This assembly details the interface between a curtain wall system and a structural steel floor slab at Level 03, situated at elevation 128 feet zero inches. A continuous steel angle coordinates with the structural steel beam to support the edge condition, while a water stop line aligns with the face of the sheathing. Three-inch extruded polystyrene twenty-five psi board insulation provides thermal continuity across the exterior wall plane. Three-and-five-eighths-inch eighteen-gauge metal studs with diagonal bracing at forty-eight inches on center reinforce the interior backup wall.
