Safe Work Practices
HardieFire™ Insulation
Storage and HandlingStore in an internal dry area, out of direct sunlight and not exposed to chemicals. It must not be installed during an electrical storm and it must be installed in a dry state to a dry surface and protected from weather during transport and storage. HardieFire™ insulation has not been designed to withstand prolonged direct exposure to the exterior elements. Ensure that the insulation is completely dry prior to lining.
Protective EquipmentKeep exposure to a minimum and minimise quantities kept in work areas. Avoid contact with eyes. When handling and installing Hardiefire™ insulation, to prevent irritation ensure you wear:• Safety goggles/glasses conforming to AS/NZS 1336,• Protective clothing such as gloves and long sleeve
shirts and trousers,• P1 or P2 respirators.
Before Installation• You must turn the mains power ‘Off’ before entering
work space. If in doubt, you must consult a licensed electrician.
• Care and safety measures must be followed when working in areas that contain live electrical wiring.
• Defective electrical cables, terminals or any other electrical wiring must be repaired by the relevant specialist prior to installation.
• Ensure workspace has adequate and ample ventilation. If working in confined spaces, it is recommended to use a HEPA vacuum or other suitable dust extractors.
• Before entering workspace, complete a risk assessment inspection to identify hazards including but not limited to electrical, site access and ventilation.
CuttingIt is recommended to cut outdoors. If cutting indoors, please ensure that workspace is properly ventilated or HEPA vacuums/dust extractors are used.1. Position cutting station so wind will blow dust away
from the user or others in working area.2. Use either hand saw or reciprocating saw.
DisposalDiscard any waste pieces of HardieFire™ insulation in accordance with your local council guidelines. Dispose of the material in such a manner to prevent exposure and escape.
Further Health and Safety InformationFor more information refer to the HardieFire™ insulation SDS available at jameshardie.com.au and accel.com.au.
James Hardie™ products contain sand, a source of respirable crystalline silica which is considered by some international authorities 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. During installation or handling, ensure to follow James Hardie's Best Practice Book and SDS for James Hardie™ fibre cement products and HardieFire™ insulation available at jameshardie.com.au.

Design Considerations
Slab and FootingsThe slab and footings on which the building sits must comply with AS 2870 ‘Residential Slabs and Footings – Construction’ and the requirements of the NCC.
Boundary SetbackJames Hardie recommends a minimum setback of 500mm from an existing structure. This is to allow for maintenance of the selected external cladding as per the respective installation instructions. For systems built right against an existing structure, please refer to the HardieSmart™ ZEROLOT™ Design Guide.
Please note that council, state or other regulations may apply in your development which specify different setbacks, height, width and other design criteria. Additionally, confirmation in writing in the form of a statutory declaration from the registered owner of the adjoining premises may be required to demonstrate compliance. The designer or specifier must ensure that the system is fit for purpose and complies with the relevant requirements and regulations.
Bracing Performance
Thermal PerformanceThis guide outlines certified modelled Total R-values for HardieSmart™ Wall Systems. Use this information to assist in satisfying the minimum deemed to satisfy NCC thermal resistance requirements and in verification software tools.
The Total R-value is based on using HardieWrap™ weather barrier with an emissivity of 0.16W/m2. The Total R-values for common systems are in accordance with AS4859.1:2002 including Amendment 1:2006 'Materials for Thermal Insulation of Buildings'.
This guide must be read in conjunction with the James Hardie Structural Bracing Application Guide (designed in accordance with AS 1684 'Residential Timber Framed Construction'). The James Hardie Structural Bracing Application Guide contains fixing details and bracing capacity for James Hardie™ sheet bracing and other fibre cement cladding. All design capacities quoted are Ultimate Limit State (ULS) figures and have been certified by consulting engineers, Cardno (NSW). Pty Ltd.
All design and construction must comply with the appropriate requirements of the National Construction Code (NCC) and other applicable regulations and standards. The specifier or other party responsible for the project must ensure that the details in this specification are appropriate for the intended application and that additional detailing is performed for specific design or any areas that fall outside the scope of this specification.
General
The HardieSmart™ Boundary Wall System has been designed and tested in accordance with P2.2.2 as per NCC requirements. For any variations, it is the responsibility of the designer or specifier to identify moisture related risks associated with any particular building design. Wall construction design must effectively manage moisture, accounting for both the interior and exterior environments of the building, particularly in buildings that have a higher risk of wind driven rain penetration or that are artificially heated or cooled. All wall openings, penetrations, intersections, connections, window sills, heads and jambs must be flashed prior to cladding installation.
