About this detail

The roof assembly features a roof deck and rigid insulation, transitioning to a tapered rigid insulation zone of two feet minimum width to ensure the protection board and thermoplastic polyolefin membrane remain continuous. A galvanized steel outrigger extends outward, with its bottom flange terminating at the exterior metal stud framing. The exterior wall incorporates four-inch metal stud framing with batt insulation, alongside gypsum wallboard sealed at the beam penetration. A curtainwall header is integrated below with a ten-inch profile, adjacent to an elastomeric transition gasket and a one-inch sealant joint. Metal panel finishes MP-1 and MP-3 complete the exterior envelope at the eave overhang.
