This assembly utilizes a central corner mullion to join two curtain wall segments at an angle. The curtain wall framing is installed as scheduled, with glazing units secured within the aluminum extrusions. A formed break metal cover is applied at the exterior corner, with sealant applied per the manufacturer's specifications to ensure a weather-tight joint. The interior side of the corner mullion is also finished with formed break metal to provide a clean transition between the two wall planes.
