TOOLS
RECOMMENDED TOOLS TO INSTALL SLATTED CLADDING
Standard woodworking tools can be used when working with Our Slatted Cladding.
If you are unsure of how to use any tool, please consult the tool’s
manufacturer’s user manual.
- Circular Saw – we recommend a 60T+ Aluminium / laminate multipurpose blade to achieve the cleanest cuts.
- Mitre Saw extremely useful
- Jig Saw
- Hand Drill
- 3mm and countersink drill bits (SmartBit countersink tool available)
- Tape Measure
- Set Square
- String line
- Spirit Level
- Protective eyewear and relevant Personal Protection Equipment (PPE)
- Pencil
COLOURS AND EFFECTS
- Our Composite Cladding is available in 3 colours and can be laid either vertically or horizontally:

SLAT TED CLADDING COMPONENTS
- Please ensure you are familiar with all the cladding components prior to starting.
PRE-INSTALLATION NOTES
SPACING BOARDS & JOISTS
- Due to the natural expansion and contraction of the composite material with changes in ambient temperature and humidity cladding boards should be installed with an expansion gap between adjoining boards. Refer to the table on page 8 for distances.
- As an example; If installing whole-length cladding boards (3600mm long), and the air temperature at the time of installation is 21°C – the expansion gap should be 4.4mm between adjoining boards – as noted in the expansion gap table.
- Plastic or timber joists should be installed with a 20mm gap between ends.
- A minimum 15mm gap should be provided between the lowest cladding board edge and the ground.
- A clear cavity between the rear face of the cladding and the outer wall/ surface of the structure being clad should be provided of no less than 25mm to allow sufficient airflow.
- Joists should be no more than 500mm from centre to centre.
- Extra care is required to provide sufficient joisting around windows, fascia’s, soffits, guttering, ventilation points and corners of walls. These locations should be planned and coordinated with the Cladding system to ensure alignment with the composite fascias and trims. This will allow the fixing of the cladding & end trims back to the joists.
- A double joist arrangement will be required for mid-panel joints and at corners to allow the joint trims to be seated and fixed to both joists. Consider expansion and contraction as shown.
- Note that netting or foam can be used behind boards to prevent insect nesting.
JOIST SPECIFICATION
- Cladding can be fixed to solid plastic, pressure-treated softwood timber or Aluminium joists depending on design requirements. Both solid plastic joists and aluminium joists can be purchased from us.
- Joists should be fixed into position at 500mm centres using suitable A4 stainless steel countersunk wood/ masonry screws or good quality exterior screws. All joists need to be fixed in a minimum of 3 places.
- All joists need to be a minimum 19mm thick, flat and levelled against the wall. Use shims as required.
- Joists used at external corners should be at least 50mm wide to accommodate the Corner / End Trim and provide space for the screws to fix.
- Prior to installation, a building professional should be consulted regarding vapour barriers and insulation for your project. Where a vapour barrier is to be used, it should be a breathable type and must be positioned behind the joists to allow the cladding a minimum 25mm airflow. It is essential that a barrier/ coating is installed to prevent water penetration.
INSTALLATION METHODS – VERTICAL
Installing the supports
- Joist should be 50mm wide x30mm high and should be fully supported once installed.
- Remember to install your joist at a 90-degree angle to the way that you want your wall cladding boards to run.
- Screws should be 5-6mm in diameter and at least 60mm long.
Securing the boards
- Secure the boards using a screw at least 20mm in length, ensuring that the board is fastened securely on each joist that it touches.
Finishing the edging
- There are a range of trims available in all colours to compliment your cladding boards and these can be secured to your installation by screwing through the trim into the joist below every 300mm.
- Do not screw through wall cladding boards.
INSTALLATION METHODS – HORIZONTAL
Installing the supports
-
Joist should be 50mm wide x30mm high and should be fully supported once installed.
-
Remember to install your joist at a 90-degree angle to the way that you want your wall cladding boards to run.
-
Screws should be 5-6mm in diameter and at least 60mm long.
Fixing the starter profile
- Attach a starter strip to the bottom of each post. this will give the first cladding board something to sit on.
Securing the boards
- Secure the boards using a screw at least 20mm in length, ensuring that the board is fastened securely on each joist that it touches.
Finishing the edging
- There are a range of trims available in all colours to compliment your cladding boards and these can be secured to your installation by screwing through the trim into the joist below every 300mm.
- Do not screw through wall cladding boards.
CLEANING AND CARE
- Our Slatted Cladding boards will require periodic maintenance to remove the build-up of dirt and debris. We recommend the cladding is cleaned once or twice a year using either:
- A high-pressure cleaner (Jet wash) with a fan-shaped beam at a distance of at least 20cm in a lengthwise direction, or;
- Scrubbing brush with an all-purpose cleaner and water
- Burn marks, from BBQs or similar can also be removed using a coarse piece of sandpaper (80gsm or similar), by rubbing the cladding lengthways gently.
EXPANSION GAP TABLE
- Please refer to the table below when installing the cladding boards to determine the gap (mm) between boards and adjacent structures.
- Please note this table covers expansion and contraction values for the UK, Europe
