Then either put battons on wall, celotex then plasterboard, creating an

You might find this a good solution, phenolic foam (Celotex equivalent) ,
plasterboard and vapour barrier all in one:

It has worked wonders on the solid walls in my Victorian solid wall house.
I would either dot and dab or battens with a small cavity, British Gypsum
have clear instruction on their site.

Sounds interesting, I expect it is expensive, and where to buy? Not seen it
in local builders merchants?
