(54) Roof constructions


(57) A roof construction comprises a purlin 1; internal liner sheet 2 having a plurality of load-carrying flattened peaks and valleys 6 and 7, fixed directly to the purlin 1; elongate metal space element 3 with expanded-slit perforations 10 fixed directly to the liner sheet 2 at right-angles to the purlins; and an external weather layer 4 fixed directly as a metal-to-metal connection to the top of spacer element 3. This construction provides the advantages of secure metal-to-metal fixing throughout together with surprisingly low thermal conductivity due to the perforations 10 and the configuration of sheet 2.
