1. Covertek 403 Plus can be direct fix or cavity fix and must be installed in a manner that prevents ponding of water.

2. Covertek 403 Plus must be fully supported by Thermakraft Safety Mesh 300mm x 150mm, hexagonal netting 50mm or 75mm. Or suitable strapping, Thermastrap recommended under aluminum roofing.

3. For roof pitches below 10 degrees, Covertek 405 or 407 recommended4. Must be laid firmly (tight) without creases. All laps either vertical or

horizontal must be a minimum of 150mm lap.5. Fix using stainless steel 8-12mm staples or 20mm flat head clouts, or

appropriate proprietary fastenings

COMMERCIAL: LONG-RUN METAL ROOFING >10°

1. Covertek 403 Plus shall be installed in a manner that prevents ponding of water by full support using Thermakraft Safety Mesh 300mm x 150mm, or hexagonal netting 50mm or 75mm. Or suitable strapping, Thermastrap recommended under aluminium roofing.

2. May be installed either vertically (same direction as cladding) or horizontally shiplapped.

3. All laps either horizontally or vertically must be at a minimum of 150mm.

4. To be lapped into gutter 20mm and extended up to and over ridge.5. May be unwound to the full length from the gutter to the ridge.

However, when ridge ventilation is required must be terminated at the ridge purlin to allow a free passage of air.

6. Flue penetrations must have a minimum distance of 50mm from the underlay (refer to NZ Metal Roof and Wall Cladding Code of Practice 4.3.8)

7. Must be free of tears and punctures, fit tightly and be lap taped around all penetrations (except flue penetrations), to provide drainage for any condensation, or surface water from leaks. NOTE: Penetrations where polybutylene water pipes have been installed. Refer Pipe Manufacturers for instructions on sealing penetrations.

8. Can be installed above the battens or purlins for profiled metal roof claddings and otherwise in accordance with NZBC E2/AS1.

Thermakraft Wall UnderlayINSTALLATION PROCEDURES

HANDLING AND STORAGE

EXPOSURE TIME

1. Fix Underlay with printed side facing the exterior 2. Fix to all exterior walls from below bearers to the

top plate. Pull the underlay tight and fix securely to the frame with fasteners such as galvanized Little Grippers, 6mm-8mm staples or 20mm large head galvanized clouts at 300mm centres horizontally and vertically. Additional fasteners should be used around each opening to be cut out.

3. Thermakraft underlays are available in two widths 2740mm and 1370mm. The 2740mm is generally wide enough to come from below the bottom plate to the top plate.

4. When fixing underlay to Steel framing the same procedures applies, use adhesive spray or tape or flat head screws to fasten to the framing or thermal break, the exterior cladding fastenings will act as the permanent fixings.

5. Cover all windows and door openings with underlay.6. It is recommended that the wall underlay is not cut and prepared for window installation until the arrival of the windows.7. A minimum of 150mm lap is required at joins, all vertical laps must be made over studs. Horizontal laps to be laid ship lap style allowing water to be shed

to the outer face of the membrane 8. When windows and doors are ready for installation, the underlay covering the openings should cut at 45 degree and folded into the opening and securely

fastened Thermakraft Aluband Window Sealing System is recommended as the window flashing system. 9. NB. In accordance with NZBC Acceptable Solution E2/AS1 Paragraph 9.1.8.5, wall wrap must be prevented from bulging into the drained cavity. Where

stud spacing is greater than 450mm Thermakraft stud strap run horizontal at 300 centres is an acceptable means of prevention. 10. Once installed Thermakraft underlays may be left exposed to the weather (refer table below for Maximum time) Thermakraft underlays will provide

temporary weather protection during construction allowing work to continue. Internal linings and insulation must not be installed until the exterior cladding is completed

11. Fastenings behind Brick Veneer Cladding must have an equivalent service life to that of Brick Veneer (50 years). Refer to NZBC 3604 Table 4.1, and 4.3. 12. Make good any forced tears with Thermakraft White GP tape. Any large areas which require repair may be covered with a second layer of underlay, a lap

of 150mm is required.

» Due to the width of the sheets care should be taken when installing in windy conditions due to the large sail effect. » Store in clean dry conditions, not in direct sunlight. » Ensure rolls are not damaged » There are no environmental issues associated with the use of Thermakraft underlays .

If in doubt, all insulation must maintain a minimum 100mm clearance from the luminaire.

INSuLATIoN AND DowNLIGhTS The FACTs

There are a number of different types of downlights available on the New Zealand market and without careful consideration, the thermal performance of buildings could be severely compromised.

Only rated downlights allow the insulation to abut the luminaire. All others require the insulation to maintain a minimum 100mm clearance. each un-rated downlight will reduce the thermal performance of the building envelope as a result of both the necessary insulation clearance around some fittings and possible air movement through the fitting itself.

