2 Safe workingpracticesWARNING - DO NOT BREATHE DUST AND CUTONLY IN WELL VENTILATED AREAJames Hardie products contain respirable crystalline silica which isconsidered by some international authorities to be a cause of cancerfrom some occupational sources. Breathing excessive amountsof respirable silica dust can also cause a disabling and potentiallyfatal lung disease called silicosis, and has been linked with otherdiseases. Some studies suggest smoking may increase these risks.During installation or handling: (1) work in outdoor areas with ampleventilation; (2) minimise dust when cutting by using either ‘Scoreand Snap’ knife, fibre cement shears or, where not feasible, use aHardieBlade Saw Blade and dust-reducing circular saw attachedto a HEPA vacuum; (3) warn others in the immediate area to avoidbreathing dust; (4) wear a properly-fitted, approved dust mask orrespirator (e.g. P1 or P2) in accordance with applicable governmentregulations and manufacturer instructions to further limit respirablesilica exposures. During clean-up, use HEPA vacuums or wetcleanup methods – never dry sweep. For further information, referto our installation instructions and Safety Data Sheets available atwww.jameshardie.co.nz.FAILURE TO ADHERE TO OUR WARNINGS, SAFETY DATASHEETS, AND INSTALLATION INSTRUCTIONS MAY LEADTO SERIOUS PERSONAL INJURY OR DEATH.James Hardie recommended safe working practicesCUTTING OUTDOORS1. Position cutting station so that wind will blow dust awayfrom user or others in working area.2. Use one of the following methods based on the requiredcutting rate:BEST• Score and snap• Hand guillotine• FibreshearBETTER• Dust reducing circular saw equipped with HardieBladeSaw Blade and HEPA vacuum extraction.GOOD• Dust reducing circular saw equipped with HardieBladeSaw BladeCUTTING INDOORS• Cut only using score and snap, hand guillotine orfibreshears (manual, electric or pneumatic).• Position cutting station in well-ventilated areasanding/rebating/DRILLING/OTHERMACHININGWhen sanding/rebating/drilling/machining you should alwayswear a P1 or P2 dust mask and warn others in the immediatearea.IMPORTANT NOTES:1. For maximum protection (lowest respirable dustproduction), James Hardie recommends always using“Best” — level cutting methods where feasible2. NEVER use a power saw indoors3. NEVER use a circular saw blade that does not carry theHardieBlade logo4. NEVER dry sweep — Use wet suppression or HEPAVacuum5. NEVER use grinders6. Always follow tool manufacturer’s safety recommendationsP1 or P2 respirators can be used in conjunction with abovecutting practices to further reduce dust exposures. Additionalexposure information is available at www.jameshardie.co.nz tohelp you determine the most appropriate cutting method foryour job requirements. If concern still exists about exposurelevels or you do not comply with the above practices, youshould always consult a qualified industrial hygienist orcontact James Hardie for further information.10 James Hardie Eaves And Soffits Installation Manual February 2013 New Zealand

3 FramingWorking instructionsRefer to recommended Safe Working Practices before starting anycutting or machining of product.Score and SnapScore and Snap is a fast and efficient methodof cutting the product using special tungstentipped Score and Snap knife.Preferably score on the face side of theproduct. Score against a straight edge and repeat the action toobtain adequate depth for clean break – normally 1/3 of sheetthickness. Snap upwards to achieve break. Smooth any roughedges with a rasp.Hand GuillotineMake guillotine cut on the off-cut side of line toallow for the thickness of the blade.Fibreshear Heavy DutyAn electrically powered, fast, clean and effortlessway of cutting James Hardie building products,especially around curves such as archways.Make Fibreshear cut on the “off-cut” side of theline to allow for the thickness of the shear.HardieBlade Saw BladeThe HardieBlade Saw Blade used with a dustreducingand HEPA vacuum extraction allows forfast, clean cutting of James Hardie fibre cementproducts. A dust-reducing saw uses a dustdeflector or a dust collector connected to a vacuum system. Whensawing, clamp