Evening all,
Having scoured the forum for hours and hours I'm hoping for a bit of sensible advice on my current project...
1890's mid terrace granite cottage in west Cornwall (renovation project) - upstairs bathroom with 2x external walls (1x granite with cement pointing, and lime directly onto stone internally - 1x red brick with cement render, and lime directly onto brick internally). No current issues of damp, these walls get a lot of rain and luckily wind which I think is helping keep them dry...
Builder has demo'd the bathroom today and the walls are dry (very happy), but they are not level so he's keen to add studwork and plasterboard (moisture/cementboard) onto that.
He's suggested using celotex in the studwork but I'm concerned we'll create a new condensation issue behind the plasterboard. I know it's not exactly an ideal sympathetic restoration (and very little budget remaining) but would Rockwool (suitable for stone walls) be a better compromise to mitigate against any future condensation? I will also have a new extractor fan fitted.
If anyone has any specific advice I'd be really grateful, as I've gone round in circles many times regarding a sensible and affordable solution whilst still doing right by the cottage!
Thanks so much! You guys rock.
