TABLE NOTES:
* For increased heights, stud size may need to be increased. Where the height of an external wall exceeds 3.3m, the stud size must be increased to meet fire resistance requirements
# Stud spacing is based on a load bearing capacity of 5 kN/stud. The stud spacing may be reduced in accordance to wind pressure installation requirements for the selected external cladding product, please refer to the relevant and respective literature for more information. The loadbearing capacities of the timber-framed walls must be determined in accordance with AS1684 ‘Residential timber-framed construction’ and AS1720.1 ‘Timber structures’
† Thermal value is based on using a single reflective vapour permeable membrane (e.g. HardieWrap™ weather barrier) with an emissivity of 0.16. The total R-values for common systems are in accordance with AS4859.1:2002 and Amendment 1:2006 Materials for Thermal Insulation of Buildings. Note that the R-value will be reduced in cavities that are ventilated.
^ Additional fastener and design considerations may be required. Refer to James Hardie Structural Bracing Application guide for more information.~ Stud spacing may be increased to 600mm centres with a reduced loadbearing capacity of 3.4 kN/stud. Please note that if specifying 600mm centres, cutting of
HardieFire™ Insulation will be required as sizes have been optimised for 45mm studs at 600mm and 35mm studs at 450mm centres. It is recommended to install 560mm batts horizontally to minimise cutting. Ensure a 5mm compression throughout and no gaps.
^^ A larger minimum timber stud size may be required, Please refer to framing section under design considerations.** When an acoustic rating of Rw+Ctr of 46 or less is required, 6mm Villaboard® lining may be used in lieu of 9mm Villaboard® lining.

James Hardie recommends the following products for use in conjunction with HardieSmart™ Systems. James Hardie does not supply these products. Please contact the component manufacturer for information on their warranties and further information on their products.
Fire and Acoustically rated sealant: Suitable and tested sealant for fire- and acoustically-rated construction and HardieSmart™ Systems. Used to fill control joints, penetrations and any wall gaps to maintain acoustic and fire integrity. The sealant may need to be water resistant if required in a wet area.
Reciprocating Saw or Hand Saw: Used to cut HardieFIre™ Insulation when required. Refer to safety and handling section.
Fire Resisting Mineral Wool: Used to maintain FRL of the selected wall system at junctions where relevant. Please see construction details for applications. It must be installed in accordance with manufacturer recommendations.
PAGE 2 OF 8 | HARDIESMART™ INTERTENANCY WALLS – DESIGN GUIDE
SYSTEM PERFORMANCE1. FIRE RESISTANCE LEVEL (FRL): The fire resistance level (FRL) test
reports and Letters of Opinion in this guide have been certified by the CSIRO Division of Building Construction and Engineering and the Building Research Association of New Zealand (BRANZ).
Fire resistance testing to determine the FRL of a wall (in the form of a specimen) has been conducted to the Australian Standard AS 1530 Part 4: ‘Fire Resistance Tests of Elements of Building Construction’. The standard follows the basic principles and provisions contained in ISO-834 ‘Fire Resistance Tests – Elements of Building Construction’. For more information on fire performance in buildings, please refer to James Hardie Fire and Acoustically rated walls Application Guide.
2. ACOUSTIC PERFORMANCE: The acoustic test reports in this manual have been certified by the RMIT. Systems used in building construction are tested under laboratory conditions to establish their sound insulation characteristics. The method of measurement is described in AS1191 ‘Acoustics – method for laboratory measurement of airborne sound transmission loss of building partitions’. 3.5.2 Acoustic modelling. Based on the test results indicated above, acoustic modelling for HardieSmart™ wall systems was undertaken by SLR Acoustics Pty Ltd. For more information on acoustic performance in buildings, please refer to James Hardie Fire and Acoustically rated walls Application Guide.
3. THERMAL PERFORMANCE: This guide outlines a range of certified modelled total R-values for HardieSmart™ wall systems. This information will assist in both satisfying the minimum deemed to satisfy Building Code of Australia (BCA) thermal resistance requirements or used with verification software tools across Australia..
4. BRACING PERFORMANCE: To achieve the necessary bracing requirements, this guide must be read in conjunction with James Hardie Structural Bracing Application Guide. It has been designed in accordance with AS 1684 ‘Residential Timber Framed Construction’ (‘the code’), and gives fixing details and bracing capacity for James Hardie products. All design capacities quoted are Ultimate Limit State (ULS) figures and have been certified by consulting engineers, Cardno (NSW) Pty Ltd.
DESIGN CONSIDERATIONS1. INTERNAL LINING: Villaboard® lining (9mm in thickness) is recommended
when using and specifying HardieSmart™ Intertenancy wall system. Villaboard® lining may be replaced by Versilux® lining (9mm).
NOTES: If Architectural™ Invibe or Inraw™ panels are used, 6mm Villaboard® lining must be fixed behind these panels to maintain fire rating. Villaboard lining must be fixed in accordance with the installation guide current at the time of installation.
2. HARDIEFIRE™ INSULATION: It must be used as the frame cavity infill designed to be compressed 5mm or more in both vertical and horizontal directions (I.e. Batt size are cut 5mm wider and longer than frame stud bay). Ensure there are no gaps in the installation. Please refer to figure 1 for more information on installation. If cutting is required, it is recommended to cut outdoors. If indoors, please ensure that workspace is properly ventilated or HEPA vacuums/dust extractors are used.
a. Position cutting station so wind will blow dust away from the user or others in working area.
b. Use one of the following methods based on the required cutting rate: i. Reciprocating Saw ii. Mechanical Hand Saw
3. FRAMING:
■ Material type: Dry 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’. Steel frames are not suitable.
■ Minimum stud width: Studs that are 35mm in width may be used in accordance to system information section; however, depending on the James Hardie external cladding and internal lining product selected, where sheet jointing is required; the minimum stud width may be 38mm so as to properly accommodate the joint.
■ Stud spacing: 600mm maximum. Check whether the selected external cladding and/or internal lining require closer stud spacing 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 and 35mm studs at 450mm centres, cutting may be required otherwise.
■ Nogging: 1350mm maximum centres.
4. SLAB AND FOOTINGS: The slab and footings on which the building is situated must comply with AS 2870 ‘Residential slabs and footings – Construction’ and the requirements of the Building Code of Australia (BCA).
5. FIRE AND ACOUSTICALLY RATED SEALANT: Fire sealant in junctions and gaps as indicated in construction details to maintain fire and acoustic integrity of the system. E.g. Bostik FireBan One.
6. FASTENER TYPE: Brad nail and/or adhesive fixing are not recommended in fire and acoustically rated systems. Please refer to the respective product for alternative fixing methods.
7. PENETRATIONS: All penetrations require careful and comprehensive treatment to maintain Fire Resistance Level (FRL) of the system; therefore, they should be avoided. Generally, dealing with penetrations in fire and acoustically rated systems can be avoided by placing them in external non-fire rated systems, or by building false walls or box/bulkheads, creating pockets in the fire rated element. For more information contact James Hardie Engineering Solutions Team on 13 11 03.
8. PAINT/TEXTURE: Refer to the respective James Hardie internal installation manual for coating requirements. Please refer to coating manufacturer for
