Thanks for your reply, it is not foil but heavy galv metal as it is walls from a reclaimed wall in cooler, it is open cell. No A/C and I'm in Muskoka,Ontario. Was thinking I would tape the joints as well.

Alright, not what I thought, but without AC there is no great risk I can think of with that. Galvanized steel will for sure be a vapor barrier, and if its taped you've got a pretty reliable air barrier as well it seems!
