It is an evolutionary product made in Raymond Terrace NSW at the original 1939 Masonite Factory. Massive investment in production upgrades, computerisation and painting facilities have been made since Weathertex s introduction as an evolved product in Weathertex is turning negatives into big positives. Who would have thought that an industrial factory would return massive carbon savings long before it is compulsory to do so. Weathertex proudly boasts its products have a negative carbon footprint. Weathertex puts sustainability and durability at the forefront of all our products. Made from environmentally sustainable Australian hardwood, Weathertex is an all natural product with 97% hardwood, 3% natural wax and no artificial additives, resins or glues. Weathertex Weatherboards and Architectural Panels are manufactured to comply with the requirements for Exterior Hardboard AS/NZS :Wet - Processed Fibreboard. Some Weathertex products are also AFS and PEFC certified. This technical specification covers the use of Weathertex products for buildings that fall within the scope of the NZBC Acceptable Solution E2/AS1.

PRODUCT LENGTH (mm) SUITED TO: CORNER SOAKERS 150 Primelok Primelok 200 WEATHERTEX ANODISED ALUMINIUM PAINTING Anodised aluminium products must be coated with a suitable etch primer prior to painting, then normal commercially available top coats are able to be applied. Please contact the paint manufacturer for advice with these coating systems. SURROUNDING MATERIALS Corrosion of aluminium may be exacerbated when contact is made with other metallic materials commonly used in construction. Iron and Steel Under humid conditions or areas close to the sea, the corrosion rate of aluminium may be accelerated when in contact with structural steel. To improve the performance of the aluminium product under these circumstances the steel should be coated. Non-ferrous metals Contact with copper and its alloys must also be avoided. Coating of these components is a satisfactory method of minimising this effect. Note: there are various timber products which have been treated with metallic compounds which may promote corrosion under this system. Check this before using. Non-metals Contact with fresh concrete, mortars, plasters and fibre cement product should be avoided. These materials can release traces of alkaline materials which can cause a rapid corrosive staining of the aluminium product. Damp or unseasoned timber may also cause a corrosive effect on the aluminium. This should be primed with a zinc chromate undercoat and sealed with a suitable top coat. Adhesives should contain less than 0.1% chlorides. Weathertex aluminium products have been anodised to provide a protective coating to the corrosive elements mentioned above. MAINTENANCE Standard maintenance of exposed anodised aluminium corners should include periodic cleaning on at least a six month interval. In an industrial or marine location this frequency should increase because of the more severe environment. The following cleaning method is recommended. Clean with a dilute solution of mild liquid detergent at room temperature. Use a soft bristle brush or cloth. Do not use abrasive tools or cleaners. After cleaning, rinse thoroughly with fresh water. Do not use strong solvent, acidic or alkaline cleaners. Where the use of solvent is required, such as cleaning paint spills, use Methylated Spirits only. Minimise the contact time as much as possible and rinse thoroughly with fresh water. STORAGE AND HANDLING Anodised aluminium products should be stored in a dry and flat position away from any potentially corrosive materials. Timber or soft bearers at a distance no more than one metre apart should be used to support the product. Prolonged exposure to moisture will promote corrosion. This should be avoided and if experienced, immediately correct. The products are subject to damage or could damage other materials they are brought in contact with. The edges and cut corners of the product may cause personal injury if brought into contact with the body. Wear glasses, gloves and protect skin where possible. When cutting use appropriate personal protective equipment such as eye protection and avoid air borne metal fragments. 3

All fasteners (nails and screws) must be galvanised or suitably coated to resist corrosion for external application. (Australian Standard AS 3566, Class 3 for screws). 2. Coastal locations can be very corrosive to fasteners, especially within distances of up to 500m from the sea. When installed in high corrosion zones, fasteners (nails and screws) must be made of materials appropriate to the desired life of the system and geographical location. Stainless Steel Nails and Class 4 Screws may be necessary in these zones. The advice of the fastener supplier should be sought. 