3.2 Site Work

3.2.1 Loading And Unloading

are supplied on pallets suitable for forklift unloading. If crane offloading by slings is envisaged, special notification

must be made in advance or upon placing orders.

All pallets and crates can be safely handled by using a barge lift or hoisting equipment and straps. Steel cables should not be

used as it will damage both the pallet and the planks within.

When the crates have to be removed from a box container, care must be taken NOT to expose crates or pallets to the shock

of any impact, as the shock could result in cracks in the packing.

3.2.2 Transport To Site

Always drive the delivery vehicle as close as possible to the location where the planks are to be installed. When transporting

the planks, it is essential to firmly secure the pallets to prevent the planks from sliding or moving while in transit.

3.2.3 Storage

are supplied with protective plastic sheeting wrapped around the timber crates. This protection should not be

removed until site and structural conditions are prepared and ready for plank installation.

All must be stored flat on pallets and placed inside covered and dry conditions, optimising protection for stored

planks against exposure to weather and other unfavourable conditions.

Figure 1

Protective Plastic Sheeting

3.2.4 Handling Of

The following must be taken into consideration when handling .

Figure 2

Never carry on flat and middle

position, as this increases likelihood of breakage.

Figure 3

Hold the vertically at the edge.

Figure 4

When a single person needs to carry the

, hold it in the middle and keep hands

as far apart as possible to provide maximum

support to the length of the plank.

Figure 5

When two persons carry the , hold it

near both ends of the plank.

3.3 Cutting

offer easy workability with conventional tools, on or off construction sites. The method of cutting is dependent on

the amount of cutting. Cutting of the plank can be achieved using a stationary table saw, a circular saw or a jigsaw. Cutting

must take place in a dry environment. Dust control is advisable.

It is recommended that fibre cement saw blades (see Figure 8) are used to cut the planks on site. These blades have been

designed especially for fibre cement and when correctly employed a high level of finish can be achieved. The blade is uniquely

designed with vibration damping composite body construction and diamond tipped teeth shaped to give a tear-free edge.

When small amounts of cutting are required on site, an alternative to the recommended fibre cement saw blade is a carbide-

tipped flat trapezoidal tooth blade. This has a limited life and will need regular changing.

8

Figure 6

Fibre cement blade.

3.4 Drilling

should be drilled using preferred and more efficient tungsten carbide tipped drill bit with point angles of 60° to 80°

rather than the usual 120° type.

4 Design Specifications

4.1 Compliance

Designers and/or contractors responsible for the intended project should follow the details and recommendations specified in

this manual.

It is also wise to keep in mind that all designs and constructions should comply with the appropriate and relevant requirements

of current legal building codes, regulations and standards, both domestic and international.

The information provided in this manual is valid at the time of publication. Please consult Eternit or its nearest official representative

for further versions or updates.

4.2 Framing Considerations

can be installed using either timber framing or lightweight steel framing.

Always check that all framing is straight and true before receiving the planks.

Specific requirements for framing must be determined by a design engineer as per prevalent building codes prior to installation.

4.2.1 Timber Framing

can be installed direct fixed or drained cavity systems based on respective building code compliance.

Ensure timbers are properly seasoned and dry before installation.

Recommended framing for direct fixed systems (Figure 7):

• Studs at 600mm centres maximum for non-cyclonic regions.

• Noggings must be fitted flush between the studs at a maximum of 1200mm centres.

• Double studs may be needed at internal corners and sides of openings.

Recommended framing for drained cavity systems (Figure 8):

• Studs at 600mm centres maximum for non-cyclonic regions.

• For studs at 6000mm centres, noggings must be fitted flush between the studs at maximum 800mm centres.

• For studs at 450mm centres, noggings must be fitted flush between the studs at maximum 1200mm centres.

• Double studs may be needed at internal corners and sides of openings.

For Australia, AS 1684.2 must be used as reference for residential timber-framed construction.

