Vertical transition from a structural-sealant-glazed curtain wall to a concrete composite floor deck supported by structural steel framing. The head of the curtain wall incorporates a sill extension and is attached via manufacturer components to the structural frame, backed by mineral wool insulation and exterior gypsum board. The floor slab edge meets an interior seismic joint cover and fire barrier with smokeseal, flanked by an air and vapor barrier. Below the slab, non-structural metal stud framing supports a soffit with prefinished aluminum closures, continuous soffit vents, and integrated flashing adjacent to insulated glazing units.