3. The fasteners specified are minimum lengths required for each specific profile. If there is additional material between the Weathertex and the stud eg. packing, then the fastener length should be increased to provide the same fastener depth in the stud. See Cavity Fixing System Installation Instructions on Page 12. GUN NAILING MIN IMU M RECOMMENDATI ONS Gun nailing may be used as an alternative to specified hand driven nails. Generally, gun nails should have equivalent dimensions, head size, etc. to hand driven nails and must be galvanised or suitably coated for external use. Suitable nail guns for the installation of Weathertex with the nails below includes, but may not be limited to: DUO-FAST KD665A Coil Nailer STANLEY BOSTITCH N75C-1 (With dial a depth) PASLODE Impulse Compact Nailer B20544 MAX CN565S SENCO - SCN56 Supplier For Softwood Frames DUO-FAST STANLEY BOSTITCH PASLODE Gun Model C25-45-RGD C25-50-RGD AC45R250-GAL AC50R250-GAL B20443 D41580 Nail (Guide/Minimum) 50mm ring shank galvanised nail direct fix 75mm ring shank galvanised nail cavity fix 50mm ring shank galvanised nail direct fix 75mm ring shank galvanised nail cavity fix 50mm ring shank D-HEAD galvanised nail direct fix 75mm ring shank stainless steel nail cavity fix For Steel Frames ( mm for use in Geographic regions up to C2 only) Fixing Method Direct Fix Cavity Fix Timber Batten Method EPS Batten Method Cladding Selflok, Primelok, Architectural Panels Selflok, Primelok, Architectural Panels Selflok, Primelok, Architectural Panels Length Required 40mm 30mm 50mm Notes: 1. Installers using gun nailing should assure themselves that the appearance of the finished nailed Weathertex is suitable for the intended use. Generally, head sizes in excess of 6mm or T and D headshape nails may not produce a satisfactory finish on Selflok profiles or any other face fixed profiles eg. Weathergroove. 2. Fasteners MUST NOT be overdriven. This can reduce the holding capacity of the Weathertex. If the nailing depth cannot be adequately controlled when gun nailing, then it is preferable to under-drive and tap home with a hammer. 3. All fixings must be suitable for use on steel frames, for example hardened screw shank nails. If not using hardened screw shank nails, please consult nail manufacturer for the suitability of the nail chosen for steel frame application. 4. Nail fixings shall be flat or round-head type nails. 5. Lengths are the minimum required. 5

The sound transmission class can be increased to around STC by using fibreglass or insulating board beneath the internal lining. Further STC data can be obtained in the Weathertex and Fire Factsheet. CUTTING Weathertex products are easy to cut and shape with a normal hand or power saw. Weathertex may be stacked two or three high for multiple cutting. Primelok Weatherboards should be cut individually to protect the aligning spline. Where required, edges may be trimmed with a smoothing plane or sandpaper. Holes are easily drilled with high speed drills or clean cutter bits. STORAGE Weathertex products should be stored flat, under cover and on timber bearers spaced at maximum centres of 600mm. When storing keep the stack clear of the ground and cover with waterproof materials to prevent water staining. HEALTH AND SAFETY The normal health and safety precautions should be taken when working with wood panel products. Machine tools should be fitted with dust extractors and work areas kept clean. If dust levels exceed safe working levels the wearing of a dust mask and safety glasses is recommended. Storage and work areas should be adequately ventilated. 6

SITE AND FOUNDATION The site on which the building is situated must comply with the NZBC (New Zealand Building Code) Acceptable Solution E1/AS1 Water. Foundation design must comply with the requirements of NZS 3604 Timber Framed Buildings or be to a specific engineering design. The grade of adjacent finished ground must slope away from the building to avoid the possibility of water accumulating. Surface GROUND CLEARANCES The floor must have a minimum clearance to paved or unprotected ground as required by NZBC Acceptable Solution E2/AS1. Weathertex Weatherboards and Architectural Panels must overhang the bottom plate on a concrete slab by a minimum of 50mm. The bottom edge of Weathertex Weatherboards and Architectural Panels must be kept clear of paved surfaces by a minimum of 100mm and a minimum of 175mm above unprotected ground. MOISTURE MANAGEMENT It is the responsibility of the specifier to identify moisture related risks associated with any particular building design. Wall construction design must effectively manage moisture, considering 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. Walls shall include those provisions as required by the NZBC Acceptable Solution E2/AS1 (current edition) External Moisture. In addition all wall openings, penetrations, junctions, connections, window heads, sills and jambs must incorporate appropriate flashing for weatherproofing. The other materials, components and installation methods used to manage moisture in the walls, must comply with the requirements of relevant standards and the NZBC. WIND LOADING Weathertex Weatherboards and Architectural Panels are suitable for use in all Building Wind Zones (including and up to VH) in New Zealand as defined by NZS A specific design is required for all situations where a building falls in a specific design (SD) wind zone. Installations in specific design wind zones are outside the scope of this literature. 7

