INSTALLATION:
Fastener Joint Treatment
Position fasteners 3/8 in from panel edges and no closer than 2 in away from corners. Do not nail into corners.
• HardiePanel vertical siding must be joined on stud.
• Double stud may be required to maintain minimum edge nailing distances.
• When screws are used to attach panels to steel studs/furring,
the screws shall have wing tips. If screws do not have wing tips,
then pre-drilling is required. (Not applicable when using pins)
Follow chart below for pre-drilling:
• Vertical Joints - Install panels in moderate contact (fig. 1),
alternatively joints may also be covered with battens, PVC
or metal jointers or caulked (Not applicable to ColorPlus
®
Finish) (fig. 2).
• Horizontal Joints - Provide Z-flashing at all horizontal
joints (fig. 3).
