About this detail

A scheduled backdraft damper is anchored to a vertical 4x8 hollow structural section member per mechanical drawings. A bird screen is secured to the vertical framing using one-way security fasteners across a 1.5x1.5 horizontal hollow structural section member. The assembly integrates with a 6x3 galvanized and painted vertical hollow structural support beyond, traffic coating applied with a bent plate and drip edge, sealant and backer rod, and a two-piece trim extrusion by the insulated metal panel manufacturer. Mineral fiber board insulation is placed at the underside of the deck, and traffic coating is extended up the vertical hollow structural section and concrete curb to provide an end dam.
