I am in the process of insulating under our kitchen floor, the plan
being to fit the Celotex between the joists and fill any gaps around
the edge with PU foam. However, some of these gaps also have cables
passing through so just to check does PU foam react like polystyrene
with PVC? Secondly, does passing through 100mm of insulation have any
significant effect on the cable ratings?

Should also have added, that it does depend a bit on what you mean bu
"in insulation". The worst case is literally that - surrounded on all
sides by insulation. Some cases are less onerous however - say wan its a
cable against a conductive surface like a wall or plasterboard, with an
insulation covering. See the installation methods section he