The current safety standards for downlights in New Zealand actually allow the light-fitting to flame for up to 30 seconds when the luminaire fails. This provides significant fire risk, so careful selection of downlights as well as correct installation of the light fitting and surrounding insulation is crucial. Minimum insulation clearances around un-rated downlights are required for all types of insulation including polyester and fibreglass (glass wool) to reduce over heating and the risk of fire.

Downlight Ratings; Recessed Luminaire Class Labels (IeC/NZS 60598)

GreenStuf® polyester insulation meets all the relevant standards for insulating up to and around rated downlights.

GreenStuf® is classified non-flammable/non-combustable in accordance with the requirements of IeC/NZS 60598 and IeC 60695 for abutting and covering downlightsIssues around the use of un-rated downlights has caused some confusion regarding insulating around recessed fittings due to the risk of overheating and fire. GreenStuf® polyester insulation is fire safe. Put simply, if Greenstuf® is exposed to a naked flame it will melt away from the flame and self-extinguish. Specify and use only IC / CA-Rated luminaires with thermostat protection. This will allow the insulation (including GreenStuf® polyester) to abut the luminare without compromising safety or performance.

Safety InstructionsGreenStuf® 100% polyester insulation is completely safe and user-friendly and no protective clothing, specialist equipment or precautions are required to handle or install this product. GreenStuf® is non-irritant, non-toxic, and non-allergenic and that means no skin, throat or lung irritation on contact or following installation.

CAUTION: Electric cables and equipment partially or completely surrounded with any bulk thermal insulation may overheat and fail. This applies to wiring installed prior to 1989. Please follow these installation instructions.

Installation Tools For retrofitting insulation, we recommend you have the following: step ladder, lamp and extension cord or torch, sharp scissors or wide blade snap/disposable knife, installing stick – such as a broom handle - used for pushing the insulation into corners and hard to reach places in the ceiling.

Installation InstructionsWe recommend all thermal and acoustic insulation is installed in accordance with NZS 4246:2006 Energy Efficiency – Installing Insulation in Residential Buildings. Copies of this Standard are available from Standards New Zealand.

Cutting to size – always cut GreenStuf® slightly oversized to ensure a tight friction fit. GreenStuf® rolls can easily be torn across the width by hand. GreenStuf® can be cut down the length of the Pad/Roll using sharp scissors or by compressing the insulation under a timber off-cut and then cutting through with a sharp wide blade disposable knife. Heavier and higher density products can be cut using an ‘insulation knife’.

Pads and Roll Form

Insulate all areas of the wall and ceiling leaving no gaps. Off-cuts can be used to fill small spaces. Even small gaps will significantly reduce the overall thermal efficiency of the construction system. Do not compress insulation unless this is a design specification as this will affect the thermal performance.

Walls: GreenStuf® Roll Form product thicknesses vary with R-Value. Before you begin ensure you have the correct insulation to fit inside the wall cavity. GreenStuf® should be friction fitted inside the timber framing ensuring no gaps. All of the wall space in exterior walls should be insulated (i.e. from the top to the bottom plates).

With a drained cavity wall construction and stud spacings greater than 450mm, NZBC E2/AS1, 9.1.8.5 Wall Framing behind Cavities, requires stud straps to prevent insulation bulging into the cavity. Straps must be run at 300mm centres over the wall underlay.

Ceilings: GreenStuf® should be friction fitted between the ceiling joists and over ceiling battens where possible, or laid at right angles over the ceiling joists ensuring no gaps. All of the ceiling area should be covered with insulation (i.e. to the top plates of the exterior walls) except around heating flues, non CA/IC rated recessed lights and non-ducted extractor fans. Start the installation at the furthermost point from the ceiling manhole. Use the ‘installing stick’ to push the insulation into harder to reach places.

A 25mm ventilation gap between the roofing underlay and the insulation should be maintained at all times. A minimum gap of 200mm must be left around un-rated recessed down lights and ceiling exhaust fans, and a 50mm gap is required around metal heating flues and brick / concrete chimneys. Do not cover ceiling vents – simply insulate around them.

Where possible, insulation should be placed beneath electrical wiring to allow access for maintenance and to prevent possible over-heating.

Double-Layer Ceiling Installation: For higher R-Value installations we recommend a ‘double-layer’ installation to reduce thermal bridging and heat-loss through the timber construction. Lay the first layer between the ceiling joists and over the ceiling battens, and the second layer at right-angles to, and over the top leaving no gaps except around heating flues, chimneys, non CA/IC rated recessed light fittings and non-ducted extractor fans as detailed previously.

