ABSTRACT OF THE DISCLOSURE The present invention provides a roof decking for use in supporting a built-up roof structure, said roof decking being formed by a plurality of abutting panels laid across a plurality of laterally spaced, substantially parallel purlins supporting the roof structure, adjacent longitudinal edges of the panel extending between the purlins and adjacent lateral edges of the panels extending along the purlins, each said panel comprising a framing including longitudinal linear rigid edge members having a lower faceboard fixedly attached thereto and an upper faceboard fixedly attached thereto to define therewith a central core cavity which is filled with a fire resistant heat insulation material, the longitudinal edges of the faceboards extending beyond the longitudinal linear edge members to define an abutment with the longitudinal edges of the faceboards of an adjacent panel, a longitudinally extending cavity in which is accommodated a fire retardant insulating material extending along said cavity, thus providing a heat insulated fire resistant joint between the adjacent longitudinal edges of the panels.
