A two-and-a-half-inch by seven-and-a-quarter-inch glazed aluminum curtain wall system interfaces with the concrete floor slab. Perimeter mineral wool firestopping is installed at the slab edge under the floor closure angle, accompanied by additional mineral wool firestopping. One-and-a-half-inch medium density, closed cell spray foam thermal insulation is applied above the assembly. A horizontal integrated wall panel line is indicated with curtain wall frames positioned above and below. Angle connections and their specific quantities are designated to be determined by the curtain wall engineer.
