Hi,
Is expanding foam safe to use in contact with PVC sheathed cables?

Thanks

I'd err on the side of caution.

PVC cable in contact with polystyrene tends to melt the polystyrene. I
imagine it would do the same with expanding foam.

Perhaps worth calling/emailing the manufaturer of the foam and asking
them?

You may have the issue that it will insulate the cables, and reduce
their current carrying capacity. The expanding foam has quite a good U
value.

Compared to the problem with PVC plasticisers damaging polystyrene foam,
yes.

Yup... at least there is no leaching plasticizer pproblem. However you
may need to apply derating to the cables current capacity if any length
of it is buried in the insulation.
