Single-story house in northwest Montana

user-6466307 | Posted in Energy Efficiency and Durability on

Hello. I am preparing to build a single-story house for my wife and I in northwest Montana. At this point I am considering a block foundation with a slab as opposed to a crawl space. Would I insulate the inside of the foundation so the outside of the framed…?

    Looks like you put the title in the comment window, and the question in the title (which got truncated.)

    As Dana guessed, it looks like your question was truncated. It sounds like your foundation will consist of CMU (concrete block) stemwalls surrounding a slab on grade. See the image below for an insulation detail for this kind of slab-and-stemwall foundation.

    More information here: "Insulating a slab on grade."
