About this detail

An exterior door threshold assembly sits atop a terrace floor system featuring exterior floor tile over a concrete topping slab on metal deck. The floor assembly is supported by a wide flange structural steel beam sized per structural drawings, with a two-inch slab depression at the threshold transition. An exterior door per schedule with a threshold is set at the door opening, aligning with the face of the glazing system above. Below the floor slab, mineral wool insulation is installed above the bottom of soffit line, maintaining thermal and fire performance at the exterior transition.
