Finishing basement and want to place copper and pex heating pipes close to the exterior wall of the basement to maximize space with new walls in front of them. Planning to have someone spray closed cell foam 2.8" on wall walls so the pipes can be buried/insulated in the foam and behind framing. Plumber concerned with pipes close to basement wall. In Northeast, basement rarely drops below 55. I think plumber is lacking testicular fortitude. Is this ok to do?
