1 Introduction

& Scope Cortex is a solid timber weatherboard cladding system with a full factory applied top coat finish; it evolves this traditional product through the addition of new detailing and fixing methods. The Cortex system comes complete with all accessories including corner extrusions, scribers, cavity closers and flashings to make specification, building, and use a breeze. The Cortex 100% factory finished weatherboard Acrylic Coating System™ (ACS) delivers a consistent 120 micron ‘dry’ film thickness to the exposed surfaces of each board. This ensures each board delivers lasting performance across it’s lifespan. The ACS finish delivers a good looking, smooth finish that manual application can’t match.

Specifiers This manual is designed to provide all the information required for the planning and specifying process. Please ensure that the project you are planning falls within the scope of this manual and don’t hesitate to contact Cortex if you have any queries.

Builders & Installers This manual will provide all the information necessary for correct installation of the Cortex cladding system. The characteristics of the pre-finished board require careful handling and a range of proprietary fixings and flashings to be used, therefore we urge you to adhere to the specified installation sequence to ensure correct installation. Please contact Cortex if you have any queries. The Cortex Technical Manual is available for download from our website; www.cortexcladding.co.nz. Please ensure that you have the most up-to-date manual. If you are unsure, please check the website or call us on 0800 CORTEX.

1.1 Scope Please Note: This manual only covers the installation of the Cortex System on a drained and vented cavity. Cortex has been designed to be specified for domestic timber framed and light commercial buildings that fall within the scope of NZS 3604 and NZBC Acceptable Solution E2/AS1. The Cortex System is a cladding solution with corner boxing, scribers, flashings, and concealed fixing system, and should be specified and installed according to the details in this technical manual. Due to the pre-finished nature of the product only Cortex specified parts and accessories are to be used with the system, replacement or use of non-cortex flashings and accessories will invalidate the warranty.

2 Design &

Specification 2.1 Compliance The Cortex System has been successfully tested to the requirements of E2/VM1 and meets the performance requirements of the NZBC E2/AS1. This test was conducted by an IASNZ accredited testing laboratory.

2.2 Responsibility These specifications are specific to the installation of the Cortex System as a complete cladding solution and must be read in conjunction with the accompanying installation details and CAD files. The specifier must apply this specification to each individual project, ensuring that the details in this specification are suitable for the intended application and that additional detailing and specific designs are produced where required. The certified Cortex installer will install the system according to the details provided in this specification. For situations where details are not provided, please refer to NZBC E2/AS1.

2.3 Wind Loading The Cortex System may be used as exterior cladding in NZS 3604 type constructions for all wind zones up to and including “Very High”. The E2/VM1 weather-tightness testing verifies the systems performance up to a design differential ultimate limit state wind pressure of 2.5 kPa. The structural design of buildings situated in areas with a design wind speed of greater than 50 m/s (Very High) require specific engineering design. This also applies to window joinery.

2.4 Paint Selection The Cortex weatherboards are pre-finished with our factory applied Acrylic Coating System™ (ACS). Pre-finishing does not mean restrictions in choice; the entire Resene colour range is available from which to choose a suitable shade. However, to ensure that the coating will last we recommend that the colour chosen has a Light Reflectance Value (LRV) between 40-100%. If a colour with a lower LRV is specified, the durability of the coating cannot be guaranteed by Cortex and the warranty would not apply. A sample of the specified colour will be sent to the customer for final sign-off three weeks from production. For guidance on safe, durable colours please contact Cortex or visit us at www.cortexcladding.co.nz for further details.

1.2 Details All key installation details are provided at the end of this manual. These can also be downloaded directly from www.cortexcladding.co.nz. Please ensure that you are using the most up-to-date details. If you are unsure, please check our website or give us a call on 0800 CORTEX.

3 Installation Sequence Cortex is a 100% pre-finished weatherboard system; therefore, the installation sequence is important to retain the ultimate quality of the finish. An installation checklist is included (below) which refers to sections in the manual with detailed information about the specific area. This section should be read as a sequence before any installation is started. The Cortex Pre-finished Weatherboard System is to be installed by accredited Cortex Installers (refer to section 3.1). The recommended installation sequence is listed in the checklist below. Please note: Prior to the installation of the Cortex System; Framing, Building Wrap, Joinery, Roofs and Soffits must be installed by other contractor or builder.