10 F RAMING Timber framing must comply with NZS 3604 for buildings or parts of buildings within the scope limitations of NZS Buildings or parts of buildings outside the scope of NZS 3604 must be to a specific design in accordance with NZS 3603 and AS/NZS Where specific design is required, the framing must be of at least equivalent stiffness to the framing provisions of NZS All timber framing sizes and set-out must comply with NZS 3604 and stud, noggings/dwangs centres as required by this specification. DIRECT FIX CONSTRUCTION METHOD The following framing must be provided for direct fix construction method: - Frames should be straight and true with studs at a maximum of 600mm centres for buildings located in NZS 3604 Building Wind Zones up to, and including 'High', and a maximum of 450mm centres for buildings located in NZS 3604 Building Wind Zone 'Very High' (Weathertex recommend 450mm centres maximum.) - Noggings must be provided at 750mm maximum centres (Architectural Panels). DRAINED AND VENTILATED CAVITY CONSTRUCTION METHOD The following framing must be provided for cavity construction method: ARCHITECTURAL PANELS - Frames should be straight and true with studs at a maximum of 600mm centres for buildings located in NZS 3604 Building Wind Zones up to, and including 'High', and a maximum of 450mm centres for buildings located in NZS 3604 Building Wind Zone 'Very High' and noggings provided at 750mm maximum centres. - An extra stud is required at internal corners. - Extra packers may be required at external corners. WEATHERBOARDS - Frames should be straight and true with studs at a maximum of 600mm centres in Very High Building Wind Zones. - An extra stud is required at internal corners. - Extra packers may be required at external corners. Steel framing must be to a specific design meeting the requirements of the NZBC. The minimum framing specification is C section studs and nogs of overall section size of 75mm web and 32mm flange. Steel thickness must be minimum 0.55mm. Studs must be at maximum 600mm centres. Metal frames must be erected in accordance with the manufacturer s recommendations. WEATHERTEX ON STEEL FRAMES Installing Weathertex onto a steel frame is generally similar to installing Weathertex on a timber frame. Weathertex supports both frame types and Weathertex s range of Weatherboards and Architectural Panels are supremely suited to installation on either timber of steel. There is however some differences which the installer must be aware of when installing Weathertex products onto a steel frame. The following information sheet outlines the technical information unique to steel frame installation. This includes: - The NZBC requirement of thermal breaks on steel frames - Specific fixings and fixing methods suitable for installing Weathertex on a steel frame for different wind levels THERMAL BREAKS Thermal Bridging Thermal bridging is the transfer of heat across a conductive path. This conductive path is created between the internal and external lining of a wall by a steel frame. Steel is a good conductor of heat and offers little to no resistance to its flow. The movement of heat across a steel frame leads to a reduction in the R-value of the overall wall system and thus means the building heats up excessively in summer and loses heat in winter. This movement of heat significantly reduces the efficiency of the building s heating and cooling systems. To address this issue, the NZBC introduced provisions for the inclusion of thermal breaks to be installed to interrupt thermal bridging. Construction with Thermal Breaks New Zealand Building Code (NZBC): Acceptable solution E3/AS1.1.4d requires a thermal break to be installed between the Weathertex external cladding and the metal framing members to separate both elements. Not only is it a NZBC requirement, the inclusion of a thermal break also increases the energy efficiency of the constructed building, which means less energy is required to maintain a comfortable climate within the home which reduces energy bills and the buildings environmental footprint. Weathertex recommends the following options as suitable thermal breaks to comply with the NZBC requirement for both cavity and direct fix construction systems. Consult fixing table for fixing requirements. 8

