About this detail

A roof penthouse overhang and parapet junction features finished aluminum composite material panels with one-and-a-half-inch aluminum plates set in sealant at panel joints. The assembly is built over twenty gauge metal stud framing at edges of insulation and five-eighths-inch exterior sheathing, with a sloped eighteen gauge top track and three-and-five-eighths-inch framing at sixteen inches on center. The roof system incorporates nine-inch insulation sloped at a quarter inch per foot, maintaining a one-inch minimum at the edge, beneath a quarter-inch roof board and high-temperature self-adhering sheet membrane. The PVC roof system transitions with a heat-welded PVC clad galvanized metal L angle and manufacturer-specified panel clips. Additional structural support includes eighteen gauge bottom tracks and sixteen gauge four-inch wide metal plates secured to the deck with number twelve sheet metal screws at sixteen inches on center where framing runs parallel with flutes. Aluminum fasteners with slotted connections and neoprene washers secure the continuous soldered L angle at the corner.
