About this detail

A clad metal scupper and 16-gauge metal sleeve penetrate the wall assembly, integrated with a FiberTite field membrane and vapor barrier flashing adhered to the wall. The roof assembly consists of R-20 insulation over a 3-inch structural deck, supported by a structural steel beam with a vapor barrier and steel angle. Wood blocking with a gypsum cover board is secured using 3-inch ring shank nails at 3 inches on center staggered. Mineral fiber batt insulation, backer rod, and a slotted insert are provided at the wall interface, with gaps infilled with firestop material.
