2.5 MOISTURE MANAGEMENTIt is the responsibility of the specifier to identify moisture related risks associated with any particular building design.

Wall construction design must effectively manage moisture, considering both interior and exterior environments of the building, particularly in buildings that have a higher risk of wind driven rain penetration. The buildings should also be ventilated sufficiently to control moisture accumulation due to condensation especially in artificially cooled/heated buildings.

Walls shall include those provisions as required by External Moisture Clause E2/AS1 of NZBC. In addition, all wall openings, penetrations, junctions, connections, window sills, heads and jambs must incorporate appropriate flashings for waterproofing. The other materials, components and installation methods used to manage moisture in external walls, must comply with the requirements of relevant standards and the NZBC. For further guidance on designing for weather tightness, refer to BRANZ Ltd. and the Department of Building and Housing updates on the following websites respectively, www.branz.co.nz and www.dbh.govt.nz.

In addition, the following issues must also be considered:

• Sealant must be installed where detailed in this literature.

• Where the walls are higher than two storeys, it is necessary to provide a horizontal flashing at the second floor level to drain the cavity.

• The installation of smoke chimneys, pipe penetrations and other fixtures etc. must not track moisture into the wall or restrict the drainage of moisture to the exterior.

2.6 STRUCTURE2.6.1 Timber FramingTimber-framed buildings must either be in accordance with NZS 3604 (Timber Framed Buildings) or designed as per specific engineering design. For a building requiring a specific engineering design, the framing stiffness must be equivalent to or more than the stiffness requirements of NZS 3604.

For specific design projects, the timber framing must be designed in accordance with the requirements of NZS 3603 and AS/NZS 1170.

For timber frame walls longer than 12m, it is best practice to allow for construction joints to accommodate movements generated due to timber shrinkage or deflections etc.

2.6.2 Steel FramingSteel-framed buildings must comply with the requirements of AS/NZS 3404 ‘Steel Structures Standard’ or specific engineering design requirements. Also refer to NASH 3405 steel framed buildings guidance document published by ‘National Association of Steel Housing’ (NASH).

2.6.3 Wind PressuresStria Cladding is suitable for use in all wind zones in New Zealand up to and including EH as defined in NZS 3604.

Stria Cladding is also suitable in specific design projects up to wind pressures of 2.5kPa uls.

2.7 FIRE RATED WALLSStria Cladding when fixed over timber cavity battens to external walls can achieve fire ratings up to 60/60/60 to comply with Clause C/AS1 of the NZBC when the walls are constructed in accordance with the current James Hardie ‘Fire and Acoustic’ Design Manual.

Stria Cladding is classified as a 'non-combustible' material suitable for use on walls close to a boundary.

4.4 CAVITY BATTENSStria Cladding to be installed on a cavity. The battens provide ventilation and drainage between the frame and the panel and are considered a “packer” only in this specification.

The timber cavity battens must be minimum H3.1 treated in accordance with NZS 3640 (Chemical preservation of rough and sawn timber) to comply with the durability requirements of B2/AS1.

Cavity battens must comply with E2/AS1 and:

• be minimum 18mm thick

• be as wide as the width of studs

• fixed vertically to studs

• be fixed by the cladding fixings to the main framing over the building underlay. Therefore until claddings are fixed the battens only need to be tacked to framing by 40 x 2.8mm or longer nails at 800mm c/c.

4.5 INTERMEDIATE SUPPORTWhere studs are at 600mm centres an intermediate means of restraining the building underlay and insulation from bulging into the cavity shall be installed. An acceptable method to achieve this is using one of the following options:

• intermediate cavity batten between the studs

• 75mm galvanised mesh

• polypropylene tape at 300mm centres fixed horizontally and drawn taut

No intermediate supports are required:

• when studs are spaced at 400mm centres

• when rigid air barriers instead of building underlays are used.

5.2 FASTENER DURABILITYFasteners must meet the minimum durability requirements of the NZBC. NZS 3604 specifies the requirements for fixing material to be used in relation to exposure conditions and are summarised in Table 2.

* (Zone C areas where local knowledge dictates that increased durability is required, appropriate selection shall be made). Microclimate conditions as detailed in NZS 3604, Paragraph 4.2.4 require SED.

Also refer to the NZBC Acceptable Solution E2/AS1’ Table 20 and 21 for information regarding the selection of suitable fixing materials and their compatibility with other materials.

5.3 FASTENER – SIZE AND LAYOUTStria Cladding must be fixed to framing using the fixings as specified in Table 3 below and follow the edge distance required for nails as shown in the details. Refer to Figure 7.

When using rigid air barrier like HomeRAB Pre-Cladding or RAB Board, the cladding fixing nails must be increased in length equal to the thickness of the rigid air barrier.

Table3Panel fixing

65x2.87mm D head or 60x2.87mm RounDrive nails

Fix nails at 100mm from top edge and 100mm from bottom edge/per board/per stud. Refer to Figure 12

For other fixing options Ask James Hardie on 0800 808 868.

• When fixing the panels using nail guns, refer to the nail gun manufacturer for information about nails and the type of nail gun to be used.

• Stud width of 70mm min required when using a vertical joint flashing. Refer Figure 9.

• D head nails - finish nails 2mm below panel surface.

• RounDrive nails - finish nails flush with panel surface.

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.

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

James Hardie recommended safe working practices

CUTTING OUTDOORS

1. Position cutting station so wind will blow dust away from the user or others in working area.

2. Use one of the following methods based on the required cutting rate:

BEST

• Dust reducing circular saw equipped with HardieBlade™ Saw Blade and HEPA vacuum extraction.

GOOD

• Dust reducing circular saw with HardieBlade™ Saw Blade.

SANDING/REBATING/DRILLING/OTHER MACHINING

When sanding, rebating, 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 manufacturers’ safety recommendations.

P1 or P2 respirators should 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.
