2 Safe Working Practices 3 Design ConsiderationsWARNING - DO NOT BREATHE DUST AND CUTONLY IN WELL VENTILATED AREAJames Hardie products contain sand, a source of respirable crystalline silica.May cause cancer if dust from product is inhaled. Causes damage tolungs and respiratory system through prolonged or repeated inhalationof dust from product. Intact fibre cement products are not expectedto result in any adverse toxic effects. The hazard associated with fibrecement arises from the respirable crystalline silica present in dust generatedby activities such as cutting, rebating, drilling, routing, sawing, crushing,or otherwise abrading fibre cement, and when cleaning up, disposingof or moving dust. When doing any of these activities in a manner thatgenerates dust, follow James Hardie instructions and best practices toreduce or limit the release of dust, warn others in the area and considerrotating personnel across the cutting task to further limit respirable silicaexposure. If using a dust mask or respirator, use an AS/NZS1716 P1 filterand refer to Australian/New Zealand Standard 1715:2009 Selection, Useand Maintenance of Respiratory Protective Equipment for more extensiveguidance and more options for selecting respirators for workplaces. Forfurther information, refer to our installation instructions and Safety DataSheets available at www.jameshardie.com.au. FAILURE TO ADHERETO 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 orothers in working area.2. Warn others in the area to avoid dust.3. Consider rotating personnel across cutting tasks to further limit respirablesilica exposures.4. Use one of the following methods based on the required cutting rate:BestVillaboard knifeHand guillotineFibreshearBetter Position the cutting station in a well-ventilated area. Use adust reducing circular saw equipped with HardieBlade Saw Blade orcomparable fibre cement blade and well maintained M-class vacuum orhigher with appropriate filter for capturing fine (respirable) dust. Wear aproperly-fitted, approved dust mask or respirator (minimum P1).nnAll design and construction must comply with the appropriaterequirements of the current National Construction Code (NCC) and otherapplicable regulations and standards.Slab and FootingsThe slab and footings on which the building is situated must comply withAS 2870 ‘Residential slabs and footings – Construction’ and therequirements of the NCC.Ground ClearancesInstall James Hardie external cladding with a minimum 150mmclearance to the earth on the exterior of the building or in accordancewith local building codes if greater than 150mm is required. Maintain aminimum 50mm clearance between James Hardie external claddingand roofs, decks, paths, steps and driveways.Adjacent finished grade must slope away from the building in accordancewith local building codes, typically a minimum slope of 50mm over thefirst metre.Do not install external cladding such that it may remain in contact withstanding water.NOTEGreater clearance may be required in order to comply with termiteprotection provisions, see below for more information.Termite ProtectionThe NCC specifies the requirements for termite barriers. Where theexposed slab edge is used as part of the termite barrier system, aminimum of 75mm of the exposed slab edge must be visible to permitready detection of termite entry.nnCUTTING INDOORSCut only using VillaboardTM knife, hand guillotine or fibreshears(manual, electric or pneumatic).Position cutting station in a well-ventilated area.nnDRILLING/OTHER MACHININGWhen drilling or machining you should always wear a P1 dust mask andwarn others in the immediate area.IMPORTANT NOTES1. For maximum protection (lowest respirable dust production) James Hardierecommends always using 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 sawbladespecifically designed to minimise dust creation when cutting fibrecement- preferably a sawblade that carries the HardieBlade logo or one with atleast equivalent performance - connected to a M class or higher vacuum.4. NEVER dry sweep - Use wet suppression, or an M class vacuum orhigher 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 higherStructural BracingEasyLap and EasyTex panels can be installed to provide wall bracingagainst lateral forces due to wind. For further information, Ask James Hardieon 13 11 03.Fire Rated WallsEasyLap and EasyTex panels can achieve fire ratings of 60/60/60and 90/90/90 when constructed with additional fire rated linings asspecified in James Hardie’s Fire and Acoustically Rated Design Manual andConstruction of Fire and Acoustically Rated Walls Technical Specification.The length of fasteners must be increased for the additional linings.Moisture ManagementIt is the responsibility of designer or specifier to identify moisture related