Ideal for ultra-low thresholds

  • Our tiles are just 30mm in height which means combined with our 7mm fixed height pedestal you can deck up to a threshold as low as 37mm
  • Traditional decking methods using timber joists, even if suspended on a super-low support pad, will only allow you to deck up to a threshold of 130mm or higher




Just like laying slabs

  • Uniform size and space between decking
  • Unsightly items such as drainage outlets, cables and pipes are hidden beneath the tiles
  • Tile weight holds them in place
  • No need to fix anything to the deck
  • Futureproofed: take up a tile to inspect your deck with minimal disruption

Superior timber quality

  • Ultra-hard and dense
  • Long-lasting
  • Resistant to moisture ingress and rotting
  • Smooth grains that are unlikely to splinter or scratch on the surface
  • Resistant to insect and mildew damage
  • Strong and weight bearing


  • Tiles can be cut into shapes to fit around details and corners in a similar way to concrete slabs
  • This helps achieve clean finishes to the edges of terraces
  • Light fittings can also be fitted into the tiles
  • We select superior timber so the grain is smooth and uniