ABSTRACT:
A fastening assembly for use in fastening a thick insulating layer 8, typically between 130 and 300 mm, onto a roof decking 9 comprises a self drilling and self tapping screw-threaded fastener 1 having a driving head 11; a load distributing plate 2 for engaging the upper surface of the insulation material 8 to hold it and distribute the fastening load so that the fastening assembly does not pull through the insulation material; and, an extensible resilient member 3 having one end 6 coupled to the head of the screw-threaded fastener 1 and the other end coupled to the load distributing plate 2. At least one coupling permit the screw-threaded fastener 1 to rotate with respect to the load distributing plate 2 to allow the fastener 1 to be driven through and screwed into the roof decking 9 to fasten the insulation material 8. The provision of a resilient element 3 accommodates minor variations in the manufacture of the insulation material, and distortions and deformations of it that occur in use. The resilient element 3 also accommodates any lateral movement of the load-distributing plate and the screw-threaded fastener caused by, for example, thermal expansion and contraction or settlement of the building.