11 DIRECT FIX CONSTRUCTION Softwood Timber Battens Softwood timber battens are easily installed to provide a suitable thermal break between Weathertex and a steel frame. The softwood timber battens shall be 25mm thick and wide enough to cover the face of the frame. For example if 70x35 steel frame is chosen, the battens shall be 25x35mm at suitable length. Battens must be secured to all studs, noggings and the top and bottom plate. Breather membrane must be installed between the steel frame and the battens. Vapour permeable sarking is not suitable in this case. The breather membrane can be secured by the timber battens as they are installed along a wall. Final fixings will hold battens firmly in place but they must be temporarily fixed to the frame by gun nails at 600 centres before the cladding can be installed. To stop vermin and other material entering the cavity, the base of the cavity must be sealed using a cavity closer. A cavity closer must be installed at the base of the wall and above window heads and inter-storey flashings. The bottom of the battens is inserted into the cavity closer. Fix the cavity closer to the base plate at 300mm centres with 30 x 2.8 flat head nails. Butt-join cavity closer ends and ensure the closers are fixed in a straight, level line. It is important that the openings in the cavity closer are kept clear and unobstructed to allow free drainage and ventilation of the cavity. Once the wall has been battened out, Weathertex s standard fixing instructions shall be followed to install the cladding on the frame. Expanded polystyrene strips Expanded polystyrene strips are an alternative to softwood timber battens for a thermal break solution. Expanded polystyrene strips must be at least 12mm deep and wide enough to cover the face of the frame. For example if 70x35 steel frame is chosen, the battens shall be >12x35mm at suitable length. Battens must be secured to all studs, noggings and the top and bottom plate. Breather membrane must be installed between the steel frame and the battens. Vapour permeable sarking is not suitable in this case. The breather membrane must be held in place temporarily before the battens and the Weathertex are installed. Gun nails are suitable to fix the breather membrane to the frame. After fixing the breather membrane to the frame, the expanded polystyrene strips must be secured to all studs and noggings. Nails or screws cannot be used to secure expanded polystyrene strips to the frame. Instead, double-sided adhesive tape or construction adhesive is suitable to hold the strips in place on the frame. Final fixings will hold extruded polystyrene strips firmly in place. To stop vermin and other material entering the cavity, the base of the cavity must be sealed using a cavity closer. A cavity closer must be installed at the base of the wall and above window heads and inter-storey flashings. The bottom of the extruded polystyrene strips is inserted into the cavity closer. Fix the cavity closer to the base plate at 300mm centres with 30 x 2.8 flat head nails. Butt-join cavity closer ends and ensure the closers are fixed in a straight, level line. It is important that the openings in the cavity closer are kept clear and unobstructed to allow free drainage and ventilation of the cavity. Once the wall has had all thermal breaks installed, Weathertex s standard fixing instructions shall be followed to install the cladding on the frame. CAVITY FIX CONSTRUCTION To provide an acceptable thermal break and cavity solution the following system must be constructed. 30mm thick softwood timber battens are to be installed onto all studs and 12mm thick EPS battens are to be installed onto all noggings and top and bottom plates. Breather membrane must be installed between the steel frame and the battens. Vapour permeable sarking is not suitable in this case. The breather membrane can be secured by the timber battens as they are installed along a wall. Final fixings will hold battens firmly in place but they must be temporarily fixed to the frame by gun nails at 600 centres before the cladding can be installed. To stop vermin and other material entering the cavity, the base of the cavity must be sealed using a cavity closer. A cavity closer must be installed at the base of the wall and above window heads and inter-storey flashings. The bottom of the battens is inserted into the cavity closer. Fix the cavity closer to the base plate at 300mm centres with 30 x 2.8 flat head nails. Butt-join cavity closer ends and ensure the closers are fixed in a straight, level line. It is important that the openings in the cavity closer are kept clear and unobstructed to allow free drainage and ventilation of the cavity. Once the wall has been battened out, Weathertex s standard fixing instructions shall be followed to install the cladding on the frame. 9

12 CORNER TREATMENTS ALUMINIUM CORNERS Aluminium, like all metals, is subject to thermal expansion/contraction. As a guide it is recognised that aluminium moves by as much as 0.1% of its length over a temperature change of 30 degrees celsius. For this reason it is recommended that expansion gaps be used when working over lengths of greater than 6 metres. This also applies for ends which are to brought to a rigid stop. Internal and external angles can be fixed with hot dipped galvanised flat head nails and then permanently fixed by the Weathertex fasteners specified for each profile penetrating the flashing wings. It is best to leave a small expansion gap (1 to 2mm) between the Weathertex and Aluminium Corner, which can be filled with a flexible sealant such as Sikaflex Pro 2HP or Fuller Super Seal HPR25 if required. Always wear safety glasses when cutting aluminium corners. Notes: Flashing from a width of 