An extruded aluminum threshold rests on a continuous bed of sealant above a 24-gauge stainless steel sill pan flashing with fully soldered end dams at both jambs. The door assembly aligns with the curtain wall mullion and features a weather seal at the door bottom. A metal walk-off mat is set into a concrete floor depression with a compressible joint filler below. High-temperature self-adhered flashing laps over the under-slab vapor retarder upturn, coordinating with exterior paving control joints at a slope not steeper than one to two.
