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.

What subframe do I need?
What subframe do I need?
If you are requiring a composite subframe for your decking and it's going over concrete, then the best frame for this is the DuoLift Joist Pedestal
To work out how much you need; take your square meter area, let's say 12m2.
12m2 x 1.5 joist size (50x50) = 18 no of joists
Pedestal 5no per m2 - 5 x 12m2 = 60 (10 in a box) so 6 boxes required
Hexhead screws 1 box covers 8m2 - 12 divide by 8 = 1.5 boxes, round up to 2 boxes.
If you are needing a frame to go over virgin ground i.e. soil, then the Plas Pro sub frame system - uses 12m2 as an example again.
Frame post - 12m2 x 0.2 (size of post 100x100x3200mm) = 2.4 round up to 3
Frame joist - 12m2 x 1.6 (size of joist 125x50x3000mm) = 19.2 round up to 20
Hexhead screws 1 box covers 8m2 - 12 divide by 8 = 1.5 boxes, round up to 2 boxes.

What's the difference between timber joists and plas pro/duospan joists?
What's the difference between timber joists and plas pro/duospan joists?
Timber is the most commonly used subframe material. However, timber only performs well under ideal circumstances and if the cut elements are regularly retreated. In applications where the timber is in contact with the ground or has limited airflow, the intended lifespan of the frame can be impeded significantly. Our recommendation is to use our innovative DuoSpan framework or Plas-pro to achieve a non-rot solution.
If you prefer to use timber as your subframe we do also stock the Walther Strong decking tape to give the joists an extra layer of protection
What fixings should I use to fix Millboard decking?
What fixings should I use to fix Millboard decking?
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.
Product Features & Maintenance
Are Millboard decking colours consistent?
Are Millboard decking colours consistent?
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.
Does Millboard decking get hot in the sun?
Does Millboard decking get hot in the sun?
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.
Does Millboard decking mark?
Does Millboard decking mark?
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, this also applies to cooking oils or fats that come into contact with the surface of the Lastane®.

My boards have just been laid & have a slight oily/shiny finish?
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.
Orders & Returns

I've got some boards and other bits left over, do you accept returns?
Unfortunately we cannot accept returns at this time. We would recommend you either order as close to the number of boards as you think or if the order is very large, maybe under-order and book a second delivery. It's easy to deliver an extra board or two.
