About this detail

A structural steel beam supports the balcony edge at Level 03, aligned with a painted steel channel support located at the beam centerline. Six-inch metal stud cripples spaced at twenty-four inches on center are mechanically fastened to adjacent studs and the steel beam. Exterior wall build-up continues with two inches of rigid insulation, one-half-inch plywood, and an air barrier carried uninterrupted past the junction. A one-half-inch plywood backing extends to the face of the siding above a wood soffit. The wood soffit material and orientation match the main exterior ceiling. Double quarter-inch backer rod and sealant seal the joint at the exterior transition.
