Cadence® Cyclonic

Western Sydney Airport Cadence

About Cadence®

With its elegant flat pans and ease of installation, Fielders Cadence® offers all of the aesthetic benefits of Fielders Prominence™ with additional structural capacities due to the clever concealed fix bracket fixings. These brackets enhance the profile's ability to deal with thermal expansion and contraction. Fielders Cadence® is available in a 265mm and a 465mm wide panel.

As with all the profiles in the Fielders Finesse® range, Fielders Cadence® is available in any COLORBOND® steel colour you choose and looks particularly striking in a Metallic COLORBOND® steel. Cadence® is also available in 0.75mm steel and 0.9mm aluminium (subject to minimum order quantities). Contact your local Fielders representative for availability and further information.

Fielders Cadence® is suitable for installation on traditional supporting substrates such as plywood and fibre cement panels, and now with comprehensive testing, can be offered on cost effective steel battens.

Cyclonic Testing

Fielders® have undertaken cyclonic testing of the Cadence® profile in a 265mm panel width for both roofing and walling applications in accordance with the Low-High Low (LHL) cyclonic testing method in the National Construction Code (NCC) and AS4040.

Design data provided for Prominence™ is based on the following Australian Standards:

  • AS1170.2:2011 Structural design actions Part 2: Wind actions
  • AS1562.1-1992 (R2016) Design and installation of sheet roof and wall cladding Part 1: Metal
  • AS4040.0-1992 Methods of testing sheet roof and wall cladding Part 0: Introduction, list of methods and general requirements
  • AS4040.1-1992 Methods of testing sheet roof and wall cladding Method 1: Resistance concentrated loads
  • AS4040.2-1992 Methods of testing sheet roof and wall cladding Method 2: Resistance to wind pressures for non-cyclone regions
  • AS4040.3-1992 Methods of testing sheet roof and wall cladding Method 3: Resistance to wind pressures for cyclone regions
  • AS4055:2012 Wind Loads for Housing

SA HB 39: 2015 Handbook - Installation code for metal roof and wall cladding National Construction Code of Australia.

Cadence® can be supported on one of three supporting structures; plywood, steel battens or Fielders® KingFlor® KF40. The cyclonic wind load capacities are shown in Table CD C WC 001.

Cyclonic Impact Resistance from Wind-Borne Debris

Parts of a building envelope (cladding, doors, windows) may be required to resist windborne debris according to AS/NZS 1170.2: 2011 and Technical Note No. 4, ‘Simulated windborne debris impact testing of building envelope components’, Cyclone Testing Station, James Cook University. These standards specify debris impact loading by timber member of 4kg mass with nominal cross-section of 100mm x 50mm and 8mm diameter spherical steel balls. Cadence® (roofing and walling), cyclonic assemblies have been evaluated to effectively resist cyclonic wind-borne debris for wind region C and D when used in conjunction with plywood or KF40® 0.75mm BMT backing for walling applications. Please refer to the relevant fixing requirements for Cadence®.

Cyclonic Fixing to KF40® Substrate

Vertical Panels

Where resistance to wind-borne debris is required as per AS/NZS 1170.2: 2011, KF40® backing is required as per the following details:
