Hi, I have a cathedral roof with 150mm joists and gib over the joists. I want to insulate it so I've screwed battens across the bottom of the joists and blocked out between them so that I can screw sheets of gib up. I intend to pack the space with pink batts but I don't know what to do about the existing ceiling. Should I knock out the old gib, which will be above the pink batts, to allow any moisture to evaporate into the roof space or can I leave it there? I intend to seal and paint the new gib so I think this won't be a problem.
Thanks,
NC