3.1.1 The Installation Service The Cortex System is a fully integrated cladding solution that manages the process from specification to completion, including the installation. Cortex is installed by a certified team that is trained to install the Cortex System according to the specifications and guidelines in this specification. For more information about the installation service, please contact Cortex directly or visit our website.

3.1.2 Transportation of Pre-Finished Boards & Accessories All Cortex weatherboards are transported in a specially designed packaging system. This ensures that the pre-finished paint surface is protected from any potential damage during transit. To unload the weatherboards from the truck, use a mechanical lifting device or unload the package containing the board by hand. Do not tip the boards from the truck.

3.1.3 Storage on-site The boards should be kept in their original packaging on-site until the time of installation; the boards should only be removed from their packaging when they are being installed. When stored the Cortex pre-finished boards should be protected from unnecessary exposure to rain and sun. It is recommended that the board packages are stored under cover.

3.1.4 Handling of Pre-Finished Boards & Accessories The packaging will, in addition to the pre-finished boards, also contain the pre-finished corner caps, head flashings and scribers. Care must be taken when handling the pre-finished material to avoid any damage to the surfaces. Carry boards with their long section vertical to avoid bending of the board. Do not place the board with the pre-finished face down, and do not stack the boards on top of each other as this can cause paint blocking. Never use a hammer in contact with the pre-finished exposed surface.

3.2 Framing This specification only covers the use of timber-framed buildings. Other framing materials are outside the scope of the Cortex Technical Specification Manual. All framing must comply with the requirements of NZS 3604 Timber Framed Buildings. Specifically; The framing must be straight and true and within the ff tolerances allowed by Table 2.1 of NZS 3604 The moisture content of the framing must not exceed 20% ff

and studs, nogs/dwangs centred as required for cavity construction. a 7.5mm minimum clearance between the reveal or window frame and the trimmed opening. 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 1170. Where specific design is required, the framing must be of at least equivalent stiffness to the framing provisions of NZS 3604. In all cases studs must be at maximum 600 mm centres and dwangs must be fitted flush between the studs at maximum 800 mm centres.

3.3 Building Wrap Building Wrap compliant with the NZBC Acceptable Solution E2/AS1 must be installed to the outer face of the wall framing. A wall wrap (including building papers and synthetic wall wraps) as per Table 23 Cavity Wall are suitable for use with the Cortex System. The building wrap must be fixed in accordance with E2/AS1and the wrap manufacturer’s recommendations: Run the building wrap horizontally and continuously around ff corners, do not join material around corners. Install the wrap taut and without any wrinkles. Have upper sheets lapped over lower sheets to ensure that ff direction of laps will allow water to be shed to the outside of the building wrap. Overlap the wrap with a minimum of 75 mm at horizontal ff joints. Overlap the wrap with a minimum of 150 mm over studs at ff vertical joints. Fix wrap according to manufacturer’s specification. ff

ff Dress wrap into all framed openings, including window, door, and meter box openings. Apply a compatible flexible flashing tape around the window and door joinery opening in accordance with the requirements of E2/AS1 and the manufacturer’s instructions.

3.4 Drained & Vented Cavity Please note: The Cortex System is currently only to be specified with a drained and vented cavity.

3.4.1 Cavity Design & Material Materials

Fixings/Fasteners

Cortex 20mm Cavity Batten

Nail

Cortex Cavity Closer

8Gx50mm self tapping screw

A drained and vented cavity is created by fixing the Cortex Cavity Batten over the framing in accordance with the requirements of the E2/AS1. The cavity is vermin proofed using the Cortex Cavity Closer which has a minimum ventilation area of 1000mm2 per lineal metre.

ff The cavity must be drained and open to the exterior at the bottom of cavities such as at the bottom of the second storey junction and at the top of windows, doors, meter boxes and other penetrations. Where penetrations of the wall cladding are wider than the ff cavity batten spacing, allowance shall be made for air flow between adjacent cavities by leaving a minimum gap of 10 mm between the bottom of the vertical cavity batten and the flashing at the opening.

