Polymeric void-board for layers of bricks

摘要

An extruded polymeric void-board (12) is configured for placement between adjacent horizontal layers of bricks (14) to maintain an opening (22) in a lower layer of the bricks. The void-board (12) is formed as a planar element having parallel ribs (26) which extend from and generally transverse to a first side. The ribs (26) have a predetermined height to width ratio, a height that is less than a thickness (t24) of the planar element and are formed parallel to one another. A method for forming a bundle of bricks with the void-board is also disclosed. The board (12) is preferably of polypropylene, polyethylene and a fibrous or particulate filler. Weakened regions (36) may facilitate removal of vertical layers of bricks.
