Cheers John - I am aware of that TPS v polystyrene situation . Actually noticed a bit in the old wiring looking a bit different where it was in direct contact - just seemed a bit harder than normal .Don't think it was going to do much else so nothing really to worry about in existing vans (just my opinion)
I am using polystyrene for insulation however I will use a barrier to keep the TPS cabling away.
