Generated explanation

The cross section shows insulation installed in framing on the interior side of a basement foundation wall, with exterior backfill, a footing, and a basement floor slab below. A basement window interrupts the wall above grade, and insulated floor framing and wall framing are shown above it. Green check marks identify easier treatment of basement windows, small additional cost when finishing the basement anyway, and better basement-wall drying potential. Red crosses identify the difficulty of detecting and pinpointing basement leakage and the need to work around obstructions and wall penetrations.
