elsewhere here, I've posted re: red-doing our heating to radiant.
but the bigger problem as has been pointed out to me by several contractors is the lack of insulation under the ground floor.
it's very tight crawl space. what are thee possibilities of spray foam?
would I be better of with Icynene or something else?
I'm in the NYC area. The floor is about 800 sq ft of somewhat accessible space.
