fancy breathable paper? (expensive) and expanding metal lathe mate you can buy it in rolls sheets or rib lathe with ribs running horizontal to keep it off the wall slightly, you can buy eml in galvanised or stainless , not sure about rib lathe though i think its stainless only mate
if you use both the paper still allows the wall to breathe and the eml gives you a key ............slightly over the top but i cant think of a more fail safe way to over render
