<p>Layers comprising a sealing foil on an intermediate layer are fixed on a load bearing structure by a disc assembly, in fixing insulating and sealing layers in position. The intermediate layer (2) is laid on the support structure, if necessary with a moisture barrier below (3) and a stop (4) on top. The sealing layer (1) is laid on it. A lug (14), forming part of a top disc (7) is pressed through the sealing layer, and screwed into the bottom disc, so that this layer is firmly clamped between the bearing faces (15,16) of the two discs.</p> |
