Please contact the component manufacturer for information on their warranties and further information on their products.

SAFE WORKING PRACTICES

WARNING – DO NOT BREATHE DUST AND CUT ONLY IN WELL VENTILATED AREA
James Hardie products contain sand, a source of respirable crystalline silica. May cause cancer if dust from product is inhaled. Causes damage to lungs and respiratory system through prolonged or repeated inhalation of dust from product. Intact fibre cement products are not expected to result in any adverse toxic effects. The hazard associated with fibre cement arises from the respirable crystalline silica present in dust generated by activities such as cutting, rebating, drilling, routing, sawing, crushing, or otherwise abrading fibre cement, and when cleaning up, disposing of or moving dust. When doing any of these activities in a manner that generates dust, follow James Hardie instructions and best practices to reduce or limit the release of dust, warn others in the area and consider rotating personnel across the cutting task to further limit respirable silica exposure. If using a dust mask or respirator, use an AS/NZS1716 P1 filter and refer to Australian/New Zealand Standard 1715:2009 Selection, Use and Maintenance of Respiratory Protective Equipment for more extensive guidance and more options for selecting respirators for workplaces. For further information, refer to our installation instructions and Safety Data Sheets available at www.jameshardie.com.au. 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

Position cutting station so wind will blow dust away from the user or others in working area.
Warn others in the area to avoid dust.
Consider rotating personnel across cutting tasks to further limit respirable silica exposures.
Use one of the following methods based on the required cutting rate:
Best
Villaboard™ knife
Hand guillotine
Fibreshear
Better
Position the cutting station in a well-ventilated area. Use a dust reducing circular saw equipped with HardieBlade™ Saw Blade or comparable fibre cement blade and well maintained M-class vacuum or higher with appropriate filter for capturing fine (respirable) dust. Wear a properly-fitted, approved dust mask or respirator (minimum P1).

CUTTING INDOORS

Cut only using VillaboardTM knife, hand guillotine or fibreshears (manual, electric or pneumatic).
Position cutting station in a well-ventilated area.

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

IMPORTANT NOTES

For maximum protection (lowest respirable dust production) James Hardie recommends always using best practice cutting methods where feasible.
NEVER use a power saw indoors or in a poorly ventilated area.
ALWAYS use a dust reducing circular saw equipped with a sawblade specifically designed to minimize dust creation when cutting fibrocement
– preferably a sawblade that carries the HardieBlade™ logo or one with at least equivalent performance – connected to a M class or higher vacuum.
NEVER dry sweep – Use wet suppression, or an M class vacuum or higher with appropriate filter.
NEVER use grinders.
ALWAYS follow tool manufacturers’ safety recommendations.
ALWAYS wear a properly fitted, approved dusk mask, P1 or higher

DUST MASKS AND RESPIRATORS
As a minimum, an AS/NZS1716 P1 respirator must be used when doing any activity that may create dust. For more extensive guidance and options for selecting respirators for workplaces please refer to Australian/ New Zealand Standard 1715:2009 “Selection, Use and Maintenance of Respiratory Protective Equipment”. P1 respirators should be used in conjunction with the above cutting practices to minimise dust exposure. For further information, refer to Safety Data Sheet (SDS) available at www.jameshardie.com.au. 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 INSTRUCTIONS

Refer to recommended safe working practices before starting any cutting or machining of product.
Score and snap
Score and snap is a fast and efficient method of cutting James Hardie™ building products using James Hardie’s Villaboard™ 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 one third of sheet thickness. Snap upwards to achieve break. Smooth any rough edges with a rasp.

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

Fibreshear
An 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 Blade
The HardieBlade™ Saw Blade used with a dust-reducing saw connected to a M class or higher vacuum extraction allows for fast, clean cutting of James Hardie™ fibre cement products. A dust-reducing saw uses a dust deflector or a dust collector which can be 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-FORMING

For 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 the sheet edges are properly supported.

STORAGE AND HANDLING

To 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 rain 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.

QUALITY

James Hardie conducts stringent 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.

