Pierce Fixing

Fasteners must be selected to match the life expectancy of the cladding material. Recommendations from fastener manufacturers should be sought.

Only fasteners complying with AS 3566:2002 and those that are compatible with the roofing material should be used for its fastening.

Care needs to be taken when installing insulation with roof sheeting. When insulation thickness up to 50mm are installed the screws detailed in Table PF PF NC 001 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 as much as the screws detailed in Table PF PF NC 001 do without insulation.

For insulation thicknesses greater than 50mm Fielders® recommend the use of a thermal spacer to help maintain Rw values as well as minimising any bulging in the profile caused by the insulation.
