About this detail

A pre-manufactured roof hatch is mounted on a pre-manufactured curb set above a concrete slab on metal deck supported by a roof beam with spray-applied fire-resistive material. The roof assembly includes a single-ply PVC roof membrane over a quarter-inch recovery board, self-adhered vapor retarder, and polyiso rigid roof insulation with inorganic coated-glass facers meeting a thirty-minute rating minimum. A steel angle is welded to the ladder with a safety post, and galvanized steel burglar bars fully welded at intersections are integrated alongside a smoke detector. A bent plate or edge of steel frames the slab opening per structural drawings.
