Thank you for all the help regarding warm roofs, fingers crossed that is all figured out now
We also will need to insulate some of our walls, which are 70mm solid spruce. We're working on the basis of 75-100mm PIR.
From discussion on roofing about VCLs, my understanding is we'd now need to put the VCL on the inside of the PIR to prevent warm room air hitting the logs and causing condensation which would be particularly bad on a timber wall?
Someone suggested we should employ an air gap, if so where and why? I'd assume we'd have interior cladding, VCL, PIR, external wall?
We are discussing whether the internal finish should be plaster, or cladding. I imagine one builds a standard stud wall, fits PIR and then fit the cladding material on the studs just like building an internal wall in your house - is that all there is to it? Would you sheet the entire wall with VCL on top of the studs/PIR then clad on top of that?
