are you sure it's polystyrene and not polyurethane plaster board?

Both types of plasterboard will react with with standard PVC cable..
You can use either type of capping to protect the cable.
there is also some non migratory cables on the market that don't react

Its a white insulation, rather than a blue or yellowish insulation? Looks like it without picking at it.

Assuming you were not making a good pun, I was told that the plasticizes reacted with the polystyrene and therefore the capping needed to be tin.

They changed the chemical makeup of the polystyrene used for building BS insulation purposes many years ago now, because of the plasticizing effect on cables and some types of pvc pipe. It shouldn't now be a problem, though many are still not convinced!!