3.4.2 Cavity Closer Installation (Critical Detail) The Cortex Cavity Closer is specially designed to interact with the Cortex Rear Bracket and also aligns the system. The bottom Weatherboard and Rear Bracket assembly of the wall rests on the cavity closer. Install the cavity closer before installing the cavity battens and this makes alignment of the cavity closer easier. It is therefore imperative that the cavity closer is installed in level, to ensure a level and true installation of the weatherboards. A laser level should be used to align the cavity closer. Align the cavity closer to provide a minimum of 50mm ff overhang of the bottom weatherboard to the interior floor. Where possible position so that multiples of the 110mm pitch finish at the soffit. Terminate the cavity closer 25mm from either side of a corner ff (both internal and external) to allow sufficient room for corner flashings. The ventilation holes on the cavity closer must be kept clear ff and unobstructed to allow free drainage and ventilation of cavities.

Refer to installation detail C-03 Cladding to Ground

3.4.3 Cavity Batten Installation Please Note: The Cortex Cavity Closer, female part of Cortex 2-part Head flashing and female part of Material Transition Cap must be installed before installing the cavity battens. ff Ensure that the cavity closer and the female part of Cortex 2-part Head Flashing and the female part of Material Transition Cap are installed prior to installing the cavity battens. Fix Cortex Cavity Batten onto all vertical framing members ff over the building wrap. Battens are to be fixed by the cladding fixings which penetrate the wall framing. Battens will therefore need only temporary fixing until the cladding is fixed. When the cavity battens are installed at greater than 450 mm ff centres, the building wrap must be supported between the battens to prevent the wrap bulging into the cavity space when bulk insulation is installed in the wall frame cavity. Fix vertical cavity battens past the ends of the head flashings ff to form stop ends for the flashings. There must be no continuous horizontal battens below ff windows.

The concealed fixing system is unique to Cortex and eliminates any exposed penetrations of the pre-finished board ensuring that the finish retains its integrity. The screws and brackets combine to offer better board-toboard assembly and installation, whilst the 300mm spaced diamond fixing pattern dramatically increases strength and wind resistance over existing nailed systems. Pre-assemble the Rear Brackets to the pre-machined weatherboard using a 6Gx25mm Gypsum Screw. Position the rear brackets to be centred between studs, it is recommended to use a story stick to simplify the process. When cutting the boards to length, ensure that they are cut to the correct alignment groove on the female corner extrusion. End seal all cut ends with cortex approved wood primer.

Refer to installation details C-04 External Corners or C-05 Internal Corners Use the Cortex Alignment Tool to ensure that each board is installed with a consistent overlap and a board pitch of 110mm. Push the tool hard up against the base of the top weatherboard and adjust the new board to suit. Care must be taken in properly spacing the boards as any discrepancies will interfere with the pre-made Cortex Timber Scriber. Once the board is in place, fasten the top of the new weatherboard to the stud through the cavity batten with an 8Gx50mm Self Tapping Screw. Pre-drilling of the screw holes is recommended. The fastener should be placed at least 10mm in from the edge of the board to avoid splitting.

Fix the weatherboard in full wall lengths where possible. Where full wall lengths are , commit vertical joints only over a stud to ensure a stable joint. The joint is secured with the Cortex Vertical Joint Strip; a polypropylene barbed joint strip that joins the ends of the boards to protect against moisture ingress. This will require two rear brackets on either side of the joint to provide stability and strength. The vertical joint strip fits into a pre-machined slot on the edge of the weatherboards. The required number of boards with

pre-machined slots will be supplied with each job lot. The ends are pre-finished and do not require any further edge seal. Ensure that these are identified and chosen for the vertical joint installation. Create a sub-assembly by inserting the Cortex Vertical Joint ff Strip into the slot in one board and seal with the specified sealant. Assemble a rear bracket to the board, positioned as close to the stud as possible. Install the board sub-assembly on the wall and fasten the ff

assembly into place by firmly tapping the extrusion together. Ensure that the scriber is adjusted into place. This is best achieved by starting at the base and working upwards. The male extrusion is pre-finished and must be handled ff with care. When tapping into place use only a rubber mallet. The extrusion is designed to be able to absorb any inconsistencies in the wall/frame; the barbs on the male part allow you to tap the extrusion until a straight assembly is achieved.

