About this detail

The base of an exterior cement plaster wall meets a concrete building slab and a sloped architectural topping slab. The exterior wall framing consists of cold-formed metal stud framing with batt insulation and an interior gypsum board finish. The exterior features gypsum sheathing, a fluid-applied membrane air and water barrier, and two-inch rigid insulation with a twenty-five psi minimum compressive strength. A sixteen-gauge minimum thick cold-formed metal furring is thermally isolated from the metal stud framing to support the exterior cement plaster over welded wire lath. At the base, a twenty-two-gauge stainless steel flashing is set in a continuous bed of sealant and mechanically fastened, integrated with self-adhered flashing and a painted, extruded aluminum l-mold. The floor assembly comprises a four-inch thick architectural concrete topping slab over a drainage mat, waterproofing, and a sloped architectural slab with a sealant cant at the joint.
