A steel profile integrates into the Tahu unit, secured with self-tapping screws and a preformed seal. A galvanized flashing duct wraps all four sides of the opening, including the head, jambs, and sill. A one-by-one security wire mesh attaches to the scheduled partition using a metal channel and security bolts. An FFSAM membrane applies around all sides of the opening to establish a continuous air barrier between the Tahu gallery and the data hall. A vapor barrier installs on the data hall side of the wall as required.
