About this detail

This wall section details a parapet roof assembly at the south entrance, constructed with a pre-finished metal coping capping a parapet wall framed by six-inch metal studs and a six-inch framed header. A mechanically fastened TPO roof membrane runs up and over the parapet wall with a continuous cant strip. The assembly incorporates spray-applied foam insulation and three inches of extruded-polystyrene twenty-five psi board insulation. Steel tubes and steel beams are coordinated with structural framing, aligning the water stop line at the face of the sheathing. The lower transition meets a curtain wall system utilizing a one-inch exterior insulated spandrel unit, backer rod, and sealant.