4 Maintenance The Cortex System is designed for low maintenance. If cared for properly, it will stay looking great and protect your home for a long time. Please follow the instructions below. Please note that regular cleaning, according to these specifications, is required to maintain the Cortex Coating Warranty. The Cortex weatherboards and accessories must be washed at least annually, in salt laden environments cleaning must be carried out at least 4 times per year. This cleaning will remove salt deposits and contaminants that can attack the paint film and cause premature breakdown of the ACS.

completion of the building works.

4.1 Washing

For the repairs, sand to a smooth even surface, not a rough cut please, apply a coat of SXLÂ primer working it into the grain with a brush or if sprayed, roller it into the grain, leave as long as possible and then apply ModoglazeÂ undercoat by the same method.

Cleaning your house will help maintain its good look for longer. However, it is very important that the cleaning is done to the Cortex & Resene specification as incorrect cleaning can damage the painted surface and decrease the life span of the protective finish. Regular washing of your home is recommended to maintain the fresh appearance of the paint work. The Cortex weatherboard and accessories must be washed at least annually, in salt laden environments cleaning must be carried out at least 4 times per year. This cleaning will remove salt deposits and contaminants that can attack the paint film and cause premature breakdown of the ACS. This prevents airborne contaminants, including salt deposits which can attack the surface and cause premature breakdown, from settling on the paint film. Moss and lichen can also penetrate the surface of the film, while mould growth can destroy the chemical entity of the resin system that holds the paint system together. The presence of moss, mould and lichen will retain moisture on the painted surface, promoting further growth of these organisms and increasing the risk of damage to the coating. Removal using the appropriate washing procedure will increase the life of the coating and maintain the aesthetic properties of the paint finish.

Avoid letting the run off wash into the storm water system as most detergents have a negative effect on fish life.

4.2 Touch-up Painting A small test pot with the chosen house colour is provided for touch-up painting. Attend to any areas where the pre-finished paint film may have been broken. Ensure that the surface you are painting on is clean and dry before application.

For bare timber exposed that requires filler, apply SXL to the bare area, use exterior grade filler, sand smooth, apply two coats of Modoglaze, allowing it to dry between coats.

4.3 Re-Paint Cortex Pre-Finished Weatherboards are covered by a 10 year warranty conditional on correct maintenance and colour selection as specified in this document. After this period it is recommended that the house is re-painted. Prepare the surface as to the paint manufacturerâ&#x20AC;&#x2122;s specification and re-paint. We recommend colours with an LRV over 40% for optimum longevity and performance. The pre-finished surface can be re-painted in another colour at any point as this will not destroy or impact on the pre-finished surface.

4.4 Replacement of Damaged Weatherboards

For an instant fresh appearance, wash down the home with Resene Paint Prep and House wash diluted as recommended with water. Apply the diluted solution with a soft broom. Wash off with copious amounts of fresh water.

The Cortex Cladding System is designed for disassembly and can, if needed be taken apart without damaging the integrity of the system.

Never use a high-pressure sprayer/hose on your painted surfaces.

If a weatherboard for some reason gets damaged the corner extrusion can be un-clipped and the affected weatherboards replaced.

If you are planning to wash down a freshly painted surface, wait at least four weeks from completion of the painting job to give the paint time to fully cure. The Cortex weatherboards will be installed fully cured and can, if needed, be washed down on

Any repair work must be done by a certified Cortex Installer to ensure the validity of the warranty. Please contact Cortex directly if any replacements are needed.

Alternative installation of the Window Cavity Closer Depending on the location of the weatherboard in relation to the head flashing, a gap may be created. To effectively seal this gap, the cavity closer can be installed backwards. This method also eliminates teh need of a additional cant strip. Cortex™ Window Cavity Closer turned backwards to close gap between weatherboard and cavity batten. No cant strip is needed in this case.

The Cortex™ Head Flashing has been tested and passed the requirements of the E2/VM1.
