Many thanks.


Pointless unless you can get a couple of inches of polystyrene in there.

Foil is not insulative., Its conductive. Al is the most conductive metal
for its weight there is pretty much.

This is not intended to be contentious, just a question. If putting
foil behind a radiator then papering over reflects heat back would not
the same beneath a floor have the same effect?
