Authentic Timber Appearance Without the Drawbacks

What sets Millboard apart from other composite decking options is its remarkable ability to replicate the genuine look and feel of natural wood. Each board is carefully crafted using impressions taken from premium oak timber, resulting in an incredibly realistic wood grain texture that’s virtually indistinguishable from the real thing. However, unlike traditional timber decking, you’ll never have to worry about rotting, warping, or dangerous splinters.

Engineered for British Weather

Designed and manufactured right here in the UK, Millboard decking is specifically engineered to withstand our challenging climate conditions. From heavy rainfall to frost and UV exposure, this premium decking material maintains its appearance and structural integrity year after year, making it an intelligent investment for any outdoor space.

Because Millboard decking is made of non-porous composite, it resists mossy build-up and stains, so needs very little maintenance. To remove spills and marks, simply use a mild detergent and a brush. Steer clear of solvents, chemicals and abrasive cleaners that could damage your Millboard decking. There’s normally no need for pressure washing.

The Lastane® finish is highly resistant to scratches, food-and-drink stains, and everyday wear and tear. Sharp objects such as unprotected table or chair legs, spiked shoes or metal planter bases can leave marks if dragged across the surface, so take care when moving these items around. The risk of marking from strong dyes and stains such as berries and animal droppings will be reduced if removed as soon as possible.

A small amount of granulated white salt can be used to keep your Millboard decking ice-free. Please don’t use rock salt, as this contains clay and grit and can be abrasive. When winter’s over, clean the surface with soapy water and a soft broom.

Timber is the most commonly used sub frame material, and most have a 15 year warranty. However this is only under ideal circumstances and if the cut elements are retreated. In applications where the timber is in contact with the ground or has limited airflow then this will impede on the durability, and in some cases reducing it down to 1/3 or it’s intended lifespan.

At Millboard we recommend to use a wood free alternative to maximise the durability of your sub frame system. We have provided the Plas-Pro system, and 100% recycled plastic non-rot profile. When using this as an alternative to timber bear in mind that the structural spans are not equivalent.

Please refer to the Plas-Pro brochure or Installation Guide for further details. If in doubt then contact a member of our technical team on technical@millboard.co.uk.

Yes. Our warranty gives you peace of mind that we will stand by our word and will hold to the conditions as laid down in the warranty document. We will issue you with either a 25 year Residential Warranty or a 5 year Limited Warranty depending on the installation application of the boards and when it is registered within 90 days of the installation.

All types of Millboard decking has been tested by BBA, certificate 17/5409 for use as Decking Boards and certification and testing has been to this end.
Millboard decking has been tested to BS EN ISO 13501-1:2007+A1:2009 and has a Bfl-S1 reaction to fire classification (fire test for flooring). Millboard decking is not recommended for use as cladding on buildings 18m (6 storeys) or above, and for other cladding use, it should be subject to Building Regulations to check suitability, use and proximity.

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 infra red heaters are not know to affect the Millboard.

No, it is not needed! Durable, through-body coloured and UV stable, Millboard is a low maintenance product that does not require a protective coating. Paints and stains will not properly adhere to the surface.

It is not recommended to use Millboard in structural applications. Millboard decking would need to be fixed to a structural frame, either made of timber or ‘Plas-pro’ recycled plastic.

Yes you can, where the edge is merely aesthetic, such as a balcony edge, if this is your preferred finishing option. However, where the edge is likely to sustain impact, such as a step, we do not recommend using a standard board. Our edging boards have been specifically designed with high impact in mind and as such have a thicker Lastane® surface to withstand the knocks and scrapes associated with step edges and other associated applications.

The majority of our boards are manufactured to the sizes stated on our product pages. However, on occasion some of our board sizes can have a nominal difference and can be manufactured to 30mm or 31mm. The boards that are sometimes this smaller size are still within tolerance.

The ideal companion is our all-weather composite decking is Plas-Pro, a durable, hard-wearing and practical sub-frame material for spaces exposed to damp such as jetties, fishing platforms, pools, roof terraces and boardwalks. The Plas-Pro Millboard sub-frame system is made from 100% recycled plastic, which means it won’t rot, split or crack.

As the boards are a moulded product we use a release agent in the manufacturing process so when the boards are first delivered this release agent is still on the surface. This may result in the boards looking like they have a shiny or waxed surface or have small particles of dirt and water puddling which could cause slip issues. This release agent will come off the surface within 6-8 weeks due to natural weathering. This process can be accelerated by cleaning the boards with warm soapy water and stiff brush after installation.

No, all Millboard decking is surface-sealed in the factory to ensure they arrive in premium condition. In the first few weeks of use, rainwater will sit on the surface in globules, but don’t worry – this is normal and will stop once the temporary surface seal breaks down.

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 foam. Despite this we calibrate the boards to maintain as consistent a profile as possible. The tolerances to allow 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.

CAUTION – In high temperatures or prolonged bright sunlight Millboard decking can become hot. Please exercise caution before walking barefoot on to Millboard decking in circumstances where the decking is in high temperatures and exposed to sunlight. In these circumstances, it may be necessary to use footwear. Special caution should be taken when using Millboard decking in areas where there is heat/UV reflective glass.

Environmental consciousness is at the heart of Millboard’s manufacturing process. Created entirely from recycled materials with zero timber content, choosing Millboard means you’re making an eco-friendly decision without compromising on quality or aesthetics.

Millboard decking can be cut with standard saw blades, although we recommend a carbon-tipped, multi-purpose chop saw. As the formed end of the board is lost when cut, these can be placed in less visual areas against a wall or edging profile. Matching Touch-up Coating for exposed ends is available to buy separately.

As with all flooring, we advise buying all the Millboard decking you need at the same time to help ensure that the colour is as consistent as possible. If you don’t order all your Millboard decking at once, you can blend different batches to create only subtle variation throughout your space.

The advanced engineering behind Millboard creates a decking solution that outperforms traditional materials in every aspect. It won’t fade, stain, or deteriorate like timber, ensuring your outdoor investment continues to add value to your property for decades to come.

One of the most compelling reasons homeowners choose Millboard is the virtually maintenance-free experience it provides. Forget about annual staining, sealing, or treating – Millboard retains its beautiful appearance with minimal upkeep, saving you both time and money over the years.
Simply brush or wipe away fallen leaves and debris to keep it looking pristine.
