Frost Protected. This method only works with a heated structure. It relies on the use of two sheets of rigid, polystyrene insulation-one on the outside of the foundation wall and the other laid flat on a bed of gravel at the base of the wall-to prevent freezing, which is a problem with slab-on grade foundations in areas with frost.
