About Prominence™
With its elegant flat pans and ease of installation the profile is a rare mix that both the specifier and the builder can appreciate. Available in a 265mm and a 465mm wide panel. As with all the profiles in the Fielders® Finesse® range,
Fielders® Prominence™ is available in any colour you choose and looks particularly striking in a Metallic COLORBOND®. Prominence™ is also available in 0.75mm steel and 1.00mm aluminium (subject to minimum order quantities). Contact your local Fielders® representative for availability and further information.
Prominence™ is offered on traditional supporting substrates, plywood and fibre cement panels, and now with comprehensive testing can be offered on cost effective steel battens.

Installation
Prominence™ is concealed pierce-fixed to either plywood or batten supports. This means the fastener screws pass through the sheeting at the concealed underlap edge. Screws can be placed either through the slotted holes or directly through the sheet. Where screws are placed directly through the sheet a 6mm hole should be pre- drilled to mimic the slotted holes and allow for thermal movement. See Figures PR ID NC 003-007.

Installation Details: Typical Panel Turndown
- Panels requiring field hemmed ends should be fabricated 25mm longer than the finished panel length. Valley conditions must be field cut to the appropriate angle.
- Cut back panel joints 25mm.
- Place protruding pan into the panel hemming tool. The front edge of the tool must rest against the notched joint legs on both sides.
- While maintaining pressure against the panel joints, rotate the hemming tool as close to 90° as possible.
Installation Details: Typical Stop End
- Place pan into the panel stop end tool. The front edge of the tool must rest between the ribs.
- While maintaining pressure against the panel, rotate the stop end tool as close to 90° as possible.
- Inspect completed bend.
Oil Canning
Oil canning is a characteristic of thin gauge cold formed metal products which is caused by internal stresses within the metal. There are many factors that influence the degree of oil canning and more information can be found here.
To assist in minimising the effects of oil canning in Prominence™ it is recommended that panel lengths are kept to under 9m. If longer lengths are required please discuss with Fielders.
For further information about Oil Canning, please refer to our Oil Canning reference page.
Insulation
Care needs to be taken when installing insulation with roof sheeting. When insulation thickness up to 50mm are installed the screws may need to be increased depending on the thickness and density of the insulation. When the screw is properly tightened into metal there should be a minimum of three (3) threads protruding past the support being fixed in to. For timber the screw must penetrate the timber.
When insulation is required in conjunction with Finesse® profiles, Fielders® recommend the use of a thermal spacer to help maintain Rw values as well as minimising any bulging in the the profile caused by the insulation.
Insulation blankets and batts can cause wide flat pan cladding to bow out between the supports, between fasteners along the support, or bow the pans. For insulation blankets and batts as well as more dense glass wool and rock wool, and thicker insulation, spacers are recommended.
