Where a structural frame has elongated spaced parallel framing members therein, longitudinally extending edges of which are substantially coplanar with one another on one side of the frame, boards of wood facing material are superimposed on the edges of the framing members, and interlocked with one another, as well as with the framing members, at male/female joints formed therebetween along parallels to the right angular coordinates of the frame in the plane of the edges. The joints take the form of tongue and groove joints, and in the case of those between the boards and the framing members, the joints are also dovetailed. Certain improvements in sheet metal clad wood facing materials are also shown, as is a process for making boards of sheet metal clad wood facing material from planks of wood which are only partially dried when they are put to use in the process.