a straight-edge to the sheet as a guide and run thesaw base plate along the straight edge when making the cut.Hole-FormingFor smooth clean cut circular holes:Mark the centre of the hole on the sheet. Pre-drill a pilot hole.Using the pilot hole as a guide, cut the hole to the appropriatediameter with a hole saw fitted to a heavy duty electric drill.For irregular holes:Small rectangular or circular holes can be cut bydrilling a series of small holes around the perimeterof the hole then tapping out the waste piece from thesheet face. Tap carefully to avoid damage to sheets,ensuring that the sheet edges are properly supported.Storage and HandlingAll James Hardie building products should be stored to avoiddamage, with edges and corners of the sheets protected fromchipping. James Hardie building products must be installed in adry state and be protected from rain during transport and storage.The product must be laid flat under cover on a smooth level surfaceclear of the ground to avoid exposure to water or moisture, etc.QualityJames Hardie conducts stringent quality checks to ensure thatany product manufactured falls within our quality spectrum. It isthe responsibility of the builder to ensure that the product meetsaesthetic requirements before installation. James Hardie will notbe responsible for rectifying obvious aesthetic surface variationsfollowing installation.3.1 TIMBER FRAMETimber framing must be in accordance with NZS 3604 TimberFrame Buildings.Specific design to NZS 3603 and AS/NZS 1170 can also beundertaken providing that:• the framing centres do not exceed those given in this specification• the framing member widths conform to this specification.Also refer to the Approved Document for NZBC Clause B2‘Durability’ and NZS 3602 (Timber and Wood-Based Productsfor use in Buildings) regarding timber treatment requirements andallowable moisture contents in timber for various components of thebuilding. Also refer to the framing manufacturer’s literature for furtherguidance on the use of treated timber.3.2 STEEL FRAMEThe figures in this brochure are drawn for timber framing. However,steel framing and furring channels can also be used.All metal framing centres are to be the same as specified for timberframe in this manual.Steel framing members must be fabricated from light-gauge sheetsteel 0.55mm thick minimum to 1.6mm maximum. If heaviersections are used difficulties may be experienced in fixing theself-drilling, self-tapping fasteners. Refer to specific details for theminimum flange width requirements.Sheets must not be fixed directly to drawn steel or hot-rolledsteel sections. These must first be battened out with ex 50mmthick(40mm minimum) timber battens or light-gauge metal furringchannels.Screw-fix 6mm or thicker sheets only.Screw fixings can be finished flush or sunk a maximum of 0.5mmbelow the sheet surface ready for filling.NOTE: The fasteners must not be over driven as will reduce the holding capaciity of the sheet.3.3 FRAMING SET-OUTFor the framing set-out of 450mm and 600mm-wide soffit refer toFigure 1.For the framing set-out of 750mm-wide soffits refer to Figure 2.For the framing set-out of 900mm and 1200mm-wide soffit refer toFigure 3.Pre-finished steel fascia/guttersWhen pre-finished steel fascia/gutters are used the soffit edge mustbe supported 4mm min. into fascia recess, similar to Figure 27.Ribbon board to be continuous for product fixing.NOTE: Because of the limited fascia groove available with some metal fascias a supportingribbon board will be required with fixings at 300mm centres maximum. Pre-finished soffits candistort due to surface tension when adequate edge support is not provided.James Hardie Eaves And Soffits Installation Manual February 2013 New Zealand 11

