Funnily enough, I was going to say 'laying Rockwool' too; in a roof
space where the pitch of the roof above was incredibly low and shallow,
necessitating me lying full length on crawl boards wiith push-sticks to
lay the stuff. But fitting it *above* you?? Yeuch - I think you've
beaten me there!

I was in a shed the other day (Homebase) and they did a rockwool /
insulation roll that came pre-wrapped in a plastic film, so its only when
you actually cut the roll to length that you expose the fibres. There
appeared to be plenty of expansion room to the film, so it should fill
out fine.

Jobs like this might never be quite as bad again :-)
