ABSTRACT:
A stressed skin panel comprising a pair of elongate planar plywood sheets which are spaced apart, with a uniform distance therebetween, by means of longitudinally extending, internal joists. Attached to the inner surface of one sheet is a body of heat insulation material, the thickness of which is such that a continuous ventilation passage is defined between the heat insulation material and the inner surface of the other plywood sheet. Both of the two plywood sheets are cut back at both ends to expose the internal joists, the extent of cut-back being less in the case of the second sheet than the first sheet so that the second sheet overhangs the first sheet at both ends of the panel. In use, the exposed end portions of the joists receive fixing means, such as bolts, for mounting the panel in an operational position.
