Best composite decking in Australia

The best board depends on your site: sun exposure, bushfire zone (BAL), budget and frame. We compare what manufacturers publish (profile, sizes, warranty, BAL information where stated). We have not lab-tested these products.

How do you pick a composite decking brand in Australia?

Start with the constraints that rule options out, then compare what is left. We don’t give ratings, because we haven’t tested any board. What we can do is show who publishes what.

1. Bushfire rating

BrandRated boardRating stated
ModWoodFlame ShieldBAL-40 (AS 1530.8.1-2007); ModWood says only Flame Shield may be used in BAL-rated zones
EkodeckFlame Fighter; Designer and Summit per a site bannerBAL-29
FuturewoodCleverDeck Co-ExBAL-29; CleverDeck Original BAL-low and sometimes BAL-12.5 or 19
NewTechWoodCoastalBAL-29 on its technical sheet
Millboardnone found

2. Heat

All the makers that answer say dark colours run hotter. ModWood says a board in full sun runs 20 to 25 degrees above the air, Futurewood says dark boards can run 20 or more above, and Ekodeck says Classic is marginally hotter than timber. Pick a lighter colour; see does composite decking get hot.

3. Warranty

BrandResidentialCommercial
ModWood Xtreme Guard25 years10 years
NewTechWood25 years, plus 25 year stain warranty10 years
Ekodeck Classicup to 15 yearsup to 15 years
Futurewood10 years7 years

Check the exclusions. NewTechWood doesn’t cover use of a high-pressure cleaner. Ekodeck limits mould and mildew defects to two years.

4. Coast and pools

ModWood says its boards are unaffected by salt air. Futurewood says Xtreme suits coastal areas and pool surrounds and tells you to wash corrosive pool chemicals off immediately. NewTechWood says chlorinated pool water won’t harm its boards but undiluted chlorine and pool salt shouldn’t be spilled on them.

5. Maintenance and frame

ModWood and NewTechWood both advise against high-pressure cleaners, while Ekodeck allows up to 2000 psi with a fan nozzle. Joist spacing is 450 mm for ModWood, Ekodeck Classic, Futurewood and Avenue, and 400 mm for Coastal. See the boards table.

What we can’t tell you

Prices. None of these makers publishes a dated AUD price, so the cheapest option is whoever quotes lowest for your deck. Enter the quotes in the cost calculator.

Questions

What is the best composite decking in Australia?

It depends on your site, and we don't pick a winner. If your block is bushfire-prone, only boards with a certificate for your BAL are options. On the coast, check salt and pool statements. If heat matters, colour matters more than brand.

What is the best composite decking for the coast?

ModWood says its boards are unaffected by salt air. Futurewood says CleverDeck Xtreme is highly suitable for coastal areas and around pools. Neither is a test report, so ask for the maker's documents and check the warranty exclusions.
