ABSTRACT:
A portable, free-standing sight and sound barrier comprises a covered core of a lightweight, resilient foam. The core is flexible because it has alternating wall and hinge portions. The hinge portions are thinner parts of the core, generally being between about 3/8-1/2 inch thick. Suitable core materials are polyethylenes, polystyrenes, urethanes, or mosaic composites of these foams. Suitable coverings are fabrics, foils, paper, or paints, depending on the particular use contemplated for the barrier.
