About this detail

An aluminum curtainwall jamb adjoins a two-inch composite metal wall panel system backed by metal stud framing with four-inch mineral wool insulation board and five-eighths-inch exterior gypsum sheathing. A fluid-applied air and vapor barrier is applied over the sheathing, backed by self-adhering aluminum flashing and a J girt provided by the ACM manufacturer. The assembly transitions to the interior with gypsum board to deck and a ceiling referenced on plans. At the exterior joint, a prefinished metal flashing matches the ACM, incorporating a weeps tube, three-quarter-inch sealant joint, and a three-quarter-inch backer rod with sealant. The head detail features an aluminum curtainwall system aligned with the primary seal at the face of the sheathing, gasketed tear-away L-bead, and decorative sealant.
