1. Before InstallationAll design and construction must comply with the appropriate requirementsof the current applicable building codes, James Hardie’s instructions andspecifications and any other applicable regulations and standards current at thetime of construction. Failure to do so may lead to personal injury, affect systemperformance, violate local building codes and void James Hardie’s productwarranty. This guide contains minimum requirements, local or regulationsrequirements may be greater, please ensure to check before installation.DIAGONALSTANDARD90º 90ºThe installer must ensure the product meets the aesthetic requirements beforeinstallation. James Hardie will not be responsible for rectifying aesthetic surfacevariations following installation. The responsible party for the project must ensureFIGURE 1 LAYOUT OPTIONSthat all details in this specification are appropriate for the intended application.1.1 Substructure ConsiderationsCRITERIAMINIMUM REQUIREMENTMaterialTermite resistant timber (AS 1684) or Steel with BMTbetween 0.6-1.9mm (NASH)Joist width 45mm min. , tolerance of 3-4mm over 3m.Residential Max.

Load: 3.78 kN (point), 10 kPa (distributed)All short edges of the boards must be fully supported.Any changes in direction will require additional supporte.g. corners, use of break-a-boards, etc.All framing elements including fasteners must have theappropriate level of durability for the application includingbut not limited to termite resistance, corrosion andweather exposure. Confirm suitability with manufacturer.A minimum 150mm between ground surface and theunderside of the lowest horizontal framing member.A minimum of 50mm unobstructed clearance from thelandscape to the bottom end of the fascia or deck enclosureto allow cross flow ventilation in the sub-floor. Refer to Figure 2.- BAL-29: Timber or steel frame for enclosed decks andbushfire resisting timber or steel frame for unenclosed decks.- BAL-40: Timber or steel frame for enclosed decks andonly steel frame for unenclosed decks.- BAL-FZ: Steel frame only, HardieDeckTM Snap-in TopStrip FZ must be used, all sides must be open and a1:100 deck fall is required to allow drainage.DimensionsJoistSpacing &Loading*(See Figure 1for layouts andrefer to page6 for ilationin subfloorBushfireProne AreasRequirements1.2 Other Design ConsiderationsCRITERIAMINIMUM REQUIREMENTCorrosiveHardieDeckTM is not suitable for use in Alpine areasEnvironments (Climate zone 8) or in areas within 50m of breaking surfFor swimming pools, coastal areas (within 1 km ofshoreline) and others, particular attention must be paidto sealers and sub-floor ventilation; this includes but it isnot limited to: 10mm Control joint around pool perimeter,sealing the deck within 7 days of installation and addinganti-slip additives to the sealer specified.SlipThe slip resistance is dependant on the sealer, for moreResistanceinformation, refer to the FAQ in hardiedeck.com.auBalustrades The balustrade upright supports must be fixed to the structuralframe and not to the HardieDeck system. Allow 10mm gapfor movement and in bushfire areas ensure that the gap iscovered, sealed or backed with a non-combustible material.SealingFor recommendations, suitability and applicationinstructions refer to the HardieDeck SealingGuide available at hardiedeck.com.au/downloadHardieDeckTM must be sealed within 60 days, and within 7days if around swimming pools or within 1km of coastal areas.Fasteners- For Timber Frames: Fasteners are included withConcealed Fixing System. If face fixing is required, werecommend a Stainless steel 8 gauge type 17 50mm screw.