TABLE NOTES:* For increased heights, stud size may need to be increased. Please refer to James Hardie Fire and Acoustically Rated Walls Application Guide for more information. # Stud spacing is based on a load bearing capacity of 5 kN/stud. The stud spacing may need to be reduced in accordance with 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.

** HardieSmart™ ZeroLot wall system consists of two external boundary walls with minimum offset and construction is commonly staged; therefore, acoustic requirements and above performance values are only measured for each external wall.

^ 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. 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.

Designed for buildings where external walls are in close proximity to the boundary as well as all bushfire zoned areas that require a Fire Resistance Level (FRL) of up to 1 hour. This integrated solution will not only satisfy fire requirements but will also provide you with excellent acoustic, energy efficiency and bracing performance.

Please see the design considerations section for suitable James Hardie external cladding and lining products.

5. FRAMING:

■ Material type: Dry seasoned dry 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 45mm 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.

6. 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).

7. GROUND CLEARANCES: Install James Hardie external cladding with a minimum 150mm clearance to the earth on the exterior of the building or in accordance with local building codes if greater than 150mm is required. Maintain a minimum 50mm clearance between James Hardie external cladding and roofs, decks, paths, steps and driveways.

8. TERMITE PROTECTION: The BCA specifies the requirements for termite barriers; please refer to third party companies for suitable termite barrier mechanisms. Where the exposed slab edge is used as part of the termite barrier system, a minimum of 75mm of the exposed slab edge must be visible to permit ready detection of termite entry. Adjacent finished grade must slope away from the building in accordance with local building codes, typically a minimum slope of 50mm minimum over the first metre.

Do not install external cladding such that it may remain in contact with standing water.

HARDIESMART™ BOUNDARY AND ZEROLOT WALLS – DESIGN GUIDE | PAGE 3 OF 8

9. FIRE AND ACOUSTICALLY RATED SEALANT: Use a tested and warranted 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.

10. FASTENER TYPE: Brad nail and/or adhesive fixing are NOT recommended in fire and acoustically rated systems. Please refer to the respective James Hardie product for alternative fixing methods.

11. PENETRATIONS: All penetrations require careful and comprehensive treatment. They should be fire stopped, kept to a minimum, kept as small as possible and designed to cater for thermal movement and shrinkage. 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.

12. PAINT/TEXTURE: Refer to the respective James Hardie internal lining and external cladding installation manual for coating requirements. Please refer to coating manufacturer for suitability and specific requirements.

When installing Villaboard® lining in areas that are not exposed and there is no concern of aesthetics such as roof cavities, James Hardie™ Top coat and finishing coatings are not required to maintain FRL and acoustic performance. However, the joints must be sealed with an appropriate fire and acoustically rated sealant or alternatively James Hardie™ Base Coat.
