Equal parts of warp and fill in fiber fabric. Construction in which reactions to tension and compression loads result in extension or compression deformations only and in which flexural loads produce pure bending of equal magnitude in axial and lateral directions.
To achieve balanced construction panels should be absolutely symmetrical from the centerline, i.e., use materials on either side, which contract or expand, or are moisture permeable, at the same rate.
A composite panel which is laminated in a fashion (usually two-sided) that resists warping when subjected to uniformly distributed changes in humidity.
A method of constructing manufactured wood products so that moisture content changes will be uniformly distributed and therefore will not cause warping. An example would be symmetrical construction of plywood in which the grain direction of each ply is perpendicular to that of adjacent plies.
