Our house is an old solid stone cottage that was refurbish in the 70s by the previous owners reusing the old ground floor walls, ~500mm thick, where they existed and adding a storey and a half extension upstairs of cavity wall breeze block. All of this has a pebble dash finish.
The big question is how to insulate the house. Do we treat it as if the entire structure is solid stone, therefore needing breathable materials or with different treatment upstairs and down?
Downstairs at present looks like, stripping off the plasterboard; insulating with wood fibre boards between the framing, then replacing with standard plasterboard and skimming with Gypsum. Upstairs we'd strap the external walls and use something like Kooltherm to board our and again skim with Gyspum.
Any help most welcome.
