RIGID INSULATION ASSEMBLY ABSTRACT OF THE DISCLOSURE A rigid insulation assembly including a plurality of panels of rigid insulation fixed in edge-to-edge relationship on a base sheet to form a continuous length of insulation material wound on a core member whereby the insulation may be readily handled and be quickly applied to a roof deck by unrolling the material. The core is of polygonal cross-section so as to define a plurality of faces about its periphery, and the panels in the innermost layer on the core are of substantially the same width as the faces with the panels in each successive layer outwardly from the innermost layer having progressively greater widths so that the joint lines between adjacent panels are located sub- stantially on radial lines passing through the corner edges between the faces of the core. Accordingly, the panels in the first layer lie flatly against the core and the panels in each successive layer lie flatly against the panel in the layer inwardly therefrom so that there is no danger of the panels being torn away from the base sheet because of a rolling effect. The panels have one edge with a convex cross-section whereas its other edge is con- cave in shape so as to receive the convex edge of the adjacent panel and form a V-joint Which provides better insulating characteristics, and the interlock between the panels provides a stronger structure.
