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!
