FireCrunch Australasia warrant the board only when the correct screws and system manuals are adhered to. (See Recommended Products).
Screw Fixing
Steel frame: For screwing FireCrunch panels to steel framing, we recommend using ribbed head bugle self countersinking screws available from all major hardware stores.
Timber frame: For screwing FireCrunch panels to wood framing we recommend using stainless steel (or suitably corrosion protected) 8-10 Countersinking Ribbed Head Class 2 / 3 screws (depending on timber hardness).