Soffit BearerCentres (Mm)This installation manual covers the use of James Hardie Eaves andSoffits for buildings within the scope of NZS 3604. For all otherbuildings specific engineering design is required.Figure 1: Eaves and soffits 450mm, 600mm wide*HardieFlex Sheet 6mm or Villaboard Lining 6mm must be used inEH Wind Zone with soffit bearers maximum 600mm centres.3.4 Batten requirementsBattens are required when sheets are fixed over:• Gypsum board exceeding 20mm in thickness• Softboard, polystyrene or similar• Concrete, masonry block or brick.Timber battening is to be a minimum of 35mm deep x 40mm wideto achieve adequate sheet nail penetration.Figure 2: Eaves and soffits 750mm wideSteel battens must be minimum 0.55mm thick, 23mm deep andhave a bearing surface of 38mm min. Battens must be galvanised tomeet the durability requirements of the New Zealand Building Code(NZBC) and fixed to manufacturer’s specifications. All batteningcentres and sheet fixing is to be strictly in accordance with theframing and fixing required by this manual. Care must be takento ensure the battens are packed and aligned to give a true evensurface for the sheets to be fixed. Check the face of the battenswith a long straight-edge before fixing sheets.3.5 SKILLION ROOF DESIGNWhen installing soffit linings direct to skillion roof framing ensurethat sufficient ventilation has been provided within the roof space.The temperatures within these smaller roof spaces can reachextreme levels in certain conditions and this can cause cracking inflush stopped joints due to excessive movement in framing. Theframing in skillion soffits and ceiling also need engineering designconsideration. General design guide is to provide control joints at4.8m x 3.6m in either direction when fixing to this type of framing.For narrow strip soffits provide control joints at 4.8m centres.Notes1. HardieFlex nails are the usual fixing method for HardiesoffitLining. The Fastfix method can also be used as an alternative.2. When Fastfix fastenings are used refer to Table 7 and Figure25 and 27.12 James Hardie Eaves And Soffits Installation Manual February 2013 New Zealand

HardieFlex ® nails are the usual fixing method for Hardiesoffit ®Lining. The Fastfix method can also be used as an alternative.2. When Fastfix fastenings are used refer to Table 7 and Figure25 and 27.4.1 GENERALRefer to Table 12 and Figure 1, 2 and 3 regarding nail fixing centres,for framing and types of fasteners.The eaves/soffits must be sealed against claddings to minimisemoisture ingress behind the claddings. The roof must have beeninstalled before installing the soffits linings. Where the soffits aresloping upwards away from the wall, a mechanical flashing mustbe provided in the soffit to wall junction. The flashing is fixed undersoffit lining and laps over the face of cladding by 35mm min. Referto Figure 18.4.1.1 Drip EdgeAll soffit linings must either be installed with a grooved fascia, referFigure 13, or with exterior cladding which forms a drip edge belowthe soffit lining by 15mm min. Soffit linings are generally fitted intothe recess formed in fascia board to form the drip edge.4.1.2 STRUCTURAL CEILING DIAPHRAGMSHardieFlex Eaves Lining and Villaboard Soffit Lining are suitable foruse in structural ceiling diaphragms as per NZS 3604.Refer to the James Hardie Bracing Design Manual.4.1.3 CURVED APPLICATIONSHardieFlex Eaves Lining and Villaboard Soffit Lining can be used forcurved applications.Table 14Curved Lining — Soffit Batten SpacingRange of Radii (mm) soffit batten spacing (mm)1800 200Above 1801 to 3000 300Above 3001 4004.1.4 Fastfix fastenersFastfix fasteners (38mm long) can be used as an alternative fixing forprefinished soffit and ceiling systems in conjunction with adhesives.Drill a 6mm-diameter hole through the sheet and framing to insertthe Fastfix fastener. In timber the hole must be 40mm deep.4.1.5 MAsking TAPEThe recommended masking tape for use with Silkline Soffit Liningand Eclipsa Eaves Lining is 3M Scotch Blue painters tape 2090 orSellotape 5855 longlife. This tape can only be left on the SilklineSoffit Lining or Eclipsa Eaves Lining for maximum 7 days, otherwisetape removal may cause paint loss.4.1.6 FIRE RATED SOFFITSA fire rating of 30 or 60 minutes can be achieved in a soffit whenusing 6mm or 9mm Villaboard Soffit Lining or 6mm or 7.5mmHardieFlex Sheet when James Hardie FRR wall systems are used.For full details refer to the James Hardie Fire and Acoustic DesignManual or Ask James Hardie on 0800 808 868.4.2 Fastener DurabilityFasteners used in external applications must meet the minimumdurability requirements of the NZBC. NZS 3604 specifies therequirements for fixing’s material to be used in relation to the exposureconditions and are summarised in Table 15.The minimum bending radii are shown below.James Hardie Eaves And Soffits Installation Manual February 2013 New Zealand 13

