where to insulate on slab on grade reno
I am making use of an existing slab and converting our detached garage into a dwelling unit.
I am adding a strip footing along the perimeter and insulate on the top of the slab, with a floating floor on top of that. The plan is to turn this into a thicken edge slab, essentially.
Is there a benefit to insulating the exterior of the footing/foundation wall, up to the top of slab.
Would it make more sense to insulate on the inside of this wall or will it not add anything where there is already insulation on top of the slab?
