This assembly utilizes a sixteen-gauge metal upstand to accommodate movement at a building expansion joint. The system incorporates a metal flashing profile secured to the substrate with mechanical fasteners, featuring a slip-joint configuration that allows for a two-inch expansion gap. A backer rod and mineral fiber batt insulation are installed within the joint cavity to maintain thermal and fire-resistive integrity. The metal cladding wraps the edge of the concrete substrate, providing a continuous weather-resistant barrier across the expansion gap.
