Styrofoam insulation of a foundation....
Styrofoam insulation of a foundation....
(OP)
Has anyone seen a styrofoam lining used to separate a residential walk-out foundation from the poured slab on the inside? I couldn't think of any reason why this would be done... See attached photo (wall to slab interface shown). I'll post a sketch if anyone is unclear.
Pay no attention to the window on the left hand side - That's just waiting to be installed.

I really dislike this particular type of FPSF. I don't think it is a wise detail for the serious cold of come Canadian climes, including Ottawa. Why not simply double the insulation on the outside? I looked at the amount of insulation involved, and the total is MORE for the installation all under the slab and to the edges versus a second layer of insulation on the outside.