Retro-fit Ceiling: A ceiling blanket installation video is available online at www.greenstuf.co.nzThis pack complies with AS/NZS 4859.1 at the nominal weight recorded on the bale label.

2 James Hardie Rigid Air Barriers Installation Manual April 2016 New Zealand

1 Introduction

James Hardie manufactures a range of rigid air barriers such as HomeRAB® Pre-Cladding and RAB® Board.

HomeRAB Pre-Cladding is a 4.5mm thick fibre cement sheet which is sealed on the face and edges and is used as a rigid air barrier for residential buildings within the scope of NZS 3604. HomeRAB Pre-Cladding is manufactured in New Zealand by James Hardie and complies with the requirements of AS/NZS 2908.2.

It acts as temporary weather protection during construction, ideal for renovations or new construction. It is suitable for use as rigid underlay in residential buildings as per section 9.1.4 of E2/AS1 and complies with the requirements of Table 23 of E2/AS1. HomeRAB Pre-Cladding is suitable to withstand wind pressures experienced in all wind zones up to and including Very High (VH) wind zone as specified in NZS 3604. HomeRAB Pre-Cladding doesn't get fatigued or tear under the wind pressures exerted on it in the long term. HomeRAB Pre-Cladding has been tested to withstand wind pressures up to VH wind zone.

RAB Board is a 6.0mm thick fibre cement sheet which is sealed on the face and edges and is suitable for use as a rigid air barrier in Extra High Wind (EH) zones or in wind pressures up to 4.5kPa.

It complies with the requirements of Table 23 of E2/AS1.

It is suitable for use as rigid underlay as per the requirement of section 9.1.4 of E2/AS1. RAB Board is also suitable to withstand high wind pressures experienced on building facades where it creates a wind barrier which equalises pressure within the cavity to the external pressures. Flexible underlays can deteroirate caused by positive/negative pumping actions created by gusting winds within the cavity and on building facade.

Due to these pressures a building underlay may not perform as desired in the long term. RAB Board has been tested to withstand wind pressures up to 4.5kPa(ULS).

James Hardie rigid air barriers provide the following benefits:• Resistant to moisture damage and rotting when installed

correctly.

• Integral sealer applied on the face and edges repels moisture rapidly and helps resist moisture penetration.

• Provides temporary weathertightness to the building envelope until the final claddings are installed.

• Provides general rigidity to the entire structure.

• An efficient way to achieve structural bracing.

This manual covers the use of HomeRAB Pre-Cladding and RAB Board in external wall applications only. Further information relating to HomeRAB Pre-Cladding and RAB Board is also available in the following James Hardie design manuals:

• Fire and Acoustic Design Manual.

• Bracing Design Manual.

The Specifier or other responsible party for the project must ensure that the information in this manual is appropriate for the intended application and that specific design and detailing is undertaken for areas which are not covered in this manual.

Note: James Hardie rigid air barriers must not be used as external cladding.

2 Safe working practices

WARNING — DO NOT BREATHE DUST AND CUT ONLY IN WELL VENTILATED AREAJames Hardie products contain sand, a source of respirable crystalline silica which is considered by some international authorities to be a cause of cancer from some occupational sources. Breathing excessive amounts of respirable silica dust can also cause a disabling and potentially fatal lung disease called silicosis, and has been linked with other diseases. Some studies suggest smoking may increase these risks. During installation or handling: (1) work in outdoor areas with ample ventilation; (2) minimise dust when cutting by using either ‘Score and Snap’ knife, fibre cement shears or, where not feasible, use a HardieBlade™ Saw Blade and dust-reducing circular saw attached to a HEPA vacuum; (3) warn others in the immediate area to avoid breathing dust; (4) wear a properly-fitted, approved dust mask or respirator (e.g P1 or P2) in accordance with applicable government regulations and manufacturer instructions to further limit respirable silica exposures. During clean-up, use HEPA vacuums or wet cleanup methods — never dry sweep. For further information, refer to our installation instructions and Safety Data Sheets available at www.jameshardie.co.nz.

FAILURE TO ADHERE TO OUR WARNINGS, SAFETY DATA SHEETS, AND INSTALLATION INSTRUCTION MAY LEAD TO SERIOUS PERSONAL INJURY OR DEATH.

James Hardie recommended safe working practices

CUTTING OUTDOORS

Position cutting station so that wind will blow dust away from user or others in working area. Use one of the following methods based on the required cutting rate:

BEST• Score and snap • Hand guillotine • Fibreshear

BETTER• Dust reducing circular saw equipped with HardieBlade™

Saw Blade and HEPA vacuum extraction.

GOOD• Dust reducing circular saw equipped with HardieBlade™

Saw Blade

CUTTING INDOORS

• Cut only using score and snap, hand guillotine or fibreshears (manual, electric or pneumatic).

