INTRODUCTION AND SCOPEGeneralScyon™ Matrix™ cladding consists of Scyon cavitytrim installed over vapour permeable membrane towhich the pre-sealed Matrix panels are fixed.Expressed vertical and horizontal joints are createdto produce a panelised look.

This manual covers the use of the Scyon Matrixcladding in a residential facade application over aseasoned timber or a light-gauge steel frame.Scyon Matrix cladding is not suitable for slopingwalls or on a diagonal orientation.

DESIGNGeneralAll design and construction must comply with theappropriate requirements of the current BuildingCode of Australia (BCA) and other applicableregulations and standards.

ResponsibilityThe specifier or other party responsible for theproject must ensure that the details in thisspecification are appropriate for the intendedapplication and that additional detailing is performedfor specific design or any areas that fall outside thescope of this specification.

Slab and footingsThe slab and footings on which the building issituated must comply with AS 2870 ‘Residentialslabs and footings – Construction’ and therequirements of the Building Code of Australia (BCA).

Ground clearancesInstall James Hardie external cladding with aminimum 150mm clearance to the earth on theexterior of the building or in accordance with localbuilding codes if greater than 150mm is required.

Maintain a minimum 50mm clearance betweenJames Hardie external cladding and roofs, decks,paths, steps and driveways.

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

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

NOTEGreater clearance may be required in order tocomply with termite protection provisions, seebelow for more information.

Termite ProtectionThe BCA specifies the requirements for termitebarriers. Where the exposed slab edge is used aspart of the termite barrier system, a minimum of75mm of the exposed slab edge must be visible topermit ready detection of termite entry.

MOISTURE MANAGEMENTGeneral It is the responsibility of designer or specifier toidentify moisture related risks associated with anyparticular building design. Wall construction designmust effectively manage moisture, accounting forboth the interior and exterior environments of thebuilding, particularly in buildings that have a higherrisk of wind driven rain penetration or that areartificially heated or cooled.

PAGE 2 OF 8 SCYON™ MATRIX™ CLADDING INSTALLATION INSTRUCTIONS

In addition all wall openings, penetrations, junctions,connections, window sills, heads and jambs mustincorporate appropriate flashing and waterproofing.Materials, components and their installation that areused to manage moisture in framed wallconstruction must, at a minimum, comply with therequirements of relevant standards and the BCA.

Vapour permeable membraneA vapour permeable membrane must be installedunder the Scyon™ cavity trim in accordance with theAS/NZS 4200.2 ‘Pliable building membranes andunderlays – Installation’ and the manufacturer’sspecifications.

The membrane must have the following propertiesin accordance with AS/NZS 4200.1:

� Vapour barrier - low or medium� Water barrier - high

The function of the vapour permeable membrane isto prevent moisture ingress by acting as a "drainageplane" whilst enabling water vapour build up frominside the frame to escape.

FlashingAll wall openings, penetrations, intersections,connections, window sills, heads and jambs mustbe flashed prior to cladding installation.

FRAMINGGeneralFrame set-out and construction is an importantaspect to consider when planning the installation ofScyon Matrix cladding. The way you install thepanels will affect the way you build the frame. Matrixpanels and Scyon cavity trim are installed either onor off stud, refer to Figures 4 and 5.

When installing on stud, the vertical panel joints arelocated centrally over the Scyon cavity trim. For thismethod of installation it is important that the studset-out accurately matches the vertical jointlocations.

Alternatively, for the off-stud installation method,noggings must be installed at 800mm maximumcentres, see Figure 5. The noggings must be alignedwith the exterior plane of the frame to ensure that aflush surface is provided to accommodate theinstallation of the Scyon cavity trim. Off stud fixing isnot suitable in high wind loads, see Table 1. Thistable specifies the maximum stud spacings forScyon Matrix cladding for Australian wind loadclassifications of AS 4055 ‘Wind Loads forHousing’.

TimberUse of timber framing must be in accordance withAS 1684 - ‘Residential timber-framed construction’and the framing manufacturer’s specifications.

Use only seasoned timber. Unseasoned timber mustnot be used because it is prone to shrinkage andcan cause sheets and frames to move.

‘Timber used for house construction must havethe level of durability appropriate for the relevantclimate and expected service life and conditionsincluding exposure to insect attacks or tomoisture, which could cause decay.’

Reference AS 1684.2’ Residential timber-framedconstruction’.

Stud framing members must be a minimum of70x35mm,

SteelUse of steel framing must be in accordance with AS 3623 - ‘Domestic metal framing’ and theframing manufacturers specifications.

Framing members must have a Base MetalThickness (BMT) between 0.55 to 1.6mm. The steelframing must have the appropriate level of durabilityrequired to prevent corrosion. Stud framingmembers must be a minimum of 64x35mm.

TolerancesEnsure frame is square and work from a centraldatum line. Frames must be straight and true toprovide a flush face to receive the panels.

A suggested maximum tolerance of between 3mmand 4mm in any 3000mm length of frame will givebest results, see Figure 1. Scyon Matrix cladding willnot straighten excessively warped or distortedframes and any warping may still be visible after thecladding is applied.