Weather Resistance
In areas within 1km of a coastal area, areas subject to salt spray and other corrosive environments, class 4 fasteners must be used. All other areas require a minimum class 3 fastener. Fasteners must be fully compatible with all other materials that they are in contact with to ensure the durability and integrity of the assembly. Contact the fastener manufacturer for more information.
Coastal Areas
James Hardie™ fibre cement products and components such as HardieFire™ insulation and HardieWrap™ weather barrier must be as specified in the system.
No statement of performance will be provided by James Hardie when alternative products are used.
Component Substitution
Fire ResistanceNCC Vol. 2 Section 3.7.1.8 requires boundary walls to maintain an FRL of 60/60/60 minutes. HardieSmart™ Systems have been certified by the CSIRO Division of Building Construction and Engineering and the Building Research Association of New Zealand (BRANZ) in accordance with the principles of AS1530.4 (FCO-3222). They are suitable to achieve 60/60/60 FRL when designed in accordance with this guide.
Fastener TypeBrad nail and/or adhesive fixings are not recommended in fire and acoustic-rated systems. Please refer to the respective product for alternative fixing methods.

Framing
Material Seasoned timber only. Timber used for house construction must have the level of durability appropriate for the relevant climate and expected service life. Reference AS1684.2 ‘Residential Timber Framed Construction’.
Stud Size
90x45mm recommended. 90x35mm may be used; however, check your selected James Hardie™ external cladding product for additional requirements.
Stud Spacing
600mm maximum. Check whether you require closer stud spacings for your site wind pressures and tile weight (only for tiled walls). It must be noted that HardieFire™ insulation sizes have been optimised for 45mm studs at 600mm centres and 35mm studs at 450mm centres, cutting may be required otherwise.
Maximum Nogging Spacing
1200mm
Structural Capacity
5 kN/stud. The load bearing capacities of the timber-framed walls must be in accordance with AS1684 ‘Residential Timber-Framed Construction’ and AS1720.1 ‘Timber Structures’.3.4 kN/stud.For 90x35mm studs spaced at 600mm centres. Please note that if specifying 600mm centres, cutting of HardieFire™ insulation will be required as sizes have been optimised for 45mm studs at 600mm centres.
Stud Height (mm)
Stud Size Max. Height
90x35mm 3000mm
90x45mm 3600mm
90x70mm 3900mm
90x90mm 4200mm
Tolerance Ensure frame is square and work from a central datum line. Frames must be straight and true to provide a flush face to receive the sheeting. A suggested maximum tolerance of between 3mm and 4mm in any 3000mm length will give best results.
Services and Fixtures
Electrical Electrical cables may be run in the service cavity or via a PVC conduit not exceeding 20mm in diameter. Refer to Figures 16-17.
Plumbing Plumbing pipes with a diameter less than 20mm may be run in the service cavity (see Figures 19-21). For larger pipes, they must be relocated to non fire-rated partitions.
Wall Fixtures
When fixing brackets, cabinets, shelves, or any other fixture that requires the wall to carry a load, they must be fixed to the framing member (i.e. studs) and must not rely solely on the lining.
Air- Conditioning
Pipes with an outside diameter less than 20mm and carrying non-flammable refrigerants may be run inside the service cavity (see Figures 22-23).
HardieWrap™ Weather Barrier
Refer to HardieWrap™ weather barrier datasheet for more information on the standard installation.
HardieFire™ Insulation
Must be used as the frame cavity infill and must be compressed 5mm minimum in both vertical and horizontal directions (i.e. batt size must be at a minimum 5mm wider and longer than frame stud bay). Ensure there are no gaps in the installation and position batts hard against external wall face to allow for an internal service cavity. Please refer to HardieFire™ insulation datasheet at jameshardie.com.au
Villaboard™ Lining
Must be installed in accordance with the current Villaboard™ lining installation instructions. Alternative James Hardie™ internal linings with a minimum of 6mm thick may be used in lieu of Villaboard™ lining.
James Hardie™ External Cladding
Any James Hardie™ external cladding 6mm or thicker may be used. It must be installed in accordance with the respective installation instructions.
Others For other components not supplied by James Hardie ensure to follow the instructions set out in this guide and the respective manufacturer's recommendations.
Services are recommended to be installed after HardieFire™ insulation has been fitted in the stud bays to ensure cables and pipes are at the right depth. Services may only be run in the service cavity between the insulation and the lining (i.e. must not exceed 20mm deep). WARNING: When fixing lining, avoid nailing near pipes or cables as it may cause damage.
Component Installation
Running Services by Notching or Drilling of the Timber Frame: When notching or drilling studs or plates, provided these are structural, limitations apply in accordance with AS1684.2. Typically stud penetrations are limited to a maximum 20mm drill hole, located 10mm from the stud edge. Refer to Figure 15 for further information.