FRAMING

GENERAL

Versilux™ lining can be fixed to either timber or light gauge domestic type steel framing. The framing used must comply with the relevant building regulations and standards and the requirements of this guide.

TIMBER

Use only seasoned timber. Unseasoned timber must not be used as it is prone to shrinkage and can cause Versilux™ lining and frames to move. The minimum stud width is typically 35mm. However, where butt jointing is used the minimum stud width is 38mm at the joint. See Figure 13 and 14.
‘Timber used for house construction must have the level of durability appropriate for the relevant climate, expected service life and conditions including exposure to insect attacks or to moisture, which could cause decay.’
Reference AS1684.2 – 2010 ‘Residential Timber Framed Construction’.

STEEL

The minimum size for steel stud framing should be 64mm deep x 0.55mm base metal thickness (BMT).
Steel framing must be designed in accordance with AS/NZS 4600 – 1996 Cold Formed Steel Structures.
Steel sections shall be galvanised or zinc coated with a minimum BMT of 0.55mm and a maximum BMT of 1.60mm. Studs must not be less than

PREPARATION

Ensure frame is square and work from a central datum line. Frames must be straight and true to provide a flush face to receive the sheeting.

NOTE
Trim sheets to suit frame if frame is not square.
A suggested maximum tolerance of between 3mm and 4mm in any 3000mm length of frame will give best results. Versilux™ lining will not straighten excessively warped or distorted frames and any warping may still be visible after the internal lining is applied.

CURVED WALLS

Versilux™ lining may be bent to accommodate curved walls. The minimum bending radii are shown, see Table 4.

TABLE 4 CURVED WALL MINIMUM BENDING RADII

| Along length (mm)| Across width (mm)
4.5mm Versilux™ lining| 1200| 1800
6mm Versilux™ lining| 1800| 2400
9mm Versilux™ lining| 3000| 4000

NOTE
The bending radii given above require no special pre-wetting of the sheet. To maintain the smoothness of the curve, studs are required at the spacings shown in Table 5.

TABLE 5 CURVED LINING – STUD SPACING

INSTALLATION

SHEET LAYOUT

Versilux™ lining is usually fixed vertically. Sheet joints must coincide with the centre line of the framing member.
NOTE

Where horizontal layout is required provide an in-line row of noggings to allow for fastening of the sheet edge.
All construction must be carried out in accordance with the relevant building regulations and standards.

FASTENERS

TIMBER FRAME FASTENER SELECTION

4.5mm, 6mm & 9mm Versilux™ lining| 30mm x 2.8mm Galvanised FC Nail*

If a smaller head size is desired for aesthetic reasons use 25mm x 2.5mm ring shank underlay nails.

STEEL FRAME FASTENER SELECTION

| 0.5mm-1.6mm BMT
4.5mm – 9mm Versilux™ lining| HardieDrive™ screw 25mm

NOTES
Fasteners should be driven flush as shown in Figure 2. Fasteners should be screwed as close as possible to the stud corners to avoid deflection of the stud flange. See Figure 3.

FIXING TO WALLS

Step 1
Place 6mm off-cut packers along floor as temporary support for sheets. This allows provision for frame movement. Put sheet in place as shown.

Step 2
Fix sheet starting from the centre of sheet and working outwards to avoid any druminess. For fastener spacings refer to Figures 6.

FIXING TO CEILINGS

In ceiling applications Versilux™ lining can be fixed either parallel or perpendicular to framing. See Figures 7 and 8 respectively.

NOTE
Do not fix sheets to the bottom chord of roof trusses. Batten these out first with timber battens or metal furring channels.

JOINTING AND CORNERS

JOINTING

PVC jointing
Versilux™ lining may be jointed using PVC straight jointers as shown in Figures 9-12.

Butt jointing

Versilux™ lining may also be butt jointed by positioning sheet edges along centreline of framing, see Figures 13-14.

CORNERS

External and internal corners can be finished using the appropriate PVC jointers as shown in Figures 15-17.
