WARNING

DO NOT BREATHE DUST AND CUT

ONLY IN WELL VENTILATED AREA

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. 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 TM 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 Material Safety Data Sheets available at www.jameshardie.com.au. FAILURE TO ADHERE

TO OUR WARNINGS, MATERIAL 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:

Better I Dust reducing circular saw equipped with

Saw blade and HEPA vacuum HardieBlade TM extraction.

Good I

Dust reducing circular saw equipped with

HardieBlade TM saw blade.

CUTTING INDOORS

I Cut only using score and snap, hand guillotine or

I 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 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 TM 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.com.au

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.

STORAGE AND HANDLING

To avoid damage, all James Hardie building products should be stored with edges and corners of the product 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.

SCYON ™ MATRIX ™ CLADDING

INSTALLATION INSTRUCTIONS PAGE 1 OF 8

INTRODUCTION AND SCOPE

General

Scyon ™ Matrix ™ cladding consists of Scyon ™ cavity trim installed over HardieWrap™ weather barrier to which the pre-sealed Scyon ™ Matrix ™ panels are fixed. Expressed vertical and horizontal joints are created to produce a panelised look.

This manual covers the use of the Scyon ™ Matrix ™ cladding in a residential facade application over a seasoned timber or a light-gauge steel frame.

Scyon ™ Matrix ™ cladding is not suitable for sloping walls or on a diagonal orientation.

DESIGN

General

All design and construction must comply with the appropriate requirements of the current Building

Code of Australia (BCA) and other applicable regulations and standards.

Responsibility

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.

construction must, at a minimum, comply with the requirements of relevant standards and the BCA.

HardieWrap™ weather barrier

HardieWrap™ weather barrier must be installed under Scyon™ Matrix™ cladding in accordance with the AS/NZS 4200.2 ‘Pliable building membranes and underlays – Installation’ and HardieWrap™

Technical Data Sheet.

HardieWrap™ weather barrier delivers a tripleshield of protection to help against external weather penetration, internal condensation build-up and external heat penetration. Additionally, it enhances the wall thermal performance, please refer to www.jameshardie.com.au

or www.accel.com.au for more information.

If using an alternate product in lieu of HardieWrap™ weather barrier, the designer must ensure that the product is fit for purpose and it has the following properties in accordance with AS/NZS 4200.1:

I

Vapour barrier - low or medium

I Water barrier - high

In hot humid areas of Australia, HardieWrap™ weather barrier may not be suitable, refer to the building designer for a suitable membrane and Ask

James Hardie ® on 13 11 03.

Soft compressible insulation installed between the front of the wall studs and directly behind the external cladding can cause installation issues and is thus not recommended.

Slab and footings

The slab and footings on which the building is situated must comply with AS 2870 ‘Residential slabs and footings – Construction’ and the requirements of the Building Code of Australia (BCA).

Adjacent finished grade must slope away from the building in accordance with local building codes, typically a minimum slope of 50mm minimum over the first metre.

Do not install external cladding such that it may remain in contact with standing water.

Flashing

All wall openings, penetrations, intersections, connections, window sills, heads and jambs must be flashed prior to cladding installation.

Ground clearances

Install James Hardie external cladding with a minimum 150mm clearance to the earth on the exterior of the building or in accordance with local building codes if greater than 150mm is required.

Maintain a minimum 50mm clearance between

James Hardie external cladding and roofs, decks, paths, steps and driveways.

NOTE

Greater clearance may be required in order to comply with termite protection provisions, see below for more information.

FRAMING

General

Frame set-out and construction is an important aspect to consider when planning the installation of

Scyon ™ Matrix ™ cladding. The way you install the panels will affect the way you build the frame.

Scyon ™ Matrix ™ panels and Scyon ™ cavity trim are installed either on or off stud, refer to Figures 4 and 5.

When installing on stud, the vertical panel joints are located centrally over the Scyon ™ cavity trim. For this method of installation it is important that the stud set-out accurately matches the vertical joint locations.

