Abstract
A method and structure is disclosed for oriented strand boards that utilize a 3-layer, sandwich-type structural panel.

The core is either a continuous perforated mat or a plurality of individual chunks of compression resistant materials, and preferably contains voids to provide for a reduction in weight of the board.