• Position cutting station in well-ventilated area

DRILLING/OTHER MACHINING

When drilling or machining you should always wear a P1 or P2 dust mask and warn others in the immediate area.

IMPORTANT NOTES:

1. For maximum protection (lowest respirable dust production), James Hardie recommends always using “Best” — level cutting methods where feasible

2. NEVER use a power saw indoors

3. NEVER use a circular saw blade that does not carry the HardieBlade™ logo

4. NEVER dry sweep — Use wet suppression or HEPA Vacuum

5. NEVER use grinders

6. Always follow tool manufacturer’s safety recommendations

P1 or P2 respirators can be used in conjunction with above cutting practices to further reduce dust exposures. Additional exposure information is available at www.jameshardie.co.nz to help you determine the most appropriate cutting method for your job requirements. If concern still exists about exposure levels or you do not comply with the above practices, you should always consult a qualified industrial hygienist or contact James Hardie for further information.


Working instructionsRefer to Recommended Safe Working Practices before starting any cutting or machining of product.

Score and SnapScore and Snap is a fast and efficient method of cutting the product using special tungsten tipped Score and Snap knife.

Preferably score on the face side of the product. Score against a straight edge and repeat the action to obtain adequate depth for clean break — normally 1/3 of sheet thickness. Snap upwards to achieve break. Smooth any rough edges with a rasp.

Hand guillotineMake guillotine cut on the off-cut side of line to allow for the thickness of the blade.

Fibreshear heavy dutyAn electrically powered, fast, clean and effortless way of cutting James Hardie building products, especially around curves such as archways. Make Fibreshear cut on the “off-cut” side of the line to allow for the thickness of the shear.

HardieBlade™ Saw BladeThe HardieBlade™ Saw Blade used with a dust-reducing saw fitted with HEPA vacuum filter is ideal for fast, clean cutting of James Hardie fibre cement products. A dust-reducing saw uses

Scored edge Straight edge

a dust deflector or a dust collector connected to a vacuum system. When sawing, clamp a straight-edge to the sheet as a guide and run the saw 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 appropriate diameter with a hole saw fitted to a heavy duty electric drill.

For irregular holes:• Small rectangular or circular holes can be cut by drilling a

series of small holes around the perimeter of the hole then tapping out the waste piece from the sheet face.

• �Tap carefully to avoid damage to sheets, ensuring that the sheet edges are properly supported.

Storage and handlingTo avoid damage, all James Hardie building products should be stored with edges and corners of the sheets protected from chipping.

James Hardie building products must be installed in a dry state and protected from weather during transport and storage. The product must be laid flat under cover on a smooth level surface clear of the ground to avoid exposure to water, moisture, etc.

QualityJames Hardie conducts quality checks to ensure any product manufactured falls within our quality spectrum. It is the responsibility of the builder to ensure the product meets aesthetic requirements before installation. James Hardie will not be responsible for rectifying obvious aesthetic surface variations following installation.

HomeRAB Pre-Cladding is fixed directly to the framing. The vertical joints are sealed over the face of the HomeRAB Pre-Cladding. HomeRAB Pre-Cladding is suitable for use behind all James Hardie claddings or alternative claddings such as brick, timber weatherboard, EIFS etc.

The RAB Board is suitable for use as a rigid air barrier in EH wind zone in residential or SED project applications to withstand high wind pressures in conjunction with cladding/commercial facades. In these applications, RAB Board is fixed directly to the framing. The vertical joints are sealed over the face of the RAB Board using joint flashing tape.

JAMES HARDIE RIGID AIR BARRIERJames Hardie rigid air barriers can remain exposed to the external elements for maximum 90 days prior to the external cladding being installed.

The James Hardie rigid air barriers can be used as a backing board behind stucco plasters. Refer to James Hardie Stucco Solution technical specification, E2/AS1 ‘External Moisture’ clause of the NZBC and BRANZ ‘Weathertight Solutions Stucco’ for further information on stucco plaster. The RAB Board can also be used as a backing board behind other proprietary claddings which comply with the NZBC requirements. Proprietary cladding must be installed as per their manufacturing specifications. In these applications, a building underlay must be used as a slip layer to cover RAB Board and ensure a separation between mortars and RAB Board. The RAB Board is fixed over a minimum 18mm thick cavity batten for these applications. The RAB Board may also be required over the framing to withstand high wind pressures within the cavity.

The claddings/facades used over James Hardie rigid air barriers must satisfy the various performance requirements of the NZBC.

Horizontal profiled metal and uPVC claddings must not be direct fixed over James Hardie rigid air barriers. These must be fixed over an underlay or overlay the James Hardie rigid air barrier using the cavity construction method.

