Millboard decking is extremely versatile and can be used in practically every outdoor space (subject to building control). Create decks, cladding, balconies, roof gardens, boardwalks, bridges, pontoons, seating, steps, planters and more. Millboard can be used as the decorative face for most outdoor designs, as long as it is fixed to a structural element.
Millboard has been designed to replicate the natural variances of timber and we do not intend for the product to have identical shades. Buying all the Millboard decking you need at the same time should help to ensure that the colour is as consistent and we would always recommend laying out the boards before installation, to create an effective, subtle blend.

Samples are provided as a representation of the product and we would encourage customers to view full boards as part of a deck, in order to fully appreciate the product, prior to purchase.
As with all composite products, the surfaces of the boards tend to be hotter than timber when exposed to direct sunlight. Darker colours particularly will feel hotter and may be uncomfortable to walk on in bare feet. Under direct sunlight and high temperature, footwear may be necessary. Special caution should be taken when using decking in areas by heat/UV reflective glass, or around pools.
The Lastane® finish is resistant to food and drink stains and scratches, and everyday wear and tear. Sharp objects such as unprotected table or chair legs, spiked shoes, animal claws 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. Cover the boards from any surrounding building works or painting that could mark the surface of the boards
Yes. Our Limited Warranty gives you peace of mind and we assure you that we will stand by the provisions, as laid down in the Limited Warranty document. We will issue you with either a Residential 25 year Limited Warranty or a Commercial 5 year Limited Warranty depending on the installation application of the boards and when it is registered within 90 days of the installation.

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 is not recommended for use as cladding or balcony decking on buildings 18m (6 storeys) or above, and for other use, it should be subject to Building Regulations to check suitability, use and proximity.

The ideal companion to our all-weather composite decking is our DuoSpan™ subframe system.

DuoSpan™ combines the strength of aluminium with the design flexibility of recycled plastic. This combination enables distinctive design opportunities for decking and outdoor structures that would be impossible with most conventional subframes. Boasting impressive durability and exceptional ease of installation, DuoSpan provides the perfect subframe for Millboard decking, as well as a universal support system for other outdoor flooring. Its ingenious design includes multiple features that make it near-impossible to get assembly wrong.
DuoSpan™ combines the strength of aluminium with the design flexibility of recycled plastic. This achieves a system that provides exceptional ease of installation, enormous strength and durability. DuoSpan has been designed by industry professionals to comply with Eurocode 1: Actions on Structures (BS EN 1991-1-1). The system has been assessed for point loading in relation to both domestic and commercial use, making it suitable for a range of applications.

There may be situations where our Plas-Pro framework items may be more suitable than the DuoSpan, such as furniture framework or areas in wet/marine environments. Manufactured in the UK from 100% recycled plastic and they will never suffer from insect attacks or rotting, they are designed for longevity and reliability
Following extensive trials, we recommend and supply Durafix® stainless steel screws, designed specifically for Millboard - this is a requirement of our limited warranty. There’s no need to pre-drill or countersink Millboard decking, and the unique Lastane® material coating flexes back over the screw-heads, leaving a minimal witness mark. This may be more visible on the lighter colours. Should some of the screws leave larger witness marks, these can be filled - please see our installation guide.
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.
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 boards.
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. 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.
