An insulated roof deck system which can be used in installing metal roofs is set forth. The system includes a plurality of metal purlins (10), a plurality of metal roof panels (2), a plurality of thermal insulation blocks (4), cleats (14), and threaded fasteners (12). The metal purlins (10) can form a parallel array of purlins. The metal roof panels (2) can be attached to the metal purlins (10) in the parallel array. The thermal insulation blocks (4) can be disposed between the metal purlin (10) and the metal roof panel (2). The cleat (14) can be disposed between the thermal insulation blocks (4) and the metal roof panel (2) and has a protrusion which is capable of securing the thermal insulation block (4) and inhibits lateral movement between the thermal insulation block (4) and the cleat (14). The threaded fastener (12) secures the metal roof panel (2), the cleat (14), and the thermal insulation block (4) to the metal purlin (10). The threaded fastener (12) can include one or more unthreaded regions sufficient to reduce or prevent over-tightening during use. |
