Frequently Asked Questions

What is Millboard Decking?

Millboard is the only decking hand-moulded from natural timbers, making it the most realstic composite decking available. Unlike timber, Millboard decking is virtually maintenance free, is highly slip and stain resistant and won’t rot from fungal decay or warp in the way that timber can.

Millboard decking uses a unique material, unrivalled across the globe. Made from polyurethane and resins, reinforced with fibreglass for additional strength & stability. The Lastane® surface is pliable and provides high slip-resistance compared to timber, even in wet conditions.

ToughThe unique Lastane layer resists scratches and stains and is designed to withstand more demanding outdoor environments than timber can.

EnduringThe dual-tone Lastane surface is hand tinted using pigments designed to replicate the look of natural timber

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

LighterMillboard's unique closed 'cellular' internal structure reduces weight while maintaining strength.

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

DurableMillboard decking is solid, not hollow. This makes it strong and means it won't warp, rot or harbour insects and pests like timber would.

Can I get a Sample?
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.
Can I see Millboard installed or are there displays?
Yes - select stores have displays of Millboard decking, and Millboard has been used in several prominent major public works. Millboard has even been used for an Alfresco Cinema! If you would like to see Millboard decking "in the wild", please contact us with your general location (state/town) and we can advise you of the nearest place to go and see Millboard.
Can you recommend an installer?
If you contact us with we should be able to help! We can recommend installers in your area that have a high quality of workmanship and professionalism so that you get the best out of your Millboard project.
Does Millboard come with a Warranty?
Yes - An industry leading 25Y Residential limited warranty! Millboard decking gives you peace of mind against rotting such as fungal and mildew decay, splitting and twsiting. Millboard is handcrafted in the U.K., for full warranty details please see the warranty page here
Why is Millboard virtually maintenance free?
Millboards is manufactured with non-porous material, meaning that it doesn't absorb moisture. This makes it highly stain resistant - Do not use any kind of solvent, chemicals, abrasive cleaners, sanding, sealing wax or oil, or even any household cleaners! A simple brush down & rinse with some soapy water is all that's needed to clean Millboards. There is no need for pressure wash as there are no pours for dirt to become ingrained in!
If that wasn't low maintenance enough, unlike traditional timber or even common Wood/Plastic composites, Millboard decking also doesn't contain any timber, flour or husk fibres (which all have sugars in them), so Millboard will not host algae or mould growth.
Is Millboard decking anti-slip?
Yes! Millboards in the BS79.76 slip resistance tests both textures 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.
Does Millboard mark?
The Lastane(R) finish is highly resistant to scratches and food & drink stains.
Can Millboard be used in other applications?
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 & so much more!

How do you cut Millboard, is it the same as wood?
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 screw & to 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.
What joist spacing do you recommend?
Joist spacing of 400mm centres is recommended for normal residential use. On commercial decks, bridges, balconies, moorings, doorways, steps and public areas - use 300mm spacing. If you need to cut Millboard down along the length, then reduce the joist centres accordingly.
How do you fix Millboard? What fixings should you use?
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(R) layer self heals over the screws to leave an near indistinguishable mark for a clean finish! After extensive testing we recommend and supply Durafix Stainless Steel screws for the best results.

Why is there a slight variance in the boards?
There will always be a slight variance in the board’s dimensions due to the fact that we mould from natural oak, and due to the pressure of the moulding process. Despite this, we calibrate the boards to maintain as consistent a profile as possible. The manufacturing tolerances are: Width: ± 3mm. Length: ± 5mm. Thickness: ± 2mm. The dimensions of the Weathered Oak style may vary more between moulds due to the fact that they are moulded from timeworn oak with minimal changes to the dimensions. When working with the boards, packers may be required to create a flush finish between two boards. Dimensional variation is also possible with our Our Envello® cladding boards and therefore the same manufacturing tolerances are applicable (Width: ± 3mm. Length: ± 5mm. Thickness: ± 2mm). When using our Shadow Line product, in order to achieve straight and consistent 6mm gapping between boards, it may be necessary to use our Millboard Multi-Spacers during the installation process. For further details please refer to our Envello® Cladding Installation and User Guidance in the Help & Advice section of our website.

Buyers Awareness

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.

To recreate the aesthetic of natural colour variation, Millboard intentionally adds secondary toning colours. There may be variance within the same board or from board to board in colour tone. This means that samples cut from boards may vary from the general colour of the boarding.

Whilst every care is taken to ensure consistency some colour variation from batch to batch may occur. To avoid this, we recommend that you order all you need in one delivery. If you do have different batches it is best to mix the batches to blend the colours.

As with all things constantly exposed to ultra violet light and all weathers, colours will tone slightly in time, this is normal for decking. On delivery if you find the colour unacceptable or believe them to be defective in any way, do not install the boards.