Alternatively, for the off-stud installation method, noggings must be installed at 800mm maximum centres, see Figure 5. The noggings must be aligned with the exterior plane of the frame to ensure that a flush surface is provided to accommodate the installation of the Scyon ™ cavity trim. Off stud fixing is not suitable in high wind loads, see Table 1. This table specifies the maximum stud spacings for Scyon Matrix cladding for Australian wind load classifications of

AS 4055 ‘Wind Loads for Housing’.

Termite Protection

The BCA specifies the requirements for termite barriers. Where the exposed slab edge is used as part of the termite barrier system, a minimum of

75mm of the exposed slab edge must be visible to permit ready detection of termite entry.

MOISTURE MANAGEMENT

General

It is the responsibility of 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.

In addition all wall openings, penetrations, junctions, connections, window sills, heads and jambs must incorporate appropriate flashing and waterproofing.

SCYON ™ MATRIX ™ CLADDING INSTALLATION INSTRUCTIONS

Timber

Use of timber framing must be in accordance with

AS 1684 - ‘Residential timber-framed construction’ and the framing manufacturer’s specifications.

Use only seasoned timber. Unseasoned timber must not be used because it is prone to shrinkage and can cause sheets and frames to move.

‘Timber used for house construction must have the level of durability appropriate for the relevant climate and expected service life and conditions including exposure to insect attacks or to moisture, which could cause decay.’

Reference AS 1684.2’ Residential timber-framed construction’.

Stud framing members must be a minimum of

70x35mm,

Steel

Use of steel framing must be in accordance with NASH standard for Residential and Low-Rise Steel Framing

Part 1: Design Criteria and the framing manufacturer’s specifications. Framing members must have a base metal thickness (BMT) between 0.55 to

1.6mm. The steel framing must have the appropriate level of durability required to prevent corrosion.

Framing members must have a Base Metal

Thickness (BMT) between 0.55 to 1.6mm. The steel framing must have the appropriate level of durability required to prevent corrosion. Stud framing members must be a minimum of 64x35mm.

Tolerances

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 panels.

A suggested maximum tolerance of between 3mm and 4mm in any 3000mm length of frame will give best results, see Figure 1. Scyon ™ Matrix ™ cladding will not straighten excessively warped or distorted frames and any warping may still be visible after the cladding is applied.

FIGURE 1 FRAME STRAIGHTNESS

FASTENERS

General

Suitable type of fasteners and spacings are provided on the following pages for both the

Scyon ™ cavity trim and Matrix ™ panels.

All fasteners specified should be driven flush as shown in Figure 2.

Drive screw flush

Unacceptable: over driven

FIGURE 2 NAIL FASTENER DEPTH

Screw fasteners should be screwed as close as possible to the stud corners to avoid deflection of the stud flange.

Fastener durability

Fasteners must have the appropriate level of durability required for the intended project. This is of particular importance in coastal areas, areas subject to salt spray and other corrosive environments.

Fasteners must be fully compatible with all other materials that they are in contact with to ensure the durability and integrity of the assembly.

In areas within 1km of a coastal area or corrosive environment, the Matrix TM panels must be painted immediately after fixing sheets, to minimise build up of contamination on the heads of the fasteners, as it may lead to fastener corrosion. Also refer to maintenance requirements and fastener section for more information.

Refer to the paint and fastener manufacturer for further information, suitable products and details of their warranty.

PRODUCT INFORMATION

Material

The basic composition of Matrix TM panels and

Scyon TM cavity trim is Portland cement, ground sand, cellulose fibre, water and proprietary additives.

James Hardie building products are manufactured to Australian/New Zealand Standard AS/NZS

2908.2 ‘Cellulose-Cement Products-Flat Sheet’.

Matrix TM panels and Scyon TM cavity trim are classified

Type A, Category 3 in accordance with

AS/NZS 2908.2

FIGURE 33 FACADE/SOFFIT JUNCTION

Sealants

Application and use of sealants must comply with manufacturer’s instructions. Sealants, if coated, must be compatible with the paint system. James

Hardie recommends the use of James Hardie TM joint sealant, which is a paintable polyurethane sealant.

FIRE RATED WALLS

Scyon TM Matrix TM clad walls can achieve fire ratings of 60/60/60 and 90/90/90 when constructed with additional fire rated linings as specified in the James

Hardie fire and acoustically rated walls design manual and construction of fire and acoustically rated walls technical specification.

