Capped composite

What is capped composite decking, and why it matters in Perth

Capped composite decking is a wood-fibre and plastic board with a protective polymer shell bonded over the core. The cap is what separates a board that still looks like the sample in ten summers from one that has faded to grey and stained where the barbecue sits. NewTechWood caps every surface of the board including the groove. WoodEvo HOME is HDPE-capped. Millboard goes a different way entirely: no wood in the board at all, a mineral and resin body moulded from real oak so the grain never repeats.

Perth is the climate these boards were built for. The UV is relentless from October to March, the coastal strip carries salt air, and an alfresco that faces west takes the full afternoon sun. A capped or mineral board on the right frame does not need oiling, sanding or staining, which is the whole reason a builder specifies it over Merbau on a deck the client will never maintain.

The three brands we distribute

Which composite decking board for which deck

NewTechWood composite decking

The volume brand and the widest range. Six decking ranges: Avenue as the budget-friendly board, Soho with a 25mm profile on a 450mm span, Terrace as the solid composite for residential and commercial, Coastal at 210mm wide with a deep weathered texture, Marina for waterfront and salt-air exposure, and a Commercial range. Every board is 95% recycled and fully capped, including the groove, with a 25-year limited residential warranty and 10 years on commercial work. Colours run from Antique and Blackbutt through Teak, Ipe, Walnut, Silver Grey, Beech, Aged Wood, Canadian Cedar and Ebony to Sea Salt.

Choose it when: the client wants a timber look at a sensible number, or the deck is big enough that board width and range depth matter.

NewTechWood's decking ranges

WoodEvo composite and PVC decking

The brand with the published numbers. HOME range boards are HDPE-capped composite at 138 x 23 x 5400mm, rated R11 for slip to AS 4586:2013, BAL29, 450mm residential joist centres, 25-year residential warranty, in nine colours. The lighter six carry NatureCool technology, which WoodEvo says keeps the surface 10 to 20 degrees cooler than a standard board. The ADVANCED range is PVC decking with a 30-year warranty, an R13 slip rating, and CodeMark certification, in Antique Silver, Blackbutt, Oak, Sandstone, Smoked Ash and Victorian Maple.

Choose it when: the lot is BAL-rated, the deck is around a pool, or the alfresco faces the afternoon sun and the client walks barefoot.

WoodEvo's decking ranges

Millboard decking

The premium board, and not a composite in the usual sense: wood-free, 38% recycled content including limestone diverted from landfill, bonded in polymer resin and hand-moulded from selected oak boards so no two are alike. Four collections: Enhanced Grain for the smooth timber look, Weathered Oak moulded from century-old boards, Lasta-Grip for wet and high-traffic areas, and Modello in Linear and Contour. Fixed with Millboard's Durafix lost-head screw, on Millboard's own DuoSpan or Plas-Pro subframe where the job calls for it. Designed and crafted in Britain, imported through Millboard's exclusive Australian distributor and supplied through us in Perth.

Choose it when: the client has seen it and nothing else will do, or the deck is a commercial or poolside surface where the slip rating is the spec.

Millboard's collections

Sun, heat and pools

Colour, heat and pool surrounds

Two questions decide more decks in Perth than the brand does. Which way does it face, and is there a pool.

Heat. Every deck gets hot in January and dark boards get hotter. If the alfresco faces north or west and the client walks on it barefoot, spec a lighter tone, and on WoodEvo HOME pick one of the NatureCool colours, Basalt, Hampton, Nordic, Tallowwood, Snow White or Vic Ash, which the manufacturer rates 10 to 20 degrees cooler than a standard board. Shade over the afternoon side does more than any board.

Pool surrounds. The board around a pool needs a slip rating the certifier will accept and a tolerance for chlorine, salt and constant wet. WoodEvo publishes R11 on HOME and R13 on ADVANCED. Millboard's Lasta-Grip is built for exactly this, and Enhanced Grain is sold for poolside use. NewTechWood's Marina range is designed for waterfront and salt-air exposure. Tell us it is a pool deck and the board, the fascia and the edge detail get specified together.

Joists, centres and what it sits on

The subframe decides the deck

Composite boards span less than hardwood, so the frame is set out to the board, never the other way round. WoodEvo HOME is rated for 450mm residential centres. NewTechWood specifies its Soho profile at a 450mm span and publishes centres per range for residential and commercial loads. Lay boards on the diagonal and the centres close up again. Get the frame wrong and no warranty on the board will save it.

What the deck sits on decides the frame:

  • On sand or soil: treated pine joists and bearers on stumps or posts, from the same timber range as the rest of the build.
  • On a slab or pavers: never flat on the concrete. Low-profile joists, composite bearers, or adjustable pedestals so the boards drain and breathe underneath.
  • Near the coast or a pool: steel or aluminium framing, or Millboard's DuoSpan and Plas-Pro subframe, where timber would move or rot in the wet.

Composite also moves with heat, more than timber does along the board. The end gaps, the side gaps and the breaker board on a long run are in every manufacturer's installation guide for a reason, and Perth in February is the reason.

What to order with the boards

A deck order is never just the boards

The Trex shops in Perth sell all of this as separate SKUs and leave you to work out which clip fits which frame. We put it on the one list with the boards:

  • Boards for the deck area, with the waste allowance for the board length and the laying pattern
  • Joists and bearers, or the pedestal or composite subframe the base calls for
  • Starter clips for the first board, and the hidden-fix clips the brand specifies
  • Screws matched to the frame: timber-frame or metal-frame, stainless where it is near the water
  • Fascia or edge boards for the cut ends and the step risers
  • End caps and trims where the profile needs them
  • A breaker board for runs longer than the board

Measure the deck, tell us the board, the base and the pattern, and the whole list comes back as one price. Nothing turns up missing on the day, and nobody drives to a showroom on a Saturday for a bag of clips.

