide a ledge to start from,
lift board, rest on head, stick in other prop, screw in fixings.
I've over-boarded a couple of lath and plaster ceilings -unless lots of
plaster has come away it's not a problem certainly preferable to
pulling it all down, though I accept it is a bit of a bodge i guess.
That's the sort of thing I do, though just lately - I'm just having
another room done tomorrow I leave it to the plasterers. A couple of
blokes who do it all the time can have the ceiling boarded in no time
and it doesn't really add very much to the final bill.