Use of 6mm thick sheets will minimise the deflection and enhancethe impact resistance.2. Sheets can be jointed as per Section 4.3. Do not screw fix 4.5mm thick sheets.4.4 HardieFlex EAVES LININGFor framing and fixing schedules refer to Section 3.All sheet edges are to be supported by framing or a fascia board.Fixings are to be at 200mm centres to all framing (refer Figures1and 2).NOTES1. Use of 6mm thick sheets will minimise the deflection and enhancethe impact resistance.2. Sheets can be jointed as per Section 4.3. Do not screw fix 4.5mm thick sheets.4.5 HardieGroove SOFFIT Lining FixingmethodFor framing and fixing schedules refer to Section 3.The recommended fixing methods are combined nail and adhesiveor screw and adhesive. However, screw or nail fixing only is anoption. (Refer Figure 4).To achieve a concealed joint, butt the long edges together (halfgrooved).(Refer Figure 5).NOTES1. Do not place nails or screws within 100mm of the adhesivedaubs.2. Suitable fixings are HardieDrive stainless steel 30mm x 7gwood screws, HardieFlex galvanised nails 40 x 2.8mm and 316stainless steel nails 40 x 2.8mm.3. Use only stainless steel fixings in sea spray zones.4. When butt jointing short ends of HardieGroove Lining in ceiling/soffit applications, the short edges must be cut square and havechamfer formed.Nails must be finished flush with the sheet surface. Screw headscan be finished 1-2mm below the sheet surface and stopped.In steel framing the fasteners should be driven as close as possibleto the stud corners to avoid deflection of the stud flange.Figure 5: Sheet edge and groove detail4.5.1 FINISHINGOnce the sheets are in place, fill over all driven fixings with JamesHardie Base Coat to the required level of finish.14 James Hardie Eaves And Soffits Installation Manual February 2013 New Zealand

change lines (refer Figure 14). Framing members (to which thesheet is fixed) must not continue across this control joint. Sheetsshall be fixed across the ceiling joists or ceiling battens (referFigures 15 and 16). Figures 12 and 13 show control joints with thebattens running in the same direction as the sheet joint.Figure 13: Timber control joint detailFigure 11: Control joint layoutFix at 200mm centres with2.8mm HardieFlex nailFigure 14: Directional changes to soffits and ceilings —control jointFigure 12: Steel ceiling batten control joint detail4.7.6 Fixing OPTION OneA smooth surface finish is obtained by minimising the visiblesheet fixings. For painted finishes the combined nail or screw andadhesive method gives this superior finish (refer Figure 19).Fix at 200mm centres down each sheet end with edge fixings ineach joist or batten. Double-fix in the centre of each joist or batten(refer Figure 19). Do not place nails or screws within 100mm ofadhesive daubs. Daubs of wallboard adhesive 25mm diameter and15mm thick must be applied to the intermediate joists or battens at250mm centres (refer Figure 19).When nogs are not installed for perimeter support, the unsupportededges between ceiling joists or battens must be supported withback blocking using a 300-400mm wide Villaboard Lining stripadhered to rear face and centred between framing.James Hardie Eaves And Soffits Installation Manual February 2013 New Zealand 17