- For Steel Frames: We do not recommend the standardfasteners. As an alternative, we recommend usingHardieDriveTM 25mm screws and the HardieDriveTM41mm long for face fixing if required. For corrosiveenvironments, HardieDriveTM is not suitable, you mustuse an equivalent class 4 screw or higher.1.3 Safe Working PracticesWARNING - DO NOT BREATHE DUST AND CUTONLY IN WELL VENTILATED AREAJames Hardie products contain sand, a source of respirable crystalline silica. May causecancer if dust from product is inhaled. Causes damage to lungs and respiratorysystem through prolonged or repeated inhalation of dust from product.Intact fibre cement products are not expected to result in any adverse toxic effects. Thehazard associated with fibre cement arises from the respirable crystalline silica present indust generated by activities such as cutting, rebating, drilling, routing, sawing, crushing, orotherwise abrading fibre cement, and when cleaning up, disposing of or moving dust.When doing any of these activities in a manner that generates dust, follow JamesHardie instructions and best practices to reduce or limit the release of dust, warnothers in the area and consider rotating personnel across the cutting task to furtherlimit respirable silica exposure.If using a dust mask or respirator, use an AS/NZS1716 P1 filter and refer toAustralian/New Zealand Standard 1715:2009 Selection, Use and Maintenance ofRespiratory Protective Equipment for more extensive guidance and more options forselecting respirators for workplaces. For further information, refer to our installationinstructions and Safety Data Sheets available at www.jameshardie.com.au. FAILURETO ADHERE TO OUR WARNINGS, SAFETY DATA SHEETS, AND INSTALLATIONINSTRUCTIONS MAY LEAD TO SERIOUS PERSONAL INJURY OR DEATH.JAMES HARDIE RECOMMENDED SAFE WORKING PRACTICESCUTTING OUTDOORS1. Position cutting station so wind will blow dust away from the user or others in working area.2. Warn others in the area to avoid dust.3. Consider rotating personnel across cutting tasks to further limit respirable silica exposures.4. Use one of the following methods based on the required cutting rate:Best n Villaboard knife n Hand guillotine n FibreshearBetter n Position the cutting station in a well-ventilated area. Use a dust reducing circularsaw equipped with HardieBlade Saw Blade or comparable fibre cement blade andwell maintained M-class vacuum or higher with appropriate filter for capturing fine(respirable) dust. Wear a properly-fitted, approved dust mask or respirator (minimum P1).CUTTING INDOORSnCut only using VillaboardTM knife, hand guillotine or fibreshears (manual, electric or pneumatic).nPosition cutting station in a well-ventilated area.DRILLING/OTHER MACHININGWhen drilling or machining you should always wear a P1 dust mask and warn others in theimmediate area.IMPORTANT NOTES1. For maximum protection (lowest respirable dust production) James Hardie recommends alwaysusing best practice cutting methods where feasible.2. NEVER use a power saw indoors or in a poorly ventilated area.3. ALWAYS use a dust reducing circular saw equipped with a sawblade specifically designed tominimise dust creation when cutting fibrecement - preferably a sawblade that carries the HardieBlade logo or one with at least equivalent performance - connected to a M class or higher vacuum.4. NEVER dry sweep - Use wet suppression, or an M class vacuum or higher with appropriate filter.5. NEVER use grinders.6. ALWAYS follow tool manufacturers’ safety recommendations.7. ALWAYS wear a properly fitted, approved dusk mask, P1 or higherDUST MASKS AND RESPIRATORSAs a minimum, an AS/NZS1716 P1 respirator must be used when doing any activity that maycreate dust. For more extensive guidance and options for selecting respirators for workplacesplease refer to Australian/New Zealand Standard 1715:2009 “Selection, Use and Maintenance ofRespiratory Protective Equipment”. P1 respirators should be used in conjunction with the abovecutting practices to minimise dust exposure. For further information, refer to Safety Data Sheet(SDS) available at www.jameshardie.com.au. If concern still exists about exposure levels or youdo not comply with the above practices, you should always consult a qualified industrial hygienistor contact James Hardie for further information.1.4 Storage and HandlingTo avoid damage, James Hardie building products should be storedwith edges and corners of the product protected from chipping. JamesHardie building products must be installed in a dry state and protectedfrom weather during transport and storage. The product must be laidflat under cover on a smooth level surface clear of the ground to avoid exposure to water and moisture