50mm from the apex of all corners must be installed beneath all corners prior to installing Weathertex Aluminium Corners. ARCHITECTURAL PANELS - Small Internal and External Aluminium Corners Aluminium Internal Corner Aluminium External Corner WEATHERBOARDS - Large Internal and External Aluminium Corners Aluminium Internal Corner Aluminium External Corner TIMBER BOX CORNERS External: Weatherboards and Architectural Panels may be butted up to 50mm x 25mm finish size or rebated primed timber stops. Prime any cut ends. Install waterproof flashing around corner studs prior to fixing timber stops. When joining Weatherboards and Architectural Panels up to other materials (for example brickwork) provide 3mm clearance. Waterproof flashing Internal: Butt Weatherboards and Architectural Panels up to 25mm x 25mm finish size primed timber stops. Prime any cut ends with solvent-based wood primer. Alternatively, Weatherboard and Architectural Panels ends may be scribed and cut to fit the planks on the adjoining wall. Timber stop Rebated Timber stop CORNER SOAKERS Pre-formed Metal corners can only be used with Weathertex Primelok Classic, Federation and Shadowood profiles. Splay out adjoining Weatherboard ends and butt together at corner. Fit the pre-formed metal corner by locating the bottom flange under the planks. Push upwards until the corner is flush with the lower plank edge. Fasten with one nail through the hole at the top. - When jointing Weathertex Weatherboards up to other materials (for example brickwork) provide a 3mm clearance. It is the responsibility of the designer to detail this junction to ensure it remains weathertight. 10

13 PAINTING AND MAINTENANCE ALWAYS PAINT WEATHERTEX WEATHERBOARDS, ARCHITECTURAL PANELS AND WEATHERTEX SHINGLES WITHIN 60 DAYS OF FIXING. FAILURE TO OBSERVE THIS REQUIREMENT MAY RESULT IN POOR ADHESION OF THE TOP COAT AND MAY VOID WARRANTY. PRIMING Sawn edges of Weatherboards and Architectural Panels which are exposed, butt joined on studs or meet other materials such as timber stops must be primed with solvent-based or acrylic tannin resistant wood primer. A sprayable primer is the most efficient method. To comply with good building practice, timber mouldings, including corner stops and trims, should be primed with exterior, solventbased or acrylic tannin resistant wood primer before installation. Due to the possibility of prolonged exposure to cold and moisture, the curing of the paint applied to Weathertex may at times be adversely affected. In such cases, the ability of the paint to suitably protect the Weathertex and to provide optimum durability can be reduced. In order to enhance the durability of Weathertex in the harsh New Zealand climate, before top coating, a liberal coat of solvent based undercoat (not primer) must be applied to the edges of Weathertex. This shall include: the horizontal drip edge including the whole bottom edge and up to 50mm up the front and back faces of the Weathertex and the vertical and horizontal areas where the Weathertex comes to a join or terminates at the junction with other materials. After allowing adequate time for curing of the undercoat, apply the top coat in accordance with the manufacturer s recommendation. PAINT COLOUR Paint colour can have an effect on the performance of Weathertex products. As Weathertex is a timber product, its dimensions will change with changes in moisture content. Dark paint colours can allow surfaces in warmer climates to become very hot leading to loss of moisture and subsequent shrinkage of the Weatherboard. Plastic joint trimmers can also distort at high temperatures. Light paint colours will lead to better thermal efficiency of the building and minimise problems due to moisture change. Movement of Weatherboards due to moisture changes may cause butt joins to open up after installation, particularly on longer wall lengths in full sun that are painted in darker colours. To minimise the degree of movement that may occur, Weathertex recommends painting your Weathertex Weatherboards and Architectural Panels with a colour which has a Light Reflectance Value (LRV) of greater than or equal to 25%. (Refer to paint manufacturer for details on LRV). When using concealed joint trimmers lighter paint colours should be used. PREPARATION Surfaces should be free from dirt, dust or grease. Set fasteners flush with the surface and where necessary fill any holes with proprietary filler. Lightly sand any nibs or blemishes which have occurred during fixing. PAINTING The primed surface of Weatherboards and Architectural Panels are suitable for the application of exterior grade 100% acrylic or solvent-based paint systems. Unprimed products should be painted with an exterior 100% acrylic paint which is suitable for direct application to timber. Light colour paints should be tannin blocking. The paint manufacturer s recommendations on paint suitability, mixing and application, should also be followed. For Acrylic and Solvent-based finishes follow manufacturers instructions. MAINTENANCE Regularly wash the painted surface with water to remove dirt and grime and to improve the performance of the coating. Generally, exterior surface coatings deteriorate by chalking rather than flaking. When repainting becomes necessary and the surface is unbroken, wash down with water. Remove all loose chalk, dirt and dust by sanding, and dust off. Make good any defects and fill where necessary. Apply a minimum of two coats of paint in accordance with the paint manufacturer s recommendations. 11

