The Unique Lastane® layer resists scratches and stains and is designed to withstand demanding outdoor environments.

Millboard is wood-free and non-porous, which means high resistance to algae growth and excellent anti-slip properties.

The dual-tone Lastane® surface is hand tinted using pigments designed to resist fading and sun damage.

Our unique ‘cellular’ internal structure reduces weight while maintaining strength.

Millboard is solid, not hollow, meaning it’s strong and won’t warp, rot like wood, or harbour insects and pests.

The structural core is a blend of natural minerals bonded in a polymer resin with long fibre reinforcement for added strength and durability.

How is Millboard Made?

Millboard composite decking is hand-made in the United Kingdom & styled from real oak timbers, creating an incredible realistic look that captures the natural beauty of wood. But unlike traditional timber – which needs regular on-going maintenance like oiling & sanding to try and stave off rotting, mould, stains, warping, cupping, fading, splinters & a host of other undesirable effects.

Millboard is totally different! This is because unlike traditional timber, or even conventional composite decking WPC (which typically contain half timber fibre / flours / rice husks & half plastic) – Millboard contains no timber, nor any plastic. Millboard composite decking is made from a revolutionary Polyurethane resin, reinforced with mineral fibres plus a unique Lastane® coating. So what is Polyurethane then? It’s a type of elastomer, which is a polymer about half way between a plastic and a rubber. It maintains the rigidity & longevity of plastic, with the suppleness of rubber. This means Millboard feels much more natural under foot, while still offering incredible durability.

Millboard composite decking is hand-made in the United Kingdom and styled from real oak timbers, creating an incredible realistic look that captures the natural beauty of wood. But unlike traditional timber – which needs regular on-going maintenance like oiling and sanding to try and stave off rotting, mould, stains, warping, cupping, fading, splinters and a host of other undesirable effects – Millboard is totally different! This is because unlike traditional timber, or even conventional composite decking WPC (which typically contain half timber fibre / flours / rice husks & half plastic) – Millboard contains no timber, nor any plastic.

Millboard decking is extremely versatile and can be used to create not only beautiful decks, but also can be used for Cladding, both vertically and horizontally, for ceiling lining, steps, bridges, pontoons, balconies, planter boxes, gardens and so much more!

Why not get inspired by looking through recent Millboard projects in our Gallery?

Of course! – If you would like a sample please contact us and we can send some samples out to you. Please let us know what colour and texture (Weathered Oak or Enhanced Grain) you are thinking about, and any other information about your upcoming project such as sqm2, residential or commerical etc. We can help with your choice and offer tips on getting the most out of Millboard. If you are an Architect, Specifier or a Builder we also have Architect’s Sample Packs available which showcase the full Millboard composite decking range.

Millboard is chemically inert and does not contain any timber so the boards will not absorb moisture, swell, warp or rot in the way that timber does. As such Millboard does not require any ventilation or minimum clearance from the ground making it perfect solution for ultra-low decks.

Millboard decking boards can be cut in much the same way as regular timber. We recommend a carbon tipped multipurpose saw. Plastic composite decking tends to blunt saw blades very quickly and be difficult to screw and work with – but with Millboard this isn’t a problem! Don’t forget that we have Touch Up Paint available in 500ml tins for colour matching exposed cut ends.

Fixing Millboard couldn’t be simpler! There are no fiddly and expensive clipping systems, no pre-drilling nor any countersinking required. Millboard decking is simply top fixed like real timber – But with an incredible “lost-head” hidden fixing. The Lastane® layer self heals over the screws to leave a near indistinguishable mark for a clean finish! After extensive testing we recommend and supply Durafix Stainless Steel screws for the best results.
See videos of the screws disappearing.

With Millboard’s wide range of colours, you can choose what is best for you. As with all products, the darker colours will feel hotter underfoot in sunny exposed locations. If this is an issue, opt for lighter colours for such locations.

Yes! Millboards tested a BS79.76 slip resistance in both textures, and lead the industry with their high scoring anti-slip ratings – even in wet conditions! This is one of the reasons Millboard is so popular with councils as it meets and exceeds the requested anti-slip requirements for public use.

The Lastane® finish is highly resistant to scratches and food and drink stains.

Yes, Millboard is fire rated to Australian Standard BAL19

In instances where there is burning wood or coal they will need to sit the fire bowl / brazier onto a porcelain or cement tile / slab. The slabbed area needs to extend about 1m outside the fire bowl / brazier. Any embers or burning material needs to be removed immediately to prevent any damage or lasting marks to the Millboard surface. Patio heaters or infrared heaters are not known to affect the boards.

Because Millboard is made of non-porous composite, it resists mossy build-up and stains, so needs very little maintenance. To remove spills and marks – or just generally give your deck a clean – simply use a mild detergent, garden hose and a brush. Steer clear of solvents, chemicals or abrasive cleaners that could damage your Millboard. Similarly, Pressure Washing is usually not necessary and may damage the boards at high pressure.
