thermal lining paper on lining paper and ceiling?

Hi, I have a corner room exposed to the weather on two sides. It has normal lining paper that's stuck well, vertically hung. Can I put thermal lining paper over this? Also at the top on one wall the ceiling curves round to the flat part of the ceiling. This part very cold under the edge of the roof. It tends to get a bit mouldy. Can I extend the thermal paper up round this curved bit of ceiling? It's a stippled finish on the ceiling..would that prevent it from sticking? I'm not too bothered about aesthetics, just functional warmth.