Vertical profiled metal cladding can be direct fixed over James Hardie rigid air barriers with a flexible building underlay separator over to comply with manufacturers recommendations.

The cladding fastener length must be increased by 5mm minimum to maintain the required nail pull out strength.

In case of gable end trusses sitting on top plates of external wall frame, the frame size must comply with the minimum timber sizes stipuated for wall frames in Section 8 of the NZS 3604.

BracingFor bracing application the James Hardie rigid air barriers must be installed as per HomeRAB Pre-Cladding/RAB Board bracing details in the James Hardie Bracing Design Manual.

5 Installation

BOARD LAYOUT When using James Hardie rigid air barrier, building underlays are not required over the framing. HomeRAB Pre-Cladding/RAB Board has been tested and complies with the performance requirements of Table 23 of Clause E2 of the NZBC. The sheets are jointed keeping a gap of 2-3mm maximum between the sheet edges. The board must be cleaned of any dust before fixing the jointing tape over the joint.

Cut edges where exposed must be primed prior to installation with Dulux® Primacryl, Resene Quick Dry or similar.

The bottom edge of James Hardie rigid air barriers must overhang below the bottom plate by 15mm minimum. Refer Figures 21 and 22.

Vertical Joints Vertical joints must be sealed to stop the moisture ingress into the framing behind James Hardie rigid air barrier. The vertical joints are sealed over by running a 75mm wide sealing tape e.g. SUPER-STICK Building Tape / 3M All Weather Flashing Tape 8067.

A 50mm wide Inseal 3259 sealing tape can also be used where the CLD Structural Cavity Batten or timber cavity battens are fixed over the joint. The Inseal tape gets compressed permanently under the cavity battens to seal the joint.

Figure 5: Vertical joint

Inseal tapes must not be left exposed. Battens must be installed within 24 hours of the Inseal tape installation for the compression to happen. White protective tape must be removed before batten installation.

The sealing tapes must be pressed hard over the James Hardie rigid air barriers surface while fixing so that they achieve the required bond. The sealing tapes must not be exposed to elements for more than 90 days. This achieves the required protection when the cladding is installed. The claddings must be installed within 90 days.

NOTE: Refer to sealing tape manufacturers recommendations regarding the installation of their sealing tapes in cold climate conditions. It is recommended to warm up the sealing tapes eg when the air and substrate temperatures are below 10˚C. Check with tape manufacturer for their recommendations

Horizontal Joints The horizontal joint of James Hardie rigid air barriers must be flashed using a uPVC horizontal flashing or alternatively aluminium or colour steel Z flashings can also be used. Refer Figure 7. Leave a gap of minimum 15mm at the solid timber floor joist or as specified by the project engineer. The flashing must be lapped by a minimum 35mm on both sides of the joint.

For walls longer than 3m, horizontal uPVC flashing must be lapped by 50mm minimum and silicone sealed.

Rigid air barriers must not be fixed into floor joists.


Internal/External CornersJames Hardie rigid air barrier corner joints must be sealed using a 75mm minimum wide sealing tape. A 80mm wide Inseal 3259 sealing tape can also be used where the cavity battens are fixed over the corner joint to compress the Inseal tape.

When using a uPVC horizontal flashing in horizontal joints, the internal and external corner flashing joints must be sealed using a 75mm minimum wide joint sealing tape. Refer Figure 10.

When using James Hardie rigid air barrier as a backing board for stucco plaster, the vertical joints of James Hardie rigid air barrier are not required to be sealed using flashing tapes. The horizontal joints at floor level and in tall walls must be flashed to satisfy the requirements of clause E2 of the NZBC.

Figure 16: Stud to top plate connection

STUD TO TOP PLATE FIXINGTable 8.18 of NZS 3604 specifies two types of fixings i.e. Type-A with a fixing capacity of 0.7kN and Type-B with a fixing capacity 4.7kN. HomeRAB Pre-Cladding or RAB Board rigid air barriers have been tested and are verified as suitable alternatives to achieve the required stud top plate connectivity as mentioned above and no special use of straps/plates or wire dogs etc. is required.

For a 0.7kN connectivity, the standard fixing of HomeRAB Pre-Cladding and RAB Board using 40 x 2.8mm HardieFlex nails at 200mm centres maximum will achieve this.

For a 4.7kN connectivity, fix HomeRAB Pre-Cladding or RAB Board using 40 x 2.8mm HardieFlex nails at 75mm centres maximum to top plate with a minimum edge distance of 20mm. Refer to Figure 15.