Under the New Zealand Building Code, timber framing needs to comply with NZS 3604 or specifically specific design to NZS

3603 and AS/NZS 1170

4.3 Moisture Management

Designers and/or contractors responsible for construction must ensure that building exteriors are appropriately waterproofed.

This includes all wall openings, window sills, junctions and connections.

Selection of materials and installation needs to take into account the requirements of relevant standards and building codes. It

is always recommended that project specific details are undertaken by an experienced consultant with local knowledge of this

specific field.

4.3.1 Vapour Permeable Membranes

Building underlays must be installed in accordance with AS/NZS 4200.2 and material properties complying with AS/NZS

4200.1 or the equivalent local standards, codes and regulations.

In addition to the above, installation of the building underlay must also be in accordance with the manufacturer’s

recommendations.

4.3.2 Flashing

Prior to fixing , appropriate flashing and weatherproofing need to be applied at critical points such as:

• External corners

• Internal corners

• Window and door openings

• Penetration where pipes or wiring pass through the planks

12

4.4 Wind Pressure

It is the responsibility of the designated project engineer to determine the relevant and specific wind pressures. All structural

calculations must be done by an accredited structural engineer and in compliance with the relevant building codes. For the

maximum capabilities of , please consult the Eternit Technical Department.

4.5 Fasteners

Consideration of fastener durability will be influenced by material choice, environmental factors and compatibility of materials

in contact with fasteners. In general, fasteners of choice should be resistant to corrosion.

When is installed in coastal areas, Eternit recommends the use of stainless steel fasteners, especially within 1km

of sea coastlines or when local micro climatic conditions (exposure to salt environments, for example) require it.

Please consult fastener manufacturers for more information.

4.5.1 Fixing

Fix with fastener as specified in Table 1 using concealed fixing method as shown in Figures 9 and 10.

Following requirements must be observed:

• Fix into stud at 600mm centres maximum (as specified by structural calculations).

• The plank can be fix without pre-drilling when the fastener is at least 50mm from the end of the plank. For fasteners closer

than 50mm to the end, fastener positions need pre-drilling with a 3.0mm drill bit head.

• Fix at 20mm from top of the plank ends. See Figures 9 and 10.

• Fastener must be flush driven into the planks and at best embedded 0.5mm below the plank surface. See Figure 11.

5.3 Window Details

Window frames can be installed as either face fixed, where the flange or facing is installed over the , or recess fixed,

where the window is set back within reveals.

When referring to face fixed, a head flashing that projects a minimum of 15mm past each edge of the window facing or flange

should be installed. It is recommended that the front edge at the ends of the flashing is slightly bent to increase protection at

the top of the window.

The flashing details shown in Figures 20 and 25 are not to be regarded as exhaustive, nor are they suggested as being suitable

for all applications and environmental conditions. It is the responsibility of the designer and/or contractor to ensure the use of

suitable flashing details and materials in order to maintain a watertight building.

6 Finishing Painted is available factory finished in different range of colours and can be installed directly at site.

Raw is to be finished on site with a weatherproof coating to ensure durability and a long service life of the planks.

Use high grade exterior acrylic paint as a finishing coat.

Be sure to obtain and understand the paint manufacturer’s recommendations before commencing work.

7 Health & Safety As for all products containing quartz (e.g. concrete and clay), , when machined mechanically (cutting, sanding,

drilling) will release dust which may contain quartz particles. Inhalation of high concentrations of dust may irritate the airways.

Dust may also cause irritation of the eyes and/or skin. Inhalation of dust containing quartz, in particular the fine (respirable

size) dust particulate matter, in high concentrations or over prolonged periods of time, can lead to lung disease (silicosis) and

an increased risk of lung cancer.

• Avoid dust inhalation by using cutting equipment which features dust extraction or suppression accessories where

practicable.

• Ensure adequate ventilation in the work place.

• Avoid contact with the eyes and skin and inhalation of dust by wearing appropriate personal protective equipment (safety

goggles, protective clothing) and approved respirator, a dusk mask of at least type P2.