14 P REPARATI ON ARCHI TECTURAL PANELS - WEATHERGROOV E For general framing and construction details refer General Requirements of this specification. Frames should be straight and true and provide support for the Weathertex at 600mm maximum centres. Plan sheet layout with long edges vertical. If the vertical joints are located over studs, provide frame support for all sheet edges. If the vertical joints are to be formed between studs, then sheet edges must be supported in rigid H section mouldings over nogging at 750mm maximum centres. Establish a horizontal datum or base line 50mm below the bottom plate and mark with nails and string line. GENERAL PREPARATION BUILDING WRAP Building wraps must comply with E2/AS1 and be fixed in accordance with E2/AS1, NZS 3604 and the building wrap manufacturer s recommendations. Specifically, attention must be paid to ensure that the building wrap shall: a) Be run horizontally, b) Have upper sheets lapped over lower sheets to ensure that direction of laps will allow water to be shed to outside of the building wrap, c) Be lapped not less than 100mm at horizontal joints, d) Be lapped not less than 150mm over studs at vertical joints, and e) Be added as a second layer over head flashings as shown in E2/AS1. Unlined gables and walls must incorporate a rigid sheathing or an air barrier which meets the requirements of NZBC Acceptable Solution E2/AS1. Non-rigid air barriers must have an air resistance of 0.1 MN s/m 3. Where rigid sheathings are used, the fixing length must be increased by a minimum of the thickness of the sheathing. In cavity installations where studs are at greater than 450mm centres, a building wrap support must be installed over the building wrap between the cavity battens at maximum 300mm centres. Building wrap support shall be either polypropylene strap, 75mm galvanised mesh, galvanised wire, or additional vertical battens for securing the building wrap in place and preventing bulging of the bulk insulation into the drainage cavity. (Note: mesh and wire galvanising must comply with AS/NZS 4534.) 12 CAVITY BATTENS Buildings with a risk score of 7 20 calculated in accordance with NZBC Acceptable Solution E2/AS1 require Weathertex Weatherboards and Architectural Panels to be installed on a cavity (except for Millwood and Old Colonial profiles which must always be installed on a cavity. Cavity battens provide separation between the wall frame and the cladding and are considered to be a packer in this specification. Vertical timber cavity battens must be minimum H3.1 treated in accordance with NZS 3640 to comply with the durability requirements of B2/AS1. Cavity battens must comply with E2/AS1 and be: - A minimum of 18mm thick; and, - As a minimum as wide as the width of the studs; and, - Fixed to the studs using 40mm x 2.8mm galvanised nails at 800mm centres maximum prior to fixing cladding. (This will assist in maintaining them on the frame and keeping them straight). - Also fixed with the cladding fasteners to the main stud frame through the building wrap. Cavity spacers must be installed where required to support Weathertex sheets at fixing points between vertical cavity battens. Cavity spacers must comply with E2/AS1 and be: - A maximum of 100mm long; and, - Installed on a 5 slope; and, - Installed a minimum of 50mm clear of vertical battens and other cavity spacers. Cavity battens or spacers must not be located closer than 100mm to the edge of a window or door joinery opening. Where wall penetrations through the Weathertex cavity system are wider than the cavity batten spacing, allowance must be made for airflow between adjacent cavities. A minimum 10mm gap must be left between the bottom of the vertical cavity batten and the flashing to the opening. Fixing CAVITY CLOSER A cavity closer strip must be installed in the ventilated cavity construction method at the base of wall/floor and above window head and inter-storey flashings. It is important that the openings in the cavity closer strip are kept clear and unobstructed to allow free drainage and ventilation of cavities. The cavity closer shall: a) Provide holes or slots between 3mm and 5mm, b) Provide an area of opening of 1000mm 2 per lineal metre of wall, and c) Be positioned to allow a minimum drip edge to the wall cladding of: i) 10mm at the base of walls, and ii) 15mm above window head flashings. d) Be manufactured from PVC, aluminium or stainless steel. Height to suit Holes or slots between 3mm and 5mm to provide ventilation area of 1000mm 2 per metre length Cavity depth Note: To be used in drained cavities at the base of walls and above window head and inter-storey flashings.

