I do not heat my basement, but I would still like to insulate the exposed the cement between the sill and ground.. What is the best way to do this?
So 4 things that I am lookong for..
#1 - I am thinking of using extruded foam board for the insulation.
#2 - What should I use to cover the foam? to weatherize it.
#3 - How should I attach to wall? Liquid nails?
#4 - How deep should I put the foam board etc in the ground?
