Millboard The Product Made in the UK

Article supplied by TimberPlus


Millboard is made from polyurethane, resin, recycled materials and fibres with a lastane® very high anti-slip, hardwearing coating.

Polyurethane is an extremely durable lightweight material with very little reaction to external elements, like moisture, temperature and ultra violet light.

Product Benefits:

The 3 key benefits of Millboard decking are as. Follows:

  1. Maintenance Free- Does not contain wood flour or plastic, which are protein Based & assist in the growth of algae.
  2. High Slip Resistance- Lastane coating which is a very high anti-slip material, giving a wet PTV slip resistance up to 55-81 depending on which style is used.
  3. Minimal UV light degradation- Tested for up to 5000 hours (equivalent to10-20 years). Colour change negligible also added to this, it is … 

More benefits:

  • Stain and mould resistant, none porous: Dirt, drinks, food fats etc. Won’t be absorbed into the board making it a near zero maintenance decking board. 
  • Minimal expansion and contraction, is under 1%, so closer joints can be achieved = safer deck or boardwalk. 
  • Non abrasive anti-slip finish – high anti-slip even in the wet ! (The only composite decking that exceeds the requested wet anti-slip ratings for public areas) Impact resistant. (All boards are fibre re-inforced)
  • Algae resistant – Non-porous, resisting algae growth (rain will wash it off) = ant-slip and near zero maintenance. No wood fibres or rice husks to support mould or algae growth.
  • Non Rot - Millboard does not contain any substance that will rot or can be eaten by insects.
  • Fire Classification - Inherently self-extinguishing, doesn’t support a flame. Indicative tests using underwriters UL94 Test standards, Samples passed V2 Test Criteria.
  • Environmentally Friendly - Uses up to 50% reclaimed fillers, Base material properties are excellent, Ozone Depletion Potential (ODP) = 0 Global Warming Potential (GWP) = 0
  • ‘Lost Head’ screw fixing - Screwed down with a 4.5x70mm Stainless steel trim-head screw, giving a hidden lost head effect. This creates a cleaner looking finish making it aesthetically more appealing.


Why Millboard over against WPC* or timber?

*Wood, Plastic Composite

Wood plastic composites

  • Unrealistic looks, sometimes with a rolled in grain type repeating pattern.
  • WPC is made from a mixture of wood and plastic, which are booth protein, based and Assist in the growth of algae making the deck slippery and needing regular Maintenance.
  • Because WPC contains wood it absorbs water and swells, which added to, the fact plastic is affected by temperature means you get large amounts of expansion and Contraction.
  • WPC can stain as a result of fizzy drinks red wines, food fats and sauces being spilt on it.
  • WPC manufacturers admit it will fade quite substantially by up to 10% to start with and can soon look quite bleached out.
  • WPC is made with high-energy process, which takes roughly 6-29MJ/Kg of energy in manufacture making it possibly a high emissions product.
  • Often they don’t give a very good slip-resistance in the wet.
  • Timber rots, splits, splinters, fades, and gets slippery, needing constant increasing Maintenance and stains very easily.

Millboard decking

  • Millboard is the most realistic composite decking in the world.
  • Contains no protein based products and its non-porous surface makes it resistant to the growth of Algae making the need for maintenance nearly zero.
  • Polyurethane has extremely stable characteristics with an expansion and contraction rate of under 1%
  • Because of its non-absorbent character it does not stain as a result of fizzy drinks, red wines, food fats and sauces being spilt on it.
  • Millboard has been UV fade tested for up to daylight 5000 Hrs (10-20 years) little change showed.
  • The millboard decking UK manufacturing process is a very low energy process requiring around 2-6MJ/Kg of energy thus reducing potential emissions.
  • Millboards Lastane® coating makes it one of, if not the highest anti-slip Composite decking products in the world.
  • Added to the above millboard wont rot, split, splinter, has a very low maintenance level.



Installation : 

Project Setting

  • Residential/light Commercial: Joist centers set at 400mm.
  • Heavy Commercial/ Raised terraces & Balconies: Joist centers set at 300mm
  • Chevron / laying @ 45 º : Joist centers set at 300mm
  • Board Spacing: 4mm on the sides and 2mm at the ends is recommended. Maximum 50mm unsupported decking board overhang.
  • Cutting & Working: Standard wood working tools and power saws with TCT blades.
  • Fixing: Through the surface with Durafix 4.5 x 70mm St/St screws and set the head 5mm below the surface. 2 screws to be used where a board crosses a joist. 3 Joists per cut board.
  • Step Edge/ Fascia: Bullnose or ribbed stepedge profiles are used to finish the cut edges or step nosing’s at the edge of a curved or straight deck or step area.
