This assembly sets an aluminum storefront base mullion and vision glass insulated glass unit upon a concrete curb adjacent to a close-mesh painted aluminum bar grating walkway. Below the grating, a gutter with tapered insulation rests over a waterproofing membrane and composite metal deck. The exterior wall features solid surface cladding with angled glued corners, supported by a wall bracket, stud, and L-profile framing. A ventilation gap is maintained behind the cladding with insulation and Tyvek commercial wrap or fluid-applied weather barrier, allowing one-inch open joints at the bottom and top for airflow.