16 JOINING USING TRADITIONAL JOINERS Form joins between Weatherboard ends using joiners selected to suit the particular product. Refer to Accessories. To avoid white lines either side of the joiner after product shrinkage, it is advisable to pre paint joiner insert ends with the desired top coat prior to installation. Stagger joins randomly throughout the wall. Joins should be formed midway between the studs. When fitting Weatherboards, bring the ends into moderate contact with the splayed edges or nibs within the joiner. Do not force ends tightly together. Simply cut joiners to fit at heads, sills and eaves. Notes: 1) On first row of Weathertex Rusticated remove leg gauge from back of joiner. 2) To fit joiners to cut ends of Primelok Weatherboards it is necessary to trim back the plastic spline. Joiner positioned midway between stud CONCEALED JOINERS When using the concealed joiner the following instructions MUST be followed: 1. Any cut end must be primed with a solvent-based exterior wood primer or an acrylic tannin resistant wood primer. 2. Insert the primed butt edge of the Weatherboard into the concealed joiner, resting the bottom edge on the base and locking into position under the top flange. The edge of the Weatherboard should be in moderate contact with the centre nibs within the joiner. Do not force ends tightly together. The top flange will be hidden by the overlap of the board. 3. Insert the primed edge of the next Weatherboard into the other side of the joiner against the centre nibs. A 6mm gap will be left when both ends are in contact with the centre nibs. 4. Fasten the Weatherboard to the wall at each stud in accordance with product requirements. 5. Using a caulking gun, run a line of quality, flexible, paintable acrylic sealant up the length of the concealed joiner. Always follow the sealant manufacturer's application instructions. 6. After drying, use a sharp blade to remove the excess sealant so the join is clean and flush with the Weatherboards. Notes: 1) When installing Primelok Weatherboards it may be necessary to trim back the plastic spline to fit joiners. Step 2 Step 3 Step 4 Step 5 Step 6 As a natural timber product, Weathertex may experience slight expansion and contraction with changes in its moisture content. This dimensional change can be apparent at plank joins, particularly where concealed joiners are used. While a slight opening of the joins is normal and will not jeopardise the performance of the joint to resist moisture ingress, it may not be aesthetically suitable in some cases. As an alternative, the following options may be of personal preference: 1. The use of a full H-style joiner. 2. Utilising a cover strip made of thin metallic materials such as aluminium in conjunction with a Weathertex concealed joiner. This can be held in place by a clip which hooks over the top of the bottom board and under the bottom of the overlapping board. This can either be installed during original fixing or after installation depending upon the situation. Where the cover strip cannot be hooked over the top of the board under the overlapping board then the cover strip may be attached by small non structural fixings to one of the Weathertex surfaces to the join. By attaching to one surface only, the Weathertex will be able to expand and contract without damaging the join. 14

Use 30mm x 2.5mm galvanised flat head nails for timber frames or No. 8 x 12mm pan head self-drilling screws for metal. Screws should be coated to resist corrosion. Space fasteners at 300mm centres along the strips. Butt join starter strip ends together and ensure the strips are fixed in a straight, level line. First Row: Position the first Weatherboard so that the spline locks over the starter strip. Press the Weatherboard down into the strip and fasten along the top edge of the board to every stud. Keep fasteners 15mm from the top edge. Continue fixing the first row and position joiner over adjoining Weatherboard ends and between the starter strips.to fit join to cut ends, trim back the spline at the back of the Weatherboard using a hacksaw or sharp knife. Successive Rows: Simply position each Weatherboard so that the spline locks over the splayed top edge on the preceding row. Press the Weatherboard down and fix along the top edge at every stud. Keep fasteners 15mm from the top edge. Check rows for level. Fasteners: Nail Weatherboards to timber frames with 50mm x 2.8mm galvanised flat head nails. Fix with one fastener at each stud and at all Weatherboard row ends. Commence fixing at one end of the Weatherboard and work along the edge. Alternatively, start midway along the Weatherboard and work outwards towards ends. Keep fasteners 15mm down from the top edge so that they will be hidden by the overlapping Weatherboard.