Timber decking Perth

When timber decking is the right call

Composite is not always the answer, and you will hear that from us before you spend. A shaded deck the client is happy to oil, a heritage frontage, a job where the budget stops at the boards: Merbau, Spotted Gum or Jarrah still make sense. Timber decking boards, joists and bearers come through the same account as the composite, sourced through the merchants we buy from, so a timber deck and a composite deck on the same site are still one order.

How it works

How to order composite decking for a build

Three steps, one point of contact from the first email to the truck.

  1. 01

    Send the area and the board

    Square metres of deck, the brand and colour you are pricing, what it sits on (frame on sand, a slab, pavers) and whether it runs around a pool. If you are still choosing, tell us the look and the sun exposure and we suggest the board.

  2. 02

    One price, boards to fascia

    Boards, joists and bearers, starter clips, hidden-fix clips, screws matched to the frame, fascia and end trims, priced as one order by one person. No board quote to reconcile against a fixings quote.

  3. 03

    Delivered to site, to programme

    Delivered across Perth, Western Australia to suit your programme. Need it installed? We link you in with install teams we work with.

We supply across Perth, Western Australia, delivered to site, with a sister operation in Queensland. Residential and commercial builders are most of the order book. Homeowners and self-builders order the same boards with the same guide, and if you would rather not lay it yourself, we link you in with install teams we work with.

Straight answers

Composite decking in Perth, the questions we get asked

If yours is not here, send it through and you will get an answer from the person who prices the orders.

Where is the best place to buy composite decking in Perth?

A supplier who carries more than one brand, will tell you which one suits your deck, and puts the joists, clips and fascia on the same order as the boards. Integrity Building Materials supplies NewTechWood, Millboard and WoodEvo composite decking across Perth, delivered to site, supply only. Send the area and the board and it comes back as one price.

What are the downsides of composite decking?

Three honest ones. Composite boards expand and contract with heat, so the joist centres, end gaps and clip system in the installation guide are not optional. Dark colours run hot in full sun, so pick a lighter tone for a north-facing alfresco. And the bushfire rating is per product, not per brand: WoodEvo and NewTechWood both state BAL29 for decking, but NewTechWood's cladding carries no BAL rating, so ask for the report before anything goes on a rated lot.

Does composite decking get hot in a Perth summer?

Every deck surface does, and darker boards more than lighter ones. WoodEvo's HOME range uses NatureCool technology on its lighter colours, which the manufacturer says keeps the surface 10 to 20 degrees cooler than standard boards. On any brand, a lighter tone and some shade over the afternoon side of the deck make the difference between bare feet and thongs.

Is composite decking slippery, and can it go around a pool?

It depends on the board. WoodEvo HOME publishes an R11 slip rating to AS 4586:2013 and the ADVANCED range R13. Millboard's Lasta-Grip collection is built for wet, high-traffic areas and its Enhanced Grain is sold for poolside use. NewTechWood's Marina range is designed for waterfront and salt-air exposure. Tell us it is a pool deck and we spec the board and the edge detail to suit.

Are composite decking boards fire resistant or BAL rated?

Only where the manufacturer has tested them. WoodEvo decking carries a BAL29 rating and NewTechWood states BAL 29 for its decking in bushfire-prone areas. Millboard is wood-free but you should ask for its fire data for the application. On a bushfire-prone lot, tell us the BAL level and we price a board that has the report to match.

What joist spacing does composite decking need?

Closer than timber. WoodEvo HOME boards are rated for 450mm residential centres, and NewTechWood's Soho profile is specified at a 450mm span. Every brand publishes its own centres for residential and commercial loads, and for boards laid on the diagonal, so the frame is set out to the board you have chosen, not the other way round. Send us the board and we supply the joists to suit.

Can I lay composite decking over concrete or pavers?

Yes, on a subframe. Composite boards are never laid flat on a slab. They go on joists, composite or aluminium bearers, or adjustable pedestals that give the boards the ventilation and the drainage the manufacturer requires. Millboard sells its own DuoSpan and Plas-Pro subframe systems. Tell us what the deck sits on and the frame goes on the order with the boards.

How long does composite decking last?

The manufacturers back it with the warranty. NewTechWood carries a 25-year limited residential warranty and a 10-year commercial one. WoodEvo HOME is 25 years residential and the ADVANCED PVC range 30 years. A capped or mineral board that is laid to the guide, on the right centres, with the right gaps, is a deck you stop thinking about.

How much does composite decking cost in Perth?

It comes down to the brand, the board width and profile, the frame it sits on, how many cut-ends and steps there are, and the size of the deck. We do not publish a per-board or per-metre rate, because a deck price that leaves out the joists and clips is not a deck price. Send the area and the board and you get one number for the lot.

Do you install decking, or can I lay it myself?

Supply only. We price and deliver the boards and everything under them. Builders and carpenters lay most of it. Self-builders order the same boards and get the same installation guide, and if you would rather not lay it yourself, we link you in with install teams we work with.

Got a deck to price?

Send the area and the board, or call 0407 380 788. Boards, joists, clips and fascia come back as one price from one person.
