By using suspended Wallbarn Timber Paving Tiles, installers combine the natural, attractive finish of timber decking with the speed and ease of laying paving slabs.

Traditionally laying timber decking directly onto these deck surfaces led to additional costs of employing specialist carpenters. Laying timber joists directly onto the waterproofing membrane also risked damage over time. Wallbarn Timber Paving Tiles offer the ideal solution. The weight of the tile will hold the system in place.

This suspended system avoids having to fix anything onto the deck and lifts all the timber away from any standing water, avoiding the dangers of a slippery surface.

As everything is free standing, the tiles can be taken up and replaced without disrupting the whole area, should the deck need to be inspected. Unsightly items such as drainage outlets, cables and pipes can be hidden beneath the tiles and accessed easily.

Stunning finishes can be achieved. The tiles can be laid in a straight line pattern or in a “chess board” style, depending on the client’s wishes. We have a range of different timber available sourced from South America, chosen for their beauty and durability including Ipe and Cumaru. We can also supply FSC® certified timber as we have FSC® Chain of Custody (please speak to your Wallbarn representative).

See our gallery for more pictures of Hardwood Timber Decking Tiles.

They are laid in the same way as regular concrete paving slabs, suspended on Wallbarn’s ASP range of support pads. The four positioning lugs on the head of the support pads allow rainwater to drain in between each tile then flow underneath into an appropriate outlet. This avoids the risk of standing water creating a slippery surface or causing the wood to rot.

They are suitable for any type of flat roof design or membrane, and will not be affected by wind uplift due to the gaps between the slats. They can be used in conjunction with concrete slabs or natural stone.



Wallbarn selects timber of the highest quality. All species are extremely tough, will not absorb water, rot or become covered with fungus or mildew – ideal for the British weather. The tiles are manufactured to the highest quality; with the timber being kiln dried and the tiles are fixed together with rust-proof screws and an extra plank of wood on the underside to reinforce the tile. They are all treated with natural oil lacquer. 

All our timber possess the following:-

  •  Are ultra-hard and dense
  •  Are long lasting
  •  Are resistant to moisture ingress and rotting
  •  Have smooth grains that are unlikely to splinter or scratch on the surface
  •  Are resistant to insect and mildew damage
  •  Are strong and weight bearing.

We have a number of different species available, both as stock items and non-standard material for specific projects. The main types of timber used are:-

Ipe from Brazil is one of the toughest most durable woods available. It has a greenish brown appearance and because of its tight grain is recognised for its high resistance to mildew, termites and rotting. It is very low maintenance and is used extensively in marine and exterior construction due to its resistance to water. It dries very well and becomes extremely hard, which means it has to be pre-drilled and cut with a mechanical saw. It carries a Class A fire rating and will last well over 25 years. It is nicknamed “ironwood”.

Cumaru is another hardwearing timber from Brazil. It is similar to ipe and sucupira and has a rich chestnut colour. It has very good strength and rot-resistant properties, but is not as resistant to insect damage as the ipe. It is an ideal timber where clients favour a lighter-coloured wood finish.



We are able to source other timber styles as non-stock items including:

  • Green Heart, a very tough moisture resistant timber from Surinam. It has a yellowish colour.
  • Garapa has slightly lower mechanical properties but still a long lasting, hard-wearing timber, slightly yellowish/beige in colour, which will last for over 15 years.
  • Sucupira is an extremely hard-wearing chestnut-coloured timber, not quite as strong as Ipe but still ideal for external decking. 

Please check the website for regular updates on new species of timber available or contact us for any specific requirements. Wallbarn has access to a large number of growers and forest managers and are confident we can meet your requirements.


The timber can be cut into shapes to fit around details and corners in a similar way to concrete slabs, which help to achieve clean finishes to the edges of terraces. Light fittings can also be fitted into the tiles creating a very attractive mood and look.

Because Wallbarn selects superior timber, the grain is smooth and uniform, making sawing and drilling straightforward. However, due to the density of the timber, mechanical sawing and drilling is essential.

We recommend that carbide tipped saw blades are used when cutting the tiles. Saw blades will become blunt very quickly when working these types of timber. Wallbarn recommends pre-drilling all holes before screwing into the wood to avoid splitting.

Border planks are available in the same type of timber as the tiles. The edge of the tiled area can be secured by fixing the border planks to the sides of the tiles with screws. The tiles are held in place and prevented from moving, and the area is finished off neatly. The planks are available in a number of different sizes, with both square and rounded edges, depending on the client’s preference.

Wallbarn has a great deal of experience with roof deck finishes and support systems, and has supplied hardwood timber decking tiles for a wide variety of installations, from small roof terraces on domestic projects up to largescale walkways and public areas in a number of different species of timber. Please contact us with your specific requirements and we help you select the correct design and product.

Wallbarn has FSC® Chain of Custody certification and can supply FSC 100% certified timber.

This scheme aims to monitor and control the whole process of timber growing, so that all timber used is sourced from well managed forests.
All certified timber can be traced back to the well managed forest it was felled in. Every party, from the grower to the processor to the manufacturer of the tiles to the end user is tracked and audited to ensure that they have complied with the practices laid down by the FSC.

FSC® 100% Chain of Custody certified timber – number SGS-COC-007242

Only fully accredited members of the Forest Stewardship Council are given a number and can use the official FSC® logo against FSC® certified timber only. This timber is clearly distinguished and marked as separate from non-FSC timber and the mark can only be used with FSC® certified material.

For more information please go to the FSC website – http://www.fsc.org

The tiles are manufactured with a reinforcing bar on the underside made from the same timber as the top layer. All the fixings are made with rust-resistant screws to achieve optimum performance.
