About this detail

The assembly transitions from a cross-laminated timber roof deck with a concrete topping slab and glulam beam up to a concrete stem wall and metal C-H stud framed exterior wall. A single-ply roofing membrane is laid over tapered insulation with a hot-air welded manufacturer's standard flashing membrane extending at least three inches onto the roof surface. A twenty-two gauge galvanized sheet metal two-piece flashing with wind cleats ties into an air barrier, overlapping a termination bar and fasteners. Exterior wall layers include type X five-eighths inch exterior sheathing, an air barrier, drainage medium, and a three-coat portland cement plaster with a weepscreed. The interior features a one-inch gypsum shaft liner, batt insulation sized per Title 24 calculations, and flat strap backing for fasteners. A C-H stud deflection track is positioned at the underside near the structural glulam beam.
