What is Composite Decking?

Composite decking has become the newest buzzword in outdoor living, but what does it *actually* mean?
Composite boards consist of a core and a cap. This makes composite seem like a simple product, when the make-up of your board is anything but simple.
The core of composite is made up of two primary ingredients: wood (e.g. sawdust, wood chips, wood fibre) and plastic. However, unlike timber which requires trees to be felled, composite decking sources wood from recycled materials, making your new deck an environmentally-friendly addition to your Sydney home.
And to protect the core, each board is capped with a bonded polymer. This adds protection against weathering, fading, scratching, bleaching, staining and mould.
Put simply, composite decking is the fastest growing timber-alternative on the Australian market.
Long gone are the days when timber-alternative products meant sacrificing aesthetic beauty. In fact, you’ve probably enjoyed time in the great outdoors on a composite deck that looked indistinguishable from hardwood timber.
So while it’s easy to say composite decking is “not wood”, that would be selling things short. Composite decking is the fastest growing alternative to timber decking on the planet, and with a list of benefits as long as your arm, it’s easy to see why.

What Are the Benefits of Sydney Composite Decking?

At UrbanArch Building we’ve got years of experience working with Sydney homes to turn unused outdoor spaces into functional and exciting decks that become central to the way you live your life.
But we also know you’re not here to hear us talk about ourselves, you’re here to find out what advantages a new composite deck would bring to your day-to-day life.
When it comes to a low-maintenance deck that keeps money in your pocket, it’s tough to go past these benefits:
With the appearance of stunning timber, but the durability advantages only man-made decking can offer, a composite deck is for the Sydney homeowner who values their time outdoors

How is Composite Decking Made?

When you plan on spending your weekends relaxing outside, it helps to know the boards underfoot can handle any guests, outdoor furniture, and elements that Sydney has to offer.
Composite decking is made through what’s known as an ‘co-extrusion’ process.
This combines all of the raw materials needed to create a composite decking board (e.g. sawdust, wood fibres, wood chips, recycled plastic), and melts them into a mixture. This mixture is then shaped into the decking boards you’ll see online and at your local hardware store, making it tough to spot the difference between timber and composite.
But unless you’ve got incredible x-ray vision, what you won’t notice is the additional protective layer, bonded to the substrate to prevent delamination (i.e. layers splitting in your deck). This process might be invisible, but it adds a rock-hard shell to protect against foot traffic, stains and spills, plus protection from the sun’s harmful UV rays which can fade natural timber.
So while composite decking may look like rustic, gorgeous timber, it’s brilliant texture and resilient exterior have been scientifically made to stand up to everything that Sydney can throw at it (and then some).

How Much Does Composite Decking Cost?

Let’s talk dollars and cents.
As an average, the price of a single composite decking board starts at $50 and goes up from there. But your home isn’t average, and neither are we.
That’s why it’s easier to quote a project based on total costs (which includes installation as well as decking boards) which leaves the average cost of a composite deck sitting between $180 to $200 per square metre – this covers decking boards and hidden fasteners.
As with any decking project, you’ll need to factor in a few variables relating to the cost of your finished deck. These typically include:
At UrbanArch Building we set the standard in quality, low-maintenance alternatives to timber that won’t break the bank. Our decks are designed for Sydney’s unique conditions and offer unrivalled lifestyle advantages, so if you’re interested in learning more, call 0413 185 735.

How long does it take to install composite decking?

Composite decking is designed to be durable and easy to install. We’ll need to secure council permission (if necessary) prior to construction, with an estimated 8 to 10 weeks between filing the paperwork to completing your new deck.

Why Should You Pay More for Composite Decking (When Timber Is Cheaper)?

Every savvy Sydney homeowner knows a home improvement project is much more than an upfront price.
If you’re paying a handyman to build a deck out of wood you found washed up on Bondi Beach then you’ll be saving money hand over fist. But when that deck starts splintering and cracking within weeks you’ll face years of expensive repairs and fixes.
The same goes for composite decking.
It’s true that a composite deck for your Sydney property will cost more than the same-sized timber deck, but you’ll make that money back (and then some) as the years go by. This is because composite decking doesn’t need the annual maintenance and attention that hardwood timber requires.
No staining. No oiling. No painting.
Better still, composite boards don’t splinter, warp, rot, or deteriorate in the harsh Australian elements, so you can save hundreds of dollars every year that would have gone towards deck care.
Over the 25 year lifespan of a 30 sq metre composite deck, this can add up to savings of $22,500 to $45,000, depending on the amount of maintenance required.

How to Compare Composite Decking Materials

Composite decking has been a popular choice for outdoor decks and entertainment areas for over 30 years, so naturally there’s a wide range of brands to choose from.
Over time, brands have introduced dynamic innovations, new materials, upgraded manufacturing processes, and modern installation techniques to help deliver a superior deck – but this does make choosing the right composite decking material more of a challenge for you.
The truth is, composite decking is not made equal.
Land on the wrong composite board and you can quickly end up with a deck that’s not worth your investment, and likely to cost plenty in future repair and maintenance costs. To help you choose the best composite board for you, always compare:
Wondering what to look for to choose the best composite product? Here’s a simple step-by-step process to help you sort the average from the extraordinary.

Capped Composite Decking vs. Uncapped Composite Decking

With endless boards advertising themselves as ‘Maintenance-Free’ it’s tough to know who’s telling the truth and who’s peddling false information.
The most important thing to know is that capped decking falls into the ‘Maintenance-Free’ category, because they’re protected with an extra layer that’s bonded to the surface of your decking boards during the manufacturing process.
While early, first generation composite boards were uncapped (meaning they were at risk of fading, mould and mildew), composite decking in 2021 is available capped. At UrbanArch Building we only offer the best decking materials, meaning every composite product we source and install offers advanced premium protection on all four sides, keeping your decking boards safe and secure against outdoor furniture scratches, harmful UV rays, and clumsy family members.
Best of all, the bonding process occurs during manufacturing and under extremely high temperatures. That means no chemicals, no nasty bonding agents, and no adhesives that can end up in your garden.