Figure 17: Window flashing

FlashingsThe exposed timber framing around the window jamb can either be covered with a 150mm minimum wide flashing tape / sealing tape, refer Figure 19, or the jamb can be covered with a building underlay, refer Figure 20. The window sill must be dressed with a 150mm minimum wide flashing tape. The tape is sealed over the face of James Hardie rigid air barrier, refer Figure 16.

The James Hardie rigid air barrier surface must be clean, free of grime and dry before the tapes are applied. Some tape manufacturers require a primer tak spray be applied before fixing the tapes to the board surface to achieve a better tape adhesion. Check with the tape manufacturers for further information regarding minimum requirements etc.

3.1 generalthe engineer/designer is responsible for the frame design. the design wind pressures are to be calculated in accordance with as/nZs 1170 considering local factors.

3.2 TimBer graDethe minimum timber grade used must be no.1 framing grade in accordance with nZs 3631 (nZ timber Grading rules) or machine stress graded (MsG).

3.3 STuDSnominal 100 x 50mm studs must be provided at a maximum of 600mm centres. the framing centres can be reduced to suit the calculated wind pressure requirements as per engineer’s design. a nominal 75mm wide minimum stud is required at all vertical panel joints. this could also be achieved with two nominal 50mm wide studs spiked together.

3.4 nogSnominal 100 x 50mm minimum size nogs must be provided at 800mm centres maximum in general. check engineer’s design, clause 2.6 and clause 2.10 of this specification for other special requirements for nog centres. for horizontal aluminium socket joints a minimum 125mm wide framing member is required behind the joint. refer to figure 8 or 10.

3.5 framing TreaTmenTthe timber wall framing must be treated to a minimum of H1.2 treatment level. refer to the approved document for nZbc clause b2 ‘durability’ and nZs 3602 (timber and Wood-based products for use in buildings) regarding treatment requirements and allowable moisture contents of timber for various components of the building. refer to nZs 3640 (treatment of rough and sawn timber) for further information about timber treatment. also refer to the framing manufacturer’s literature for further guidance on the use of treated timber.

3.6 ToleranceSin order to achieve an acceptable wall finish, it is imperative that framing is straight and true. framing tolerances must comply with the requirements of project specification when specified.

4 air Barrier4.1 generalas the pressure within the cavity is equal to that on the face of cladding, air barrier used must be strong enough to withstand these wind pressures. fatigue due to positive and negative pumping actions of wind can damage the air barrier during the construction.

4.2 rigiD air Barrier (raB BoarD)the rab board is a fibre cement sheet which is sealed on the front face and edges and is used as a rigid air barrier. refer to rigid air barriers installation Manual for information regarding its installation. a horizontal gap is required between the rab boards at floor levels to accommodate any shrinkage of timber or creep of concrete and must be designed by the project engineer or designer.

4.3 BuilDing unDerlayfor buildings which are exposed to wind pressures up to 1.5kpa (uls), a building underlay may be used (a non-rigid air barrier) in place of the rab board. the designer must establish from the underlay manufacturer that the selected building underlay is suitable to withstand design wind pressures on the building. the warranties for such products must be sought independently from their manufacturers. the underlays must be installed in accordance with their manufacturer’s recommendations.

5 caviTy BaTTenS5.1 BaTTen SiZethe battens must be 45mm wide x 18mm deep minimum.

5.2 BaTTen layouTbattens must be fixed over the air barrier to all studs. double battens over double studs are required behind all vertical joints of the rainscreen. Where a building underlay (a non-rigid air barrier) is used, the battens must be provided at 300 mm centres when the studs are provided at 600 mm centres. When the studs are provided at 400mm centres, the battens are only required on studs.if the horizontal aluminium ‘t’ socket joint is used at floor levels or in between floor heights, then vertical packers are required on the nogs / dwangs. these vertical packers must be fixed at 300mm centres maximum to facilitate panel fixing. refer to figure 8. cavity battens must not be run continuously from lower floors to upper floors. they must have a gap between them at the floor levels to allow for the structural movements. refer figures 10 - 12.

5.3 caviTy BaTTen TreaTmenT battens must be treated to a minimum of H3.1 as defined in nZs 3602. the type of treatment chosen must be compatible with the durability requirements of other components used in the rainscreen system. refer to table 21 of e2/as1 for further information regarding the compatibility of materials.

6.1 generaltitan and exotec façade panel installed on cavity battens as per this specification acts as a rainscreen. any moisture ingress behind the rainscreen is managed on the face of rab board, where it either dries or drains out through the bottom of cavity.

6.2 rainScreen verTical JoinTVertical expressed joints 10mm wide are formed with a butyl inseal® strip fixed under the vertical sheet edges, refer to figure 7. fixings must only penetrate through the outer edge of butyl at 300mm maximum centres both sides. a packer is required on the intermediate studs to achieve surface flatness of rainscreen panels.

