New Zealand Building Code (NZBC) Clause E2 – External Moisture Section E2.3.3: It prevented the penetration of water that could have caused undue dampness or damage to building elements. Supa Board has been tested for water absorption and water permeability in accordance with New Zealand standard NZS

Health & Safety

WARNING: Supa Board contains fibre glass mat. DO NOT breathe in the excess dust when cutting sheets; the fibre glass dust may cause lung scarring. When using power tools during sheet cutting, wear an approved dust mask and safety goggles as recommended by the Australian Standards. A diamond blade wet saw will reduce the dust by a very considerable amount. Caution should be taken when using this type of machinery. A safety power box must be used to avoid electrocution.

Getting a Good Finish

Before installing Supa Board, selecting the right finish and texture coat system are part of the critical factors to be considered. In all cases the instructions from the paint manufacturers are to be followed. Work closely with the texture coat manufacturers and well-trained applicators. To enhance both the appearance and the performance of Supa Board, the following are to be considered:

A Straight Frame The final finish is dependent on the straightness of the frame. The frame can be checked and straightened if it is out of the tolerance.

Avoiding Large Unbroken Wall Area The plainness of a wall elevation can be broken by window and door openings, whereas in large unbroken wall elevations, joints can sometimes be visible. The sheet layout around opening is important.

Minimum Thickness of Texture Coat A minimum of 2mm thick texture coat helps to conceal joints. Heavier texture such as scratch coat can also help provide a monolithic finish.

Use of Low Gloss Finish & Light Coloured Paints A low floss finish will help diffuse glancing light and light coloured paint exposed to sun will last longer than dark coloured coating.

Durability & strength Supa Board is durable, flexible and tough with following bending strength (modulus or rupture):

When dry – approximately 17 MPa (7.5 mm thickness)

When wet – approximately 21 MPa (7.5 mm thickness)

Supa Board has also been tested for bending strength in the following conditions:

After immersion in warm water (at 60o C) for 56 days

After 25 soak (in 15o C water) and dry (at 60o C) cycles

All bending strength test results comply with AS/NZS 2908.2:2000

Fire Performance Supa Board has been tested for flammability and has demonstrated that it is non flammable.

Water Resistance Supa Board installed in accordance with this publication will meet the requirements of the following relevant sections of the building codes: Australian Building Codes Board (ABSB) Part F1 – Damp and Weatherproofing Section FP1.4: A roof and external wall (including openings around windows and doors) must prevent the penetration of water that could cause:

a. Unhealthy or dangerous conditions, or loss of amenity for occupants; and

b. Undue dampness or deterioration of building elements.

Board Installation

General Supa Board can be fixed to either a timber frame or a lightweight metal frame. The frame must comply with the local building regulations and the requirements of the brochure. Supa Board must be supported and fixed to the frame and must not be joined without fixing the frame. Maximum frame centres for fixing sheets to the frame is 600mm centre to centre. To provide sufficient support for screws or nails, a minimum stud width of 42mm (for timber) or 36mm (for a metal frame) is required. Where this is not possible, an additional stud will be required to ensure fasteners can be fixed at a minimum distance of 12mm from the sheet edge. Supa board recommends using Buildex(R) Fibre(R) Self-drilling screws. Refer to Buildex brochure for fixing instructions. The recommended screw/nail sizes are:

Steel frames: 30mm screws

Timber frames: 50mm screws or similar nails 50 – 60mm

The maximum stud spacing is:

600mm for 1200mm wide sheet

450mm for 900mm wide sheet

Page 6

Sheet Layout Supa Board (panel) should be fixed to framing vertically. Planning the sheet layout before fixing is important in order to minimize the number of sheet joints and material wastage. Avoid horizontal sheet layout where possible. Horizontal sheet layout is only recommended where the maximum depth of cladding is 1200mm or 900mm (one sheet width). Horizontal sheet installation is more suitable for applications such as fascias, spandrels, parapets etc.

Sheet installation Fasteners must be fixed at minimum of 12mm from the sheet edges and 50mm from the sheet corners. Fasteners must be fixed along the edge of the sheet and the distance between the centres of the fasteners must not exceed 200mm.

Screw

Framing & Fixing All studs and noggins must be checked with a log straight edge for line and face accuracy, to ensure the stud wall has a true and accurate outside face as any warping will be visible after paint or texture. A suggested tolerance should be less than 2mm per 500mm.

Timber The timber used should comply with AS1684.2 “Residential Timber Framed Construction” The timber used for house construction must have the level of durability appropriate for the relevant climate and expected service life and condition.

Timber frame thickness (stud width) at sheet joints must have a minimum of 42mm. Timber with less than 42mm wide must not be used at any sheet joint because of insufficient sheet landing width, and should provide double studs at sheet joints.

Page 8

If there is a supporting frame in the middle of the sheet, the fasteners should be fixed in the body of the sheet, and the distance between the centres of the fasteners must not exceed 300mm. Control joints should be installed where there is a significant structural moment expected. In general, if a continuous run of sheeting exceeds at 5.4m and at flooring level, it must be broken with control joint.

Vertical control joints They must be installed in the wall run over 5.4m. The control joints require a 6mm gap between sheets and the joint must be supported by double studs.

Horizontal control joints They must be located in walls at 3.6m maximum centres. They are also required at floor joint level and at garble ends.

Page 9

Metal Supa Board can be fixed directly to lightweight metal frame which complies with AS3623; however the metal frame should not exceed 1.6mm in thickness. The metal frame must have a minimum flange width of 36mm per sheet joints, as this will provide adequate support for fixing two sheet edges. Where narrow sections are used, provide double studs at the sheet joints. When fixing Supa Board to a rigid framing, always batten out using timber or light steel prior to fixing. Battens supporting the sheet joints must have a minimum face width of 45mm. Hot rolled steel structural sections must be battened out with timber or steel battens before sheets are fastened. The sheet must not fix directly to hot rolled steel frames.

Sheet Preparation Supa Board can easily be cut on site using a diamond tip power saw. All cutting operations must be carried out in open air or in a well ventilated area. Ensure a dusk collector or mask is used at all times. Note; Supa Board product will produce small particles when cutting, which will fall to the ground. Holes can be formed by drilling them around the perimeter of the sheet and removing them by punching out the centre by use of a hammer.

Components

Screws For light weight steel frames 0.75mm to 1.6mm thick

Nails Galvanised; 2.0mm x 30mm for softwood and 2.0mm x 25mm for hardwood. (Nails can be used on centre stud but not on edges)

Corner Beads Taped and Set corners – to satisfy coating manufacturer’s specification.

Starter Strips Starter Strip provides a straight edge to finish coating and protects sheet edges.

Timber Framing Use of timber framing must be in accordance with AS 1684 – “Residential timber-framed construction” and the framing manufacturer’s specifications.

Steel Framing Use of steel framing must be in accordance with AS 3623 – “Domestic metal framing” and the framing manufacturer’s specifications.

Panel Layout Panels must be laid across the joists and sheet end joints should be staggered.

Fixing Steel frames/ Timber frames: Supa Board recommends using Buildex FibreZIPS Self-frilling screws. Refer to Buildex brochure for fixing instructions. The recommended screw size is 50mm galvanized screw.
