Basement wall insulation

last year


In an attempt to insulate the basement more, stop some mild condensation, create a vapor and thermal barrier and make it warmer, I am thinking of doing closed cell spray foam of 2 inches (5 cm) in the crawling space ( headers) at the top and the first top 2 feet of the concrete wall. After that I will cover the whole wall top to bottom with a typical pink insulation R12 and vapor barrier, all the way down to the slab. Is this a good idea? Will this stop most of the cold and all condensation?

I live in a cold Canadian climate where winters can reach -15C and colder.