6.3 rainScreen horiZonTal JoinTHorizontal joints in the rainscreen can be formed in two ways, either using aluminium ‘t’ socket or a horizontal ‘Z’ flashing.an aluminium ‘t’ socket is used to form an expressed / negative horizontal joint. the aluminium ‘t’ socket is glued to the top rear edge of lower panel. fixings through the lower edge of upper sheet must not penetrate through the aluminium ‘t’ socket. refer to figure 8 or 10.normally a 2mm packer is required under the aluminium ‘t’ socket. use of two layers of dpc is recommended for this purpose. refer figure 8 or 10 for more information.‘Z’ flashings are normally used to drain off the moisture accumulated within a cavity and must be provided after every 7m height maximum. refer to figure 9. refer to table 20 of e2/as1 to select a suitable flashing material considering the durability requirements.

6.4 JuncTionSWhere ter meets other types of claddings or at wall intersections, a specific weathertightness design is required for this junction to withstand the moisture ingress considering design wind pressures as well as the structural movements. the specifier / designer is responsible for providing details for such junctions. James Hardie new Zealand has published standard junction details and are available on our website at www.jameshardie.co.nz. refer to it for further information and guidance.

6.5 caviTy venTilaTionpunchings in the James Hardie upVc vent strip permit a ventilation/drainage opening area of 1000mm2 per lineal metre of cavity.

7.1 general the moisture content of the timber frame and cavity batten must comply with the limitations of nZs 3602 prior to fixing the rab board and rainscreen panels. framing must be kept as dry as possible at all times during the construction phase to keep moisture contents within the limits as set out in this standard.

7.2 rigiD air Barrier (raB) BoarDfix the rab board to studs and nogs with 40mm x 2.8mm Hardieflex nails at 300mm c/c. the minimum distance of fixings from rab board edges must be 12mm.refer to table 2 for durability requirements of fixings. check clause 2.6 of this specification for bracing requirements. refer to rab board installation manual for further information on installation.

7.3 caviTy BaTTen fix battens to all studs using 40 x 2.8mm Hardieflex nails at 800mm c/c. fix small cavity packers 150mm long at bottom plate and nogs to facilitate panel fixing. refer to table 2 for durability requirements of fixings.

7.4 rainScreentitan and exotec façade panels shall be fixed in accordance with table 1. Note: ExoTec façade panels must only be screw fixed. All panel edges must be supported.the screws fixings must have a wood thread and a minimum 9 mm head diameter. the screws must be driven perfectly tight against the panels so that there is no movement between the panels and framing. the minimum edge distance of 18mm must be maintained when fixing screws or nails through the rainscreen panels. When countersunk screws are used the screw head must be set between 2.0mm minimum to 2.5mm maximum below the panel surface. use James Hardie countersinking drill bit to drill holes in the panel. the drill speed must be set between 400 and 560rpm. speeds greater than this will break the drill bit.

8 finiShing8.1 general all sealants must meet the relevant requirements of the nZbc. titan and exotec façade panels must be kept dry and under cover whilst in storage prior to fixing and before coating commences. panels must be coated within 90 days of installation. any penetrations as well as site cut sheet edges must be sealed with an appropriate sealer that is compatible with the finishing coat.

8.2 SealanTS application and use of sealants must comply with manufacturer’s instructions and be compatible with texture coating. check with sealant manufacturer prior to coating over sealants. some sealant manufacturers do not recommend coating over their product.

8.3 ScreW filler all countersunk screw holes must be filled with an epoxy filler. the countersunk holes must be clean and dry before they are filled. also ensure that the screws are perfectly tight and there is no movement between the panel and framing before the holes are filled. nuplex fairing cream or a similar product is recommended for this purpose. always refer to the epoxy manufacturer recommendation before use.

8.4 painTingfor painting/coating of titan or exotec façade panels, follow the recommended specifications of a recognised coating manufacturer. the general recommendation is one coat of acrylic primer and two coats of high build acrylic paint (total dft not less than 150

microns). prior to coating, the surface should be examined to ensure it is clean, sound, dry and free of any dust and contaminants. ensure all epoxy filled screw holes are sanded to finish flush with the surface of sheet to achieve a smooth finish. paints with a low lrV (light reflectance value) will absorb more solar heat and could cause the components used in the wall to expand and contract. this combined with glossy paint and wet timber used at the construction stage could lead to increased chances of fastener read through, as is common with any other building material.

