Millboard Decking

​

If you’re after a high-end deck that looks just like real timber but won’t split, warp, or fade, Millboard composite decking is one of the best options on the market — and we install it across Sydney.

At ACM Decks, we’ve worked with Millboard on everything from sleek rooftop terraces to large entertaining decks with built-in seating and stairs. Whether you’re in the Inner West, Northern Beaches, or North Shore, we can build something that’s beautiful, low-maintenance, and built to last.

Why Millboard?

Millboard is different from most composite decking brands. It’s made with a unique polyurethane resin core and finished with a hand-moulded top layer that’s taken from real timber grain — so you get the natural look without the downsides of wood.

What sets it apart?

• Ultra-realistic timber finish

• Won’t rot, warp, or crack

• Slip-resistant – even when wet

• Low maintenance – no sanding, sealing, or staining

• Resistant to algae, fading, and moisture

• Hidden fixing system for a clean look

• 25-year residential warranty

It’s a great choice for premium outdoor spaces, especially around pools, garden edges, or where timber would normally struggle with weather or wear.

FAQs About Millboard

Is Millboard slippery when wet?
Not at all. It’s one of the most slip-resistant decking materials we’ve worked with — ideal around pools, outdoor showers, or shaded areas.

How is Millboard installed?
Millboard uses a unique Durafix® hidden fixing system, so there are no visible screws. The boards are installed on treated timber or composite framing, depending on the setup.

Does Millboard fade over time?
It’s UV-stable and fade-resistant, even in Sydney’s summer sun. What you see when it’s installed is what you’ll get for years.

Is it more expensive than timber or other composites?
Yes, Millboard sits at the premium end of the market — but its durability, low maintenance, and visual finish often make it the last deck you’ll ever need to build.
