Default Insulating around the supply cable

Following the recent thread about cables passing through insulation
it has left me with a dilemma regards the supply cable.

My supply cable emerges out of the sub-floor and passes through an
approx. 50mm gap between the first joist and the wall. However the
run of the cable is not vertical due to the alignment between the
entry point and the cutout the alignment is approx. 150 - 200mm out
and the result is that the cable forms a lazy S in the space between
joist and wall. This makes sleeving impossible.

Originally, I was simply going to PU foam the gap but the previous
thread has made me a bit cautious. I could possibly get some of that
flexible corrugated sleeving and split it along its length to get it
around the cable but suspect there would be gaps at the bends
allowing PU in against the cable. To my mind the gap in insulation is
too great to ignore so I would welcome any advice please.

foam doesn't affect the wiring chemically but the insulation may cause
overheating in some home wiring cases. I doubt this is relevant for a
short run of armoured or 100A tails.