Successive Rows: Rest the rebated edge of Selflok Weatherboards on the row below. The shiplap join provides a 20mm overlap. Apply firm pressure to ensure adequate locking prior to fastening. Flathead Nail Nail Weatherboards to timber frames with hot-dip galvanised 75mm x 3.15mm flat head nails. Fix with two fasteners at each stud. Keep fasteners 12mm minimum from ends. Fasteners are to be placed 30mm up from bottom edge and 170mm up from bottom edge. DO NOT NAIL THROUGH SHIPLAP OR MILLED SECTIONS OF SELFLOK WEATHERBOARDS. Drive nails flush with the plank surface. VERTICAL FIXING Weathertex Selflok Weatherboards can be installed vertically to achieve the appearance of vertical lines. This appearance is usually provided by installing Weathertex Weathergroove, however, in some cases vertically installed Selflok Weatherboards may be preferable, such as where the weight of Weathergroove prevents easy handling. To fix Selflok Weatherboards vertically, noggins must be installed at maximum 600 mm centres. This provides a basis for fixings which, like when installing Selflok Weatherboards horizontally, must be provided at maximum 600 mm centres along each plank. Once the frame is established, Selflok Weatherboards must be fixed as per current fixing instructions for installing Selflok Weatherboards horizontally. If vertically installed Selflok Weatherboards are to be vertically joined, this must be achieved using Weathertex Z-flashing following the applicable instructions in the current Installation Guide. 15

18 I N S TALLATI ON W EATHERGROOV E CAVIT Y FIX Preparation: For general framing and construction details refer to General Requirements. Plan sheet layout with long edges vertical. If the vertical joins are to be formed between studs, then sheet edges must be supported with a Weathergroove Joiner over noggings at 750mm maximum centres. Establish a horizontal datum or base line at least 6mm below the base of the frame and mark with nails and string line. Fixing detail for Weathergroove: 1. Stud spacing is maximum 600mm centres. 2. Nails are 75mm x 2.8mm galvanised Weathertex nails (hand driven) or 75mm x 2.5mm ring-shanked, flat-head, galvanised gun nails (Duo-fast C25-45-RGD or equivalent). 3. Nailing detail in each corner of each sheet as shown. Nailing shall be no closer than 12mm from the sheet edges and must not be in the grooves of grooved sheets. 4. Off-stud joins are made using the relevant joiner over noggings at maximum 750mm centres. 5. Do not nail through the groove. Joining: VERTICAL JOINS May be formed using Weathergroove Joiner as specified in Accessories. This joiner will provide the necessary clearance to accommodate movement. Weathergroove has unique rebated edges for joining with the Weathergroove Joiner, the exposed surface of which are the same width as the grooves in the sheet. Joins may occur over studs or between studs to combine with the sheet grooves and maintain a regular vertical Weatherboard effect. Note: Grooves in Weathergroove are omitted for clarity of drawing. 45mm min Vapour Permeable Sarking 12mm HORIZONTAL JOINS USING ALUMINIUM FLASHING For horizontal joins, use the Aluminium Z Flashing.
