Abstract 1. A structural product comprising: two flat paper board or fiber board panels disposed in spaced parallel planar relation to one another, each of said panels having a plurality of partial perforations therein defining flat tabs each of which is bent about a hinge line constituting the uncut portion of its associated partial perforation, each tab extending in a direction substantially perpendicular to the plane of its panel toward the other of said panels across substantially the entire space between said panels, each of the flat tabs extending from one of said panels being disposed in planar contact with and substantially completely overlapping planar relation to a corresponding tab extending from the other of said panels, said overlapping contacting tabs being attached to one another by adhesive or mechanical interlock to form intermediary members each of which has a thickness at least equal to the combined thicknesses of said two panels, said intermediary members extending at right angles to the planes of each of said panels to retain said parallel panels in fixed position relative to one another.
