Following a flat roof leak, I have a soggy ceiling with a big split in
it. Now that the roof is being fixed, I'm going to have a bash at the
ceiling myself: It's only about 2 metres each way, so what could
possibly go wrong? (!)

I'm going to tear it down tomorrow and leave it for a week for
everything to dry properly. In replacing, I want to take the
opportunity to put some insulation in there. Now, I understand that
it's best to use foil-backed plasterboard to control vapour but I
can't find plasterboard with both a foil back and a tapered edge.

So...What's the best thing to do? Use foil backed square edge, which
will either need skimming or a bit of luck to get a good finish, or
use tapered edge and stick some foil on the back? The latter sounds
attractive but I might be missing something - like what's the best way
of sticking foil to plasterboard?

Any suggestions welcome!

I have no comment to make about the plasterboard, however if you have any
electric cables in the roof space then have a look at

to make sure the insulaton will not affect their performance.
