Generated explanation

Three wall sections compare an uninsulated solid masonry wall with interior and exterior insulation retrofits. The original wall has interior furring strips providing a 3/4-inch airspace, wood lath, and plaster. The interior retrofit removes the old lath and plaster and replaces them with an insulated stud wall finished with drywall. The exterior retrofit adds rigid polystyrene insulation and new siding, such as stucco, outside the masonry while retaining the interior lath and plaster. Each section identifies the inside and outside faces.
