Abstract: The construction of bearing walls is facilitated by use of superposed courses of planks that are characterized by a novel combination of composition, geometry and arrangement. These planks are composed of a homogenized dispersion of fiber and binder. This material has been found to have a suitably high compression coefficient, to be chemically inert as a practical matter from the standpoint of resistance to atmospheric conditions, and to be inexpensively produced, for example, from used newsprint and the like. The planks generally have identical dimensions, thereby enabling standardized production and ease of assembly. The planks generally are substantially greater in width than in thickness. Pairs of the planks are provided at matched end locations with aligned notches for the reception of inserts that establish spacing and weather-tight joints. The planks are nailed or otherwise interlocked in staggered courses, by which the integrity of the construction is securely maintained.
