WPC cladding is a wood-plastic composite board made from wood fibre and polymer, used to give walls a timber look without the oiling and repainting. Installed WPC cladding in Sydney commonly runs about $150–$350 per m² (indicative — get itemised quotes), depending on the range, the wall and the access. This guide suits owners comparing composite boards with timber, fibre cement and metal. It covers types, costs, installation rules, fences, black finishes, fire and bushfire checks, and the mistakes that cause warping and staining.
Key points
- WPC cladding trades the upkeep of timber for higher upfront cost and more thermal movement, so gaps and clips matter.
- Dark colours look sharp but run hotter and move more, so follow the maker’s expansion and fixing rules.
- Check bushfire rating, fire test reports and the board’s warranty terms before you order any composite cladding.
- Aluminium composite panel is a different product from WPC, and its core and compliance need checking.
What is wpc cladding?
WPC cladding is made by blending wood fibre with plastic and shaping it into boards, panels or slats. A capped version adds a protective outer layer for colour and stain resistance.
It’s fixed to battens with concealed clips, so the face stays clean and the boards can move with temperature. It’s used on façades, feature walls, fences and screens.
- Core: wood fibre and polymer, either solid or hollow, depending on the profile.
- Surface: embossed grain, smooth or brushed finishes, with or without a protective cap layer.
- Fixing: concealed clips and rails, with trims at ends and corners.
- Movement: expands and contracts with temperature, so it needs gaps that the maker specifies.
- Finish: usually factory coloured, and painting may void the warranty, so check first.
- Warranty: terms differ by brand, so read them for fade, stain and structural cover.
| Term | What it means | Why it matters |
|---|---|---|
| WPC | Wood-plastic composite made from wood fibre and polymer | Gives a timber look with less upkeep than real wood |
| Composite timber cladding | Another name for WPC boards used on walls | Same product family, so compare specs, not names |
| Aluminium composite panel | Metal skins bonded over a core, not a wood composite | Different material, with its own fire and compliance checks |
| PVC cladding | Plastic boards without wood fibre | Lighter and waterproof, but with a different feel and rating |
| Capped board | WPC with a protective outer layer | Better stain and fade resistance |

- Wall prep: uneven or damp walls need straightening and repairs before battens go on.
- Cavity and flashings: good detailing adds labour but protects the frame behind.
- Colour and brand: darker or premium ranges cost more per board.
- Access: two-storey façades need scaffolding or platforms.
- Trims and clips: end caps, corners and starter rails add up on complex walls.
- Waste: allow extra for cuts, windows and patterns.
Pros and cons of wpc cladding
Pros
- Timber look with no oiling, staining or regular repainting.
- Resists rot and termites better than most untreated timber.
- Comes in factory colours that stay consistent across a wall.
- Clips hide fixings, so the face stays clean.
- Works for walls, fences, screens and soffits.
- Washes clean with mild soap and water.
Cons
- Costs more than basic painted boards at purchase.
- Expands and contracts with temperature, so detailing matters.
- Dark colours get hot in Sydney summer sun.
- Can scratch, and deep scratches are hard to hide.
- Fire performance varies, so bushfire areas need checks.
- Painting may void the warranty.
How to choose wpc cladding
- Check your bushfire rating first, then ask for fire test reports that match it.
- Choose capped boards for sun-exposed walls, because the cap layer resists fade and stains.
- Pick the colour carefully, since darker boards run hotter and show movement gaps more.
- Compare clip systems, because proper clips and rails matter more than the board face.
- Read the warranty for fade, stain, structural and installation conditions.
- Get a sample and leave it in the sun and the shade to see how it behaves.
WPC cladding installation and maintenance essentials
- Test pre-1990 walls for asbestos before drilling or fixing, and stop work if the result is positive.
- Fix battens to a flat, dry frame to create a ventilated cavity behind the boards.
- Flash windows, doors and penetrations before the first board goes on, so water drains out.
- Leave the expansion gaps the manufacturer states at ends and edges, and use the maker’s clips only.
- Keep boards off the ground and garden beds so soil and water don’t wick up.
- Wash twice a year with mild soapy water and a soft brush, avoiding solvents and pressure washers.