9 mainTenanceit is responsibility of the specifier to determine normal maintenance requirements to maintain the effectiveness of building facade. the extent and nature of maintenance required will depend on the geographical location and exposure of the building. as a guide, it is recommended that the basic normal maintenance tasks shall include, but not be limited to:n Washing down exterior surfaces every 6-12 months*n re-coating exterior protective finishes**n regular inspection and repair if necessary of the façade panels, sealants, butyl inseal strips etc.n cleaning out gutters, down pipes and overflow pipes as requiredn pruning back vegetation which is close to or touching the building as well as ensuring the nZbc ground clearance requirements are maintained especially where gardens are concerned.n refilling the countersunk holes where the cracks start appearing in the paint film around epoxy fillers or where fastener read through becomes significant.

*Do not use a water blaster to wash down the cladding

**Refer to the paint manufacturer for washing down and recoating requirements related to ongoing paint performance.

10 STorage anD hanDlingtitan and exotec façade panels and rab board must be laid flat on a smooth level surface. edges and corners must be protected from chipping. to ensure optimum performance, store panels under cover and keep dry prior to fixing. if the sheets become wet, allow them to dry thoroughly before fixing. do not carry sheets on the flat, carry in the vertical position to avoid excessive bending.


11.5 DuraBiliTy titan and exotec façade panels and rab board, when installed and maintained as per the technical specification, will meet the durability requirements for claddings as required in the nZbc approved document b2 ‘durability’.

proDucT WarranTy

february 2013

WarranTy: James Hardie new Zealand (“James Hardie”) warrants for a period of 15 years from the date of purchase that the titan and exotec facade panel (the “product”), will be free from defects due to defective factory workmanship or materials and, subject to compliance with the conditions below, will be resistant to cracking, rotting, fire and damage from termite attacks to the extent set out in James Hardie’s relevant published literature current at the time of installation. James Hardie warrants for a period of 15 years from the date of purchase that the accessories supplied by James Hardie will be free from defects due to defective factory workmanship or materials.

nothing in this document shall exclude or modify any legal rights a customer may have under the consumer Guarantees act or otherwise which cannot be excluded or modified at law.

conDiTionS of WarranTy: The warranty is strictly subject to the following conditions: (a) James Hardie will not be liable for breach of warranty unless the claimant provides proof of purchase and makes a written claim either within 30 days after the defect would have become reasonably apparent or, if the defect was reasonably apparent prior to installation, then the claim must be made prior to installation.

(b) this warranty is not transferable.

(c) the product must be installed and maintained strictly in accordance with the relevant James Hardie literature current at the time of installation and must be installed in conjunction with the components or products specified in the literature. further, all other products, including coating and jointing systems, applied to or used in conjunction with the product must be applied or installed and maintained strictly in accordance with the relevant manufacturer’s instructions and good trade practice.

(d) the project must be designed and constructed in strict compliance with all relevant provisions of the current new Zealand building code (“nZbc”), regulations and standards.

(e) the claimant’s sole remedy for breach of warranty is (at James Hardie’s option) that James Hardie will either supply replacement product, rectify the affected product or pay for the cost of the replacement or rectification of the affected product.

(f) James Hardie will not be liable for any losses or damages (whether direct or indirect) including property damage or personal injury, consequential loss, economic loss or loss of profits, arising in contract or negligence or howsoever arising. Without limiting the foregoing James Hardie will not be liable for any claims, damages or defects arising from or in any way attributable to poor workmanship, poor design or detailing, settlement or structural movement and/or movement of materials to which the product is attached, incorrect design of the structure, acts of God including but not limited to earthquakes, cyclones, floods or other severe weather conditions or unusual climatic conditions, efflorescence or performance of paint/coatings applied to the product, normal wear and tear, growth of mould, mildew, fungi, bacteria, or any organism on any product surface or product (whether on the exposed or unexposed surfaces).

(g) all warranties, conditions, liabilities and obligations other than those specified in this warranty are excluded to the fullest extent allowed by law.

(h) if meeting a claim under this warranty involves re-coating of products, there may be slight colour differences between the original and replacement products due to the effects of weathering and variations in materials over time.

DiSclaimer: the recommendations in James Hardie’s literature are based on good building practice, but are not an exhaustive statement of all relevant information and are subject to conditions (c), (d), (f) and (g) above. James Hardie has tested the performance of the titan® façade panel and exotec® façade panel when installed in accordance with the titan® and exotec® façade panel technical specification, in accordance with the standards and verification methods required by the nZbc and those test results demonstrate the product complies with the performance criteria established by the nZbc. However, as the successful performance of the relevant system depends on numerous factors outside the control of James Hardie (e.g. quality of workmanship and design) James Hardie shall not be liable for the recommendations made in its literature and the performance of the relevant system, including its suitability for any purpose or ability to satisfy the relevant provisions of the nZbc, regulations and standards as it is the responsibility of the building designer to ensure that the details and recommendations provided in the relevant James Hardie installation manual are suitable for the intended project and that specific design is conducted where appropriate.