risksassociated with any particular building design. Wall construction design musteffectively manage moisture, accounting for both the interior and exteriorenvironments of the building, particularly in buildings that have a higher risk ofwind driven rain penetration or that are artificially heated or cooled.In addition, all wall openings, penetrations, junctions, connections,window sills, heads and jambs must incorporate appropriate flashing andwaterproofing. Materials, components and their installation that are usedto manage moisture in framed wall construction must, at a minimum,comply with the requirements of relevant standards and the NCC.DUST MASKS AND RESPIRATORSAs a minimum, an AS/NZS1716 P1 respirator must be used when doingany activity that may create dust. For more extensive guidance andoptions for selecting respirators for workplaces please refer to Australian/New Zealand Standard 1715:2009 “Selection, Use and Maintenanceof Respiratory Protective Equipment”. P1 respirators should be used inconjunction with the above cutting 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 you donot comply with the above practices, you should always consult a qualifiedindustrial hygienist or contact James Hardie for further information.STORAGE AND HANDLINGTo avoid damage, all 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 avoidexposure to water, moisture, etc.EASYLAP AND EASYTEX PANEL INSTALLATION GUIDE PAGE 3 OF 16
FRAMINGWeather BarrierA suitable water control membrane must be installed under JamesHardie cladding in accordance with the AS/NZS 4200.2 ‘Pliable buildingmembranes and underlays – Installation’ and NCC requirements.GeneralEasylap & Easytex panels are installed vertically either directly fixedto frame or installed to vertically oriented Scyon Cavity Trim to providea vented cavity, this can be done over either timber or steel frames. Thegeneral framing requirements for installation are given in Table 2.James Hardie has tested and certified the use of HardieWrap weather barrierfor Climate Zones 2-8 within Australia. HardieWrap weather barrier is a Class4 vapour permeable membrane that delivers a triple-shield of protection to helpagainst external weather penetration, internal condensation management andexternal heat penetration through its safe-glare reflective layer.Maximum stud, Scyon Cavity Trim and fastener spacing for EasyLap and EasyTex panels for wind load classifications of AS 4055 ‘WindLoads for Housing’ are given in Table 3.If using an alternate product in lieu of HardieWrap weather barrier orthe project is located in a hot, humid area (Climate Zone 1), the designermust ensure that the product is fit for purpose and it has the followingclassification in accordance with AS/NZS 4200.1:2017 ‘Pliable buildingmembranes and underlays – Materials’:FASTENERSGeneralAll nails must be driven flush. Before fixing to steel frame, ensure theaesthetic finish of EasyTex panels when using HardieDrive screwsis of acceptable quality prior to installation, see Important Note 3 onpage 2 of this guide. Brad nails are recommended for best aestheticfinish. For more information and advice, Ask James Hardie on 13 11 03.TABLE 1Weather Barrier ClassificationClimate ZoneWater Control Classification2-8Vapour Control Category1Fastener Durability (Including Coastal Areas)Fasteners must have the appropriate level of durability and be fullycompatible with all other materials required for the intended project. Inareas within 1km of a coastal area, areas subject to salt spray and othercorrosive environments, class 4 fasteners must be used.Vapour Permeable (Class 3 or 4)Water BarrierVapour Barrier (Class 1 or 2)Soft compressible insulation installed between the front of the wall studsand directly behind the external cladding can cause installation issues andis thus not recommended.*Cover screw hole withepoxy (e.g. Megapoxy P1.Where the temperature isbelow 15º, use Hilti CA 273)levelled flush with the panel.Once cured, apply JamesHardie Base Coat usingthe base coat applicator.Megapoxy is notrecommended for use withEasyTexTM. Refer to finishingsection for more information.FlashingAll wall openings, penetrations, intersections, connections, window sills,heads and jambs must be flashed prior to cladding installation.CountersinkScrew 2-3mm*NAIL FASTENER DEPTHTABLE 2General Framing RequirementsTypeTimberSteelDesignUse of timber framing must be in accordance with AS1684 and the framing manufacturer’s specificationsUse of steel framing must be in accordance with NASH standard for Residential and LowRise Steel Framing Part 1: Design Criteria and the framing manufacturer’s specifications.Durability‘Timber used for house construction must have the level ofdurability appropriate for the relevant climate and expectedservice life.
