Extension built c1960... external walls are 9" potblocks.. heavy ones.
Groundfloor onto concrete.. bathroom having a full ripout... including ceiling.
Am having PVC(?) panels fitted to all walls (not ceiling)
Can these PVC panels be dotndab straight onto the external wall or will it need a thermo-plasterboard on it first?
I was thinking 10mm on the windowed external wall, and 5mm on the rest...
