    is this OK?

    I want to plug up some gaps between my floor and skirting board and it's right where cables are chased up the wall to sockets hence you can see the cables in the gap.

    Expanded polystyrene is known to be a no-no adjacent to PVC cables as it breaks the PVC down over time. Does it say on the can what type of plastic the foam is made of? Could be one for an industrial chemist's forum.

    It is because of your comment Clooney that I asked as I am aware of this.
    It is exactly the stuff that you point to lastword so I'll get on with it.

    Thanks very much to you both.

    On a job today and seen twin and earth clipped direct to a joist and what looked like the plasticizer (<----spelling?) of the clip migrating in to the sheathing of the cable.

    we know about polysterene granules having the same effect

    Anyone else had this
