Concrete porch meets foundation insulation – detail
We are in Minnesota (Zone 6a). 2200 sq/ft single level, slab on grade.
Can anyone explain, or point me to a detail that shows a good way for a patio, porch or garage apron to meet the perimeter insulation of a slab foundation? I plan on 4″ (r-20) of perimeter insulation.
Is it as simple as removing the foundation’s 4″ of perimeter insulation the thickness of the patio slab and replace with 1/2″ expansion material?