FASTENERSGeneralSuitable type of fasteners and spacings areprovided on the following pages for both the Scyoncavity trim and Matrix panels.All fasteners specified should be driven flush asshown in Figure 2.

Screw fasteners should be screwed as close aspossible to the stud corners to avoid deflection ofthe stud flange.

Fastener durabilityFasteners must have the appropriate level ofdurability required for the intended project. This is ofparticular importance in coastal areas, areas subjectto salt spray and other corrosive environments.Fasteners must be fully compatible with all othermaterials that they are in contact with to ensure thedurability and integrity of the assembly.Contact fastener manufacturers for more information.

Ensure the Scyon cavity trim butts up to the JHPVC vent strip. Do not insert the Scyon cavity triminto the JH PVC vent strip.

LayoutPlanning the layout of the Scyon cavity trim and theMatrix panels is an essential part of installation toensure a professional finish.

Datum lines should be set-up and used to ensurethe edges of the Scyon cavity trim and Matrix panelsare square. Datum lines can include the edges ofwindows, doors and building corners, see Figure 6.

PREPARATION

NOTEGenerally, external and internal corners haveadditional framing requirements. Refer to theexternal and internal corner details for moreinformation.

SCYON CAVITY TRIM INSTALLATIONGeneralThe Scyon cavity trim is installed vertically over thevapour permeable membrane to either timber ormetal stud wall frames. The Scyon cavity trim maybe installed either on or off stud, refer to framingsection for more information and Figures 4 and 5.

On-stud fixingFor off-stud fixing the Scyon cavity trim is installeddirectly to stud over the vapour permeablemembrane, see Figure 4. For fastener and studspacings, refer to Table 1.

Off-stud fixingThe Scyon cavity trim can be installed off-stud overthe vapour permeable membrane. It is importantthat horizontal supports (noggings) are installed at amaximum of 800mm vertical centres. A specifiedfastener is fixed at the intersection of every support,see Figure 5. For Scyon cavity trim and studspacings, refer to Table 1.

FASTENER FIXING OPTIONS

Matrix panel fastenersThere are four fixing options to fix the Matrix panelsto the Scyon cavity trim (also see Figures 19-22):

1. C25mm 16 gauge 304 stainless steel brad nails.

2. 2.8x30mm corrosion resistant fibre cement nails.

3. 25mm countersunk stainless steel screws.

4. 25mm wafer or pan head stainless steel screws.

NOTE: When using brad nails ensure that brad nailsare not used in high wind areas, see Table 1.

In all options, a continuous bead of James Hardiejoint sealant is applied to the Scyon cavity trim to fixthe back of the Matrix panel to the Scyon cavitytrim, see Figure 16.

For screw fasteners, a clearance hole must becreated using a 6mm masonry drill. For countersunk screws, the fastener must also becountersunk 2.5 to 3mm below the Matrix panel’ssurface, see Figure 21. The countersunk fastener isthan flushed finished with epoxy and then with JamesHardie base coat. Use only proven epoxies for thisapplication, i.e. Megapoxy P1 or Hilti CA 125. Wherethe temperature is below 15º, use Hilti CA 273.For exposed head screws a JH facade washer isrecommended to be inserted between the paneland the exposed head fastener, see Figure 22.

FIRE RATED WALLSScyon Matrix clad walls can achieve fire ratings of60/60/60 and 90/90/90 when constructed asspecified in the James Hardie fire and acousticallyrated walls design manual and construction of fireand acoustically rated walls technical specification.

Furthermore, as the Scyon Matrix cladding consistsof Scyon cavity trim installed over the wall frame,the fire and water resistant plasterboard must beinstalled behind the vapour permeable membraneand Scyon cavity trim. It must not be directlyinstalled behind the Matrix panels. The length of thefasteners fixing the Scyon cavity trim to the wallframe will need to take into account the thickness ofthe fire and water resistant plasterboard.

FINISHESGeneralRefer to the project specification for paintrequirements. Matrix cladding and exposed Scyoncavity trim must be painted within 3 months ofbeing fixed.

The rear of the Matrix panel must not be leftpermanently exposed to direct sunlight.

In order to seal cut edges or sanded patches twocoats of an appropriate primer should be applied atthe time of cutting or sanding compatible with finishcoating e.g. Dulux AcraPrime 501/1 (water based).

James Hardie recommends the application of twocoats minimum of a quality acrylic paint over thepre-primed Matrix panels and the exposed Scyoncavity trim in accordance with the paintmanufacturer’s specifications. Painting selection andspecifications is dependant on the paint chosen.

Coastal areasIn areas within 1km of a coastal area or corrosiveenvironment, the Matrix panels must be paintedimmediately after fixing sheets, to minimise build upof contamination on the heads of the fasteners, as itmay lead to fastener corrosion. Also refer tomaintenance requirements and fastener section formore information.

Refer to the paint and fastener manufacturer forfurther information, suitable products and details oftheir warranty.

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