6 JOINTING AND FINISHINGFOR VILLABOARD LINING6.1 generalVillaboard Soffit Lining is finished with paint complying with parts 7,8, 9 and 10 of AS 3730. The application and maintenance must bein accordance with the manufacturer’s specifications.note: Before flush stopping sheet edges must be sealed withMultiplast resin, water proofing admixture or other similar products.6.2 glancing lightIn some instances, due to glancing light, set joints may benoticeable in Villaboard Lining walls, especially where paint finisheshave a high gloss level. Work closely with your builder or designerto minimise this.Table 17Levels of FinishesLevel offinishArtificial lighting needs to be considered in relation to soffits.Where glancing light is an issue its effect can be lessened by:• Artificial light shading devices.• The use of light coloured, matt finish paints.6.3 LEVEL OF FINISHESDifferent levels of finishes are typically specified for differentapplications. Higher levels of finishes are used to address theglancing light issues with painted Villaboard Soffit Lining referredto above. A description of the various levels of finishes and thejointing/coating requirements can be found in Table 17.Definition* Typical jointing/setting Finish0 This level of finish may be useful in temporaryconstruction.1 For use in plenum areas above ceilings, in areas wherethe work would generally be concealed, or in buildingservice corridors and other areas not normally open topublic view.2 For use in warehouse, storage or other areas wheresurface appearance is not of primary concern.3 For use in areas which are to receive heavy or mediumtexture (spray or hand applied) finishes or where heavywall paper coverings are to be applied as the finaldecoration. This level of finish is not generally suitablewhere smooth painted surfaces or light to medium wallcoverings are specified.4 This is generally the accepted level of finish fordomestic construction. It is used where light texturesor wall coverings and smooth textured finishes andsatin/flat/low sheen paints are illuminated by noncriticallighting.5 This level of finish is for use where gloss or semi-glosspaints are specified or where critical lighting conditionsoccur on satin, flat or low sheet paints.No stopping, taping, finishing oraccessories are required. The work isconfined to gluing or screwing/nailingsheets in place.Joints and corner joints will be set withJames Hardie Base Coat reinforced withperforated paper tape.Joints and corner joints will be set withJames Hardie Base Coat reinforced withperforated paper tape and James HardieTop Coat.Joints and corner joints will be set withJames Hardie Base Coat reinforced withperforated paper tape and James HardieTop Coat.Refer to flush jointing recommendationson page 22.All joints and corner joints will have tapeembedded in James Hardie Base Coatapplied over all joints, angles, fastenerheads and accessories.This application is applicable to recessededge sheets only. The use of square edgesheets will require a high build applicationand coating finish.Refer to page 23 steps 1–4 for jointing.Final James Hardie Base Coat applicationshould be feathered out to approximately200mm + each side of the joint. Then afull skim coat of James Hardie Top Coatmust be applied over entire sheet surfacein order to achieve a uniform finish.This application is applicable to recessededge sheets only.The use of square edge sheets will requirea high build application and coating finish.For use in areas where finishing and stopping isnot considered necessary.Surface free from excess jointing compound. Toolmarks and ridges are generally acceptable.Minor tool marks and ridges are generallyacceptable.This level of finish must be sufficiently smoothto accept heavy vinyl, tiles or textured coatingswithout blemishes.For use where light-texture coatings or wallpaperor other lightweight wall coverings are to beapplied. For painted finishes in non-critical lightingareas flat and low-sheen textured paints are tobe applied. Gloss and semi-gloss paints are notgenerally suitable over this level of finish as anyminor blemish will show under critical light.The weight, texture and sheen level or wallcoverings applied over this level of finish must becarefully evaluated. Joints and fasteners must beadequately concealed if the wall-covering materialis lightweight, contains limited pattern, has agloss finish, or any combination of these featuresis present. Unbacked vinyl wall coverings are notsuitable over this level of finish.This level of finish is for use where gloss, semigloss,low-sheen or non-textured paints arespecified or where critical lighting conditionsoccur.*Reference: AS/NZS 2589.1: ‘Gypsum lining in residential and light commercial construction — Application and finishing.
