Attaching panel siding to wood furring:
When attaching panel siding products over wood furring, the
typical fastener used is the 6d common 2 in. long nail.
This fastener is going to be the shortest fastener approved for
fastening panel siding products into wood, therefore the furring
must be a minimum of 1-11/16 in. thick to achieve the same
values as ESR 1844, Table 4, given stud spacing, building height,
and exposure category.

It is deemed an acceptable practice to not fasten along the top
and bottom plates for the 5/16 in. HardiePanel configurations
listed in the ESR 1844, Table 4 using the following fastener type:
• 0.091 in. shank X 0.225 in. HD X 1.5 in. long ring shank nail
• Min. No. 8 X 0.311 HD X 1 in. ribbed bugle head screw
• 0.10 X 0.25 in. HD X 1.5 in. long ET&F pin or equivalent
• 6d common 2 in. long nail
Conditions of use:
• This practice is acceptable for transverse load only.
• This practice is not acceptable for racking shear values or
in-plane forces other than perpendicular/normal wind forces.
• All vertical joints shall occur over framing.
• All other James Hardie Installation Requirements shall be
followed.
Attaching panel siding to steel furring:
When attaching panel siding products to metal furring, the steel
furring must be a minimum 20 gauge steel. A fastener should be
chosen out of the ESR 1844, Table 4, which is approved for
attaching to steel framing. Two general rules that should be
considered when choosing a fastener is that a nail (pin) must
penetrate steel furring ¼ in., and screws must penetrate steel furring
3 full threads. Therefore, if the rules for steel fastening are followed
– given stud spacing, building height, and exposure category – the
values are the same as ESR 1844, Table 4 states for the chosen
fastener.
