panels may be installed over either steel or wood framing complying with the local building code. See general fastener requirements. Install soffits to
nominal 2 x 4 framing members spaced a maximum of 24 inches on center (fig.4),
• All edges must be supported by framing. (figs. 3 & 4)
• Install water barriers and air barriers as required by local building codes. James Hardie will assume no responsibility for moisture infiltration.
• Ensure gutters have end caps. Maintain a minimum 1" gap between end caps and siding & trim (fig.5).
• Install kickout flashing at roof-wall junctions. (fig 6.)
• DO NOT use stain on James Hardie

products.
GENERAL REQUIREMENTS:
INSTALLATION:
• HardieSoffit panels must be fastened to a solid, nailable substrate such as a wood 2x subfascia.
• Additional framing may be needed to ensure proper fastening.
• Soffits can be installed as shown in figure 1. Position the vent holes toward the outside of the eave
for optimal airflow.
• 12" to 24" wide Vented HardieSoffit panels, provide 5.0 square inches of net free ventilation per
lineal foot.
• Alternatively vents can be installed into non-vented soffit.
• If necessary, an insect screen can be installed using construction adhesive.
Note: net free ventilation will be reduced.
Fastener Requirements
• Position fasteners 3/8" from panel edges and no closer than 2" away from corners when using
soffit greater than 12" wide (fig. 4) and no closer than 1" away from corners when using soffit that is
less than or equal to 12" wide (fig. 3).
Jointing Methods
• Install panels in moderate contact at ends, provide PVC or metal jointers, battens or leave
appropriate gap and caulk (fig 2).

products contain respirable crystalline silica, which is known to the State of California to cause cancer and is considered by IARC and NIOSH to be a cause of cancer from some occupational
sources. Breathing excessive amounts of respirable silica dust can also cause a disabling and potentially fatal lung disease called silicosis, and has been linked with other diseases. Some studies suggest
smoking may increase these risks. During installation or handling: (1) work in outdoor areas with ample ventilation; (2) use fiber cement shears for cutting or, where not feasible, use a HardieBlade saw
blade and dust-reducing circular saw attached to a HEPA vacuum; (3) warn others in the immediate area; (4) wear a properly-fitted, NIOSH-approved dust mask or respirator (e.g. N-95) in accordance with
applicable government regulations and manufacturer instructions to further limit respirable silica exposures. During clean-up, use HEPA vacuums or wet cleanup methods - never dry sweep. For further
information, refer to our installation instructions and Material Safety Data Sheet available at www.jameshardie.com or by calling 1-800-9HARDIE (1-800-942-7343). FAILURE TO ADHERE TO OUR
WARNINGS, MSDS, AND INSTALLATION INSTRUCTIONS MAY LEAD TO SERIOUS PERSONAL INJURY OR DEATH.

OUTDOORS
1. Position cutting station so that wind will blow dust away from user
and others in working area.
2. Use one of the following methods:
a. Best: i. Score and snap
ii. Shears (manual, electric or pneumatic)
b. Better: i. Dust reducing circular saw equipped with a
HardieBlade
®
saw blade and HEPA vacuum extraction
c. Good: i. Dust reducing circular saw with a HardieBlade saw blade
(only use for low to moderate cutting)
INDOORS
1. Cut only using score and snap, or shears (manual, electric or pneumatic).
2. Position cutting station in well-ventilated area
- NEVER use a power saw indoors
- NEVER use a circular saw blade that does not carry the HardieBlade saw blade trademark
- NEVER dry sweep – Use wet suppression or HEPA Vacuum
Important Note: For maximum protection (lowest respirable dust production), James Hardie recommends always using “Best”-level cutting methods where feasible.
NIOSH-approved respirators can be used in conjunction with above cutting practices to further reduce dust exposures. Additional exposure information is available
at www.jameshardie.com to help you determine the most appropriate cutting method for your job requirements. If concern still exists about exposure levels or you
do not comply with the above practices, you should always consult a qualified industrial hygienist or contact James Hardie for further information.
