Abstract
A polymeric void-board is placed between adjacent horizontal layers of bricks to maintain an opening in a lower of the layers. The void-board is fabricated from a first relatively thin planar element having first and second surfaces having a plurality of parallel ribs extending from and generally transverse to the first surface and a second relatively thin planar element having first and second surfaces having a plurality of parallel ribs extending from and generally transverse to the first surface. The first and second elements are joined to one another with the ribs of the first element engaging and joined to the second element.
Claims24
A polymeric void-board for placement between adjacent horizontal layers of bricks to maintain an opening in a lower of the layers, the void-board comprising:
- a first relatively thin planar element having first and second surfaces having a plurality of parallel ribs extending from and generally transverse to the first surface;
- and
- a second relatively thin planar element having first and second surfaces having a plurality of parallel ribs extending from and generally transverse to the first surface,
- wherein the first and second elements are joined to one another with the ribs of the first element engaging and joined to the second element.
A method of making a polymeric void-board comprising the steps of:
- forming first relatively thin planar element having first and second surfaces having a plurality of parallel ribs extending from and generally transverse to the first surface;
- forming a second relatively thin planar element having first and second surfaces having a plurality of parallel ribs extending from and generally transverse to the first surface;
- and
- joining the first and second planar elements to one another with the ribs of the first element engaging and joined to the second element.
