Protecting skirt insulation?
I am finishing up the exterior insulation on a monolithic slab detached garage project. In addition to the sub slab and vertical perimeter insulation I am placing skirt insulation around the building. I am using Formular 300 xps rigid foam for this purpose and will be backfilling with top soil that was excavated from the site. Should I be putting anything on the skirt insulation to protect it prior to backfilling with soil?