Furthermore, as the Scyon TM Matrix TM cladding consists of Scyon TM cavity trim installed over the wall frame, the fire and water resistant plasterboard must be installed behind the HardieWrap™ weather barrier and Scyon TM cavity trim. It must not be directly installed behind the Scyon TM Matrix TM panels.

The length of the fasteners fixing the Scyon TM cavity trim to the wall frame will need to take into account the thickness of the fire and water resistant plasterboard.

STAINING

Stains containing linseed oil are specifically designed for wood and may not be suitable for James Hardie cladding products, primed or un-primed.

Semi-transparent stains can vary in uniformity of appearance depending on method of application and conditions and will require a high level of skill and craftsmanship to achieve a uniform appearance. Clear coats have not proven durable in exterior exposure and James Hardie considers them a maintenance item that may require application of a refurbishing sealer at regular intervals. James

Hardie does not warrant the appearance or durability of semi-transparent stains and clear coats.

FINISHES

General

Refer to the project specification for paint requirements. Scyon TM Matrix TM cladding and exposed Scyon TM cavity trim must be painted within

3 months of being fixed.

The rear of the Scyon TM Matrix TM panel must not be left permanently exposed to direct sunlight.

In order to seal cut edges or sanded patches, two coats of an appropriate primer should be applied at the time of cutting or sanding compatible with finish coating e.g. Wattyl Kill Rust Heavy Duty Primer,

Dulux AcraPrime 501/1 (water based) or equivalent.

James Hardie recommends the application of two coats minimum of a quality acrylic paint over the pre-primed Scyon TM Matrix TM panels and the exposed Scyon TM cavity trim in accordance with the paint manufacturer’s specifications. Painting selection and specifications is dependant on the paint chosen. Gloss paints are not recommended.

MAINTENANCE

The extent and nature of maintenance will depend on the geographical location and exposure of the building. As a guide, it is recommended that basic normal maintenance tasks shall include but not be limited to:

Washing down exterior surfaces every 6-12 months*

Periodic inspections should be made to ensure fasteners are adequately securing the panels to framing.

Re-applying of exterior protective finishes*

Maintaining the exterior envelope and connections including joints, penetrations, flashings and sealants that may provide a means of moisture entry beyond the exterior cladding.

Cleaning out gutters, blocked pipes and overflows as required.

Pruning back vegetation that is close to or touching the building.

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

Durability

Resistance to moisture/rotting

Matrix TM panels and Scyon TM cavity trim have demonstrated resistance to permanent moisture induced deterioration (rotting) by passing the following tests in accordance with AS/NZS 2908.2:

I

Water permeability (Clause 8.2.2)

Warm water (Clause 8.2.4)

Heat rain (Clause 6.5)

Soak dry (Clause 8.2.5)

Resistance to termite attack

Based on testing completed by CSIRO Division of

Forest Products and Ensis Australia James Hardie building products have demonstrated resistance to termite attack.

Resistance to Fire

Scyon TM Matrix TM cladding is suitable where noncombustible materials are required in accordance with C1.12 of the Building Code of Australia.

James Hardie building products have been tested by CSIRO in accordance with AS/NZS 3837 and are classified as conforming to Group 1 material

(highest and best result possible), with an average specific extinction area far lower than the permissible

250m2/kg, as referenced in Specification C1.10a

of the BCA.

Alpine regions

In regions subject to freeze/thaw conditions, all

James Hardie fibre cement external cladding must be installed and painted in the warmer months of the year where the temperature does not create freeze and thaw conditions or paint issues. The cladding must be painted immediately after installation. In addition, fibre cement cladding must not be in direct contact with snow and/or ice build up for extended periods, e.g. external walls in alpine regions subject to snow drifts over winter.

Furthermore, a reputable paint manufacturer must be consulted in regards to a suitable product, specifications and warranty. The paint application must not be carried out if the air temperature or the substrate temperature is outside the paint manufacturer’s recommendation including the specified drying temperature range.

James Hardie external cladding products are tested for resistance to frost in accordance with AS/NZS

2908.2 Clause 8.2.3.
