IntroductionThis guide contains product information, technical specification, construction details and design considerations for the HardieSmart™ ZeroLot™ Wall System.

What is a "Zero Lot" Line Home?When a building has one boundary wall built against the property line the house is said to have a virtually "zero lot" line. This is common in terrace style homes.

HardieSmart™ ZeroLot™ Wall System comprises two HardieSmart™ Boundary Walls built back to back with at least one built modularly. The external wall face is fitted with a specialised pre-sealed cladding known as HardieZeroLot™ Panel designed for areas with restricted access for maintenance.

Advantages• Creates more usable space within the lot.• Maximises indoor space using a compact solution.• Flexible building process: the construction of

independent structures, rather than traditionalsemi-detached buildings.

• Connection to adjoining properties is not requiredas the system is built and placed in modules.

Minimum RequirementsThe HardieSmart™ ZeroLot™ Wall System is designed for dual and single zero lot boundaries. It is suitable for use in Class 1 and 10a timber-framed buildings with a Fire Resistance Level (FRL) requirement of 60/60/60 minutes or less. For higher FRL, please consult James Hardie.

To provide you with the best possible solution, we continually seek to update and enhance our guides. PLEASE ENSURE YOU HAVE OUR LATEST GUIDE BEFORE USE by visiting jameshardie.com.au or calling on 13 11 03.

Tools For Fibre Cement

A suite of tools are available for cutting and handling James Hardie™ fibre cement. Please refer to James Hardie's Best Practice Guide for more information.



HardieFire™ Insulation

Electrical cables and services adjacent to HardieFire™ insulationFoil facings are conductive to electricity. Care must be taken when installing HardieFire™ insulation in the proximity of electrical wiring and lighting fixtures. Avoid contact with uninsulated electrical cables and fittings. If required, HardieFire™ foil facing may be removed using a utility knife. Consult a qualified Electrician, or contact James Hardie for further information.

Storage and Handling

Store in an internal dry area, out of direct sunlight and not exposed to chemicals. It must not be installed during an electrical storm and it must be installed in a dry state to a dry surface and protected from weather during transport and storage. HardieFire™ insulation has not been designed to withstand prolonged direct exposure to the exterior elements. Ensure that the insulation is completely dry prior to fitting.

Protective EquipmentKeep exposure to a minimum and minimise quantities kept in work areas. Avoid contact with eyes. When handling and installing HardieFire™ insulation, to prevent irritation ensure you wear:• Safety goggles/glasses conforming to AS/NZS

1336,• Protective clothing such as gloves and long

sleeve shirts and trousers,• P1 or P2 respirators.

Before Installation• You must turn the mains power ‘Off’ before

entering the workspace. If in doubt, you mustconsult a licensed electrician.

• Care and safety measures must be followedwhen working in areas that contain live electricalwiring.

• Defective electrical cables, terminals or any otherelectrical wiring must be repaired by the relevantspecialist prior to installation.

• Ensure workspace has adequate and ampleventilation. If working in confined spaces, it isrecommended to use a HEPA vacuum or othersuitable dust extractors.

• Before entering workspace, complete a riskassessment inspection to identify hazardsincluding but not limited to electrical, site accessand ventilation.

CuttingIt is recommended to cut outdoors. If cutting indoors, please ensure that workspace is properly ventilated or HEPA vacuums/dust extractors are used.1. Position cutting station so wind will blow dust

away from the user or others in working area.2. Use either a hand saw or a reciprocating saw.

DisposalDiscard any waste pieces of HardieFire™ insulation in accordance with your local council guidelines. Dispose of the material in such a manner to prevent exposure and escape.

Further Health and Safety InformationFor more information refer to the HardieFire™ insulation SDS available at jameshardie.com.au.

Safe Work Practices

James 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. During installation or handling, ensure to follow James Hardie's Best Practice Book and SDS for James Hardie™ fibre cement products available at www.jameshardie.com.au.

Fibre Cement



Design ConsiderationsGeneralAll design and construction must comply with the appropriate requirements of the NCC and other applicable regulations and standards. The specifier or other party responsible for the project must ensure that the details in this specification are appropriate for the intended application and that additional detailing is performed for specific design or any areas that fall outside the scope of this specification.

Slab and FootingsThe slab and footings on which the building is situated must comply with AS 2870 ‘Residential Slabs and Footings – Construction’ and the requirements of the NCC.SLAB SEPARATION: For detached construction, the designer must ensure that there is suitable slab separation between dwellings. This can be achieved by using a flexible bond breaking material (e.g. material for control joints) when setting out the slab. Refer to NCC and local regulations for more information.

Termite ManagementDue to restricted access at zero lot boundary walls, a suitable and certified termite management mechanism in accordance with AS 3660.1 or a reticulation system must be installed at the boundary slab e.g. Termimesh, Cordon and alike. Please consult the relevant manufacturer for more information.

Boundary SetbackThe HardieSmart™ ZeroLot™ Wall System specifies a minimum setback of 12.5mm from the boundary line when capped and installed in accordance with this guide.

When the HardieSmart™ ZeroLot™ Wall System is not capped and is built against an existing structure, a minimum setback of 500mm is recommended. Due to exposure, the HardieSmart™ ZeroLot™ panels will need to be coated and maintained in accordance with this guide (see coating section).

Please note that council, state or other regulations may apply in your development which specify different setbacks, height, width and other design criteria. Additionally, confirmation in writing in the form of a statutory declaration from the registered owner of the adjoining premises may be required to demonstrate compliance. The designer or specifier must ensure that the system is fit for purpose and complies with the relevant requirements and regulations.