WPC wall cladding and wall panels exterior
- Use a WPC panel on feature walls where you want a bold look without a heavy timber frame.
- Choose WPC exterior wall cladding rated for the sun, and avoid interior boards outdoors.
- Treat WPC external cladding and composite external cladding as one family, and compare data sheets, not product names.
- Specify an exterior WPC wall panel or WPC outdoor wall cladding only with the maker’s clip and rail system.
- Match the panel to the wall: brick, render and framed walls need different fixing rails.
- Plan outdoor wall panelling around lights and meters, and use licensed trades for electrical moves.
WPC cladding for fences and screens
- Use composite timber fencing where you want low upkeep and consistent colour along a long run.
- Choose outdoor fence cladding with a solid or co-extruded profile that resists impact.
- Fix to a sound frame, because composite boards are heavy and sag on weak rails.
- Allow for wind loads on tall solid screens by following the engineer’s or maker’s design.
- Check boundary and council rules for height and neighbour consent.
- Book a licensed fencing contractor for the fence build, as it is a separate trade from cladding.
Black cladding exterior and slatted cladding looks
- Use black cladding exterior sparingly in full-sun spots, because dark boards run hot and move more.
- Choose slatted cladding over a dark backing so the gaps read as shadow lines.
- Keep slat cladding spacing even, and use a spacer jig to avoid drift on long runs.
- Pair dark boards with light trims, from ranges by Dulux or Taubmans, for contrast.
- Test the sample at midday to see how hot and glossy the colour looks.
- Ask about colour-fade cover in the warranty, since dark colours show wear sooner.

Fire and compliance checks for composite cladding
- Find your bushfire attack level through your council or a certifier before you shortlist any composite board.
- Ask for fire test reports that match that rating, and keep a copy with your building records.
- Confirm the core of any aluminium composite panel, because some cores burn and have been restricted on many buildings.
- Check strata and council rules before you change the look of a façade or add cladding to a shared wall.
- Keep the installation instructions and photos of the cavity and flashings, which support any later warranty claim.
- Use licensed trades for electrical moves, scaffolding and any structural changes behind the boards.
Common mistakes to avoid with composite boards
- Fixing boards tight against fixed objects, so expansion in summer pushes them out of line.
- Using the wrong clips or screws, which voids warranties and lets boards slip.
- Skipping the cavity, so moisture sits behind the boards and rots the frame.
- Choosing a dark colour for a west wall without testing how hot and glossy it looks.
- Cleaning with solvents or a pressure washer, which scratches the surface and dulls the colour.
- Buying on price alone without matching board type, cap layer, clips and trims across quotes.
WPC cladding FAQs
How much is Ekodeck per square metre?
Ekodeck is a composite decking brand, and pricing varies by range, colour and supplier. Composite decking is commonly around $120–$250 per m² for boards alone (indicative — get itemised quotes). Ask for the current price list, and compare it with installed pricing, because framing and labour change the total.
Is WPC cladding suitable for bushfire areas?
It depends on the product and your bushfire attack level. Some composites aren’t suitable in higher ratings, and fire performance varies by brand. Ask the supplier for test reports that match your rating, and confirm with your certifier before you order any composite cladding.
How long does WPC cladding last?
Lifespan depends on the product, the colour, the sun exposure and the installation. Quality capped boards fitted with proper clips and gaps can last many years with only washing. Read the warranty carefully for fade, stain and structural cover, and follow the maintenance rules it states.
Does WPC cladding get hot in the sun?
Yes, especially in dark colours. Boards expand when hot, so they need the gaps the manufacturer specifies. Choose lighter colours for west-facing walls, test a sample at midday, and avoid fixing boards tight against fixed objects where they can’t move.
Can you paint WPC cladding?
Often not. Many manufacturers advise against painting, and painting can void the warranty. If you need a colour change, ask the maker which coatings, if any, they approve, and follow the label. A licensed painter can advise on suitable products.
Is aluminium composite panel the same as WPC?
No. Aluminium composite panel is a metal-faced sheet with a core, while WPC is a wood-fibre and polymer board. They suit different looks and have different fire and compliance checks. Confirm the core type and approvals with your certifier before choosing either.
