Have you guys heard of a new requirement, where you cannot install PVC cables touching polystyrene beads or sheets..
I belive there is some kind of reaction between the two,,
Maybe some one could confirm this??
the reason i say this is that this same plumber laid his cables in the polystyrene instaltion in the floor screed. i said i thought it wouldnt be wise and to use conduit or run them in the ceiling void..
