Exterior wall head flashing and metal foam closure assembly at a junction with a perimeter window mullion and a suspended acoustical ceiling. A three-inch metal and foam closure is riveted to the panel and set in sealant. Primary and secondary weather sealants provide a continuous thermal and moisture barrier above the head flashing, which is fabricated from one-eighth-inch formed brake metal finished to match the perimeter mullion. Interior finishes include a five-eighth-inch gypsum board suspension system secured with an acoustical ceiling tile wall angle at the attached side.
