Hello:
Is there any reason NOT to place 2 inch thick rigid foam insulation horizontally 2 feet wide, buried 12 inches deep, all around the perimeter of my 7 foot cement block foundation?
3 feet of the foundation is above grade and will be covered with rigid foam insulation to a depth of 1 foot below grade. This will then be covered with some sort of protection like, say, stucco.Any thoughts on this would be appreciated.
Rob.
