Abstract : A reinforced foam core acoustic baffle includes a pressure release polystyrene foam core, upper and lower steel reinforcing plates, a plurality of steel reinforcing rods, and a high-density foam skirt. The reinforcing plates are bonded to the upper and lower surfaces of the foam core, and the reinforcing rods are received through the core and are secured between the reinforcing plates so as to maintain the plates in spaced relation. The high-density foam skirt comprises a plurality of high-density foam panels which are bonded to the side surfaces of the foam core so as to overlap the upper and lower reinforcing plates. The foam panels are bonded with a watertight epoxy adhesive that forms a watertight seal with the reinforcing plates, and the foam panels further prevent the pressure-release foam from being, crushed inwardly at the sides.