Fire ResistanceNCC Vol. 2 Section 3.7.1 requires boundary walls to maintain an FRL of 60/60/60 minutes. HardieSmart™ Systems have been assessed by the CSIRO Division of Building Construction and Engineering and the Building Research Association of New Zealand (BRANZ) in accordance with the principles of AS1530.4 (FCO-3222 and FCO-3036 Rev. D).

Bracing PerformanceFor two sided systems i.e. comprising of both James Hardie™ external cladding and internal lining products of ≥6mm in thickness, the bracing capacity is typically 4 kN/m for plain timber framing and standard fixing methods. The capacity may be increased to a range of 6-10 kN/m for other fixing methods and anchor rods of 12mm diameter. For more information and specification, the designer must refer to James Hardie's Structural Bracing Application Guide(designed in accordance with AS 1684 'Residential Timber Framed Construction'). James Hardie's Structural Bracing Application Guide contains fixing details and the bracing capacity for James Hardie™

sheet bracing and other fibre cement cladding. All design capacities quoted are Ultimate Limit State(ULS) figures and have been certified by consulting engineers, Cardno (NSW) Pty Ltd.

Thermal PerformanceThis guide outlines certified modelled Total R-values for HardieSmart™ Wall Systems. Use this information to assist in satisfying the minimum deemed to satisfy NCC thermal resistance requirements and in verification software tools.

Total R-values are based on using HardieWrap™ weather barrier with an emissivity of 0.16W/m2. The Total R-values for common systems are in accordance with AS4859.1:2002 including Amendment 1:2006 'Materials for Thermal Insulation of Buildings'.

Weather ResistanceThe external cladding of the HardieSmart™ ZeroLot™ wall system has been designed in accordance with Clause P2.2.2 of the NCC. For any variations, it is the responsibility of the designer or specifier to identify moisture related risks associated with any particular building design. Wall construction design must effectively manage moisture, accounting for both the interior and exterior environments of the building, particularly in buildings that have a higher risk of wind-driven rain penetration or that are artificially heated or cooled. All wall openings, penetrations, intersections, connections, window sills, heads and jambs must be flashed prior to cladding installation.

FIGURE 6 SECOND PANEL FASTENER CLEARANCE

Step 8 Coating (only for exposed areas)

HardieZeroLot™ panels are factory sealed with James Hardie's CoreShield™ technology penetrating sealer. This sealer has been designed for zero lot applications and does not require additional coating; however, for wall areas that are visible and fully exposed to the elements, you must apply a roll-on texture coat within 6 months of fixing. All sheets must be dry before painting. James Hardie recommends the application of a roll-on exterior texture coat system over the panels in accordance with the paint manufacturer’s specifications. Some environments require special coatings including coastal areas. Painting specifications are dependant on the paint chosen. Refer to the paint manufacturer for further information, product suitability, specifications, maintenance and details of their warranty.

Step 2 Set Out Slab or BaseInstall slab separation and termite management system in accordance with the Design Considerations section.

System Installation Steps Restricted Site Access

Step 1 Stage MaterialsThe components required for the HardieSmart™ ZeroLot™ Wall System must be staged during construction. Typically, a set of materials are required at framing stage and others at lining stage. The below lists do not consider all elements required for construction such as nails, adhesives, etc. Refer to the Accessories section for more information.

FRAMING STAGE: Involves building wall modules. These comprise of the following components:• Timber frame• HardieWrap™ weather barrier• HardieZeroLot™ panels• James Hardie™ Step Flashing• James Hardie™ 50mm wide Foam Back Sealing

Tape

NOTE: A small portion of HardieFire™ insulation may be required at framing stage for roof cavity, see installation sequence.

LINING STAGE:• HardieFire™ insulation• Villaboard™ lining• Fire and acoustic-rated joint sealant

FIGURE 7 SLAB SEPARATION

Step 3 Determine Wall Module SizeEnsure you have selected the optimum lengths and heights of wall modules. This is critical to achieve optimum speed of construction and ease of installation. Wall modules height and length should not exceed 3.6m. To determine wall module dimensions, you must consider the following:• HardieZeroLot™ panel sizes;• Boundary wall length and height (wall module must

not exceed storey height);• Module weight, please refer to Table 2.

When planning your wall module lengths, ensure cut edges are placed in the wall ends and intermediate modules are a multiple of the sheet width in length as the shiplap factory edge (Figure 8) is required for module jointing, refer to Figure 15.

TABLE 2 WALL MODULES WEIGHT FOR 600MM STUD CENTRE

Table Notes: Please note that masses and dimensions are approximate only. These are subjected to manufacturing tolerances and other factors such as moisture content. The weights listed below have been used in the values set out in Tables 3 and 4. It does not consider flashings, damp-proof course and any other elements not listed below:• Timber frame: 429 kg/m3. Assuming density of softwood

traditional pine timber studs with a moisture content of 16.2%, which may vary.

Step 4 Build Wall FramesBuild the frame modules on ground with maximum 600mm stud spacings. Add the required additional timber blocking at wall intersections.

Once pre-built, place the frame into position to check levelling. Ensure frame module is levelled and square (e.g. cross-braced).

FIGURE 10 LEVELLING WALL FRAMES

Step 6 HardieWrap™ Weather Barrier and Foam TapeAfter frames are levelled and braced, place back on the ground and install HardieWrap™ weather barrier. It is recommended to fix with a suitable hammer tacker and staples at 450mm centres. Overhang the wrap by min. 150mm from frame side edges. This is required when jointing wall modules, see Figure 15.

Step 5 Level & Brace

1. Ensure that on one end, the overlap of the HardieZeroLot™ panel is hanging off the frame by 25mm.

2. On the other end, the underlap should be 20mm inside the frame edge.
