ABSTRACT:
An upstanding side wall comprises wood plank members having opposite planar outwardly facing vertical surfaces. The longitudinal side edges are bifurcated symmetrically with respect to a vertical central plane bisecting the two planar surfaces. The bifurcations are curved in horizontal cross-section to form a pair of curved tongues with an intermediate concave curved recess between the tongues. Each recess receives a mating tongue of an adjacent vertical plank member. Each member is symmetrical about the central plane and also about a midplane perpendicular to the central plane and midway between the bifurcations. Alternate members may comprise members corresponding substantially to a half of such a member cut along the central plane. A low density soft foam sealant is applied in a groove at the bottom of each recess.
