The invention provides an insulated roof lining consisting of rectangular roofing boards supported on rafters with each board consisting of a hard covering plus a loose insulation layer connected therewith plus a reinforcing body embedded in the insulation layer and firmly connected with the covering. The covering projects laterally, at two sides starting from a corner of the layer, beyond the edges of the layer and partly overlaps the adjoining roofing boards.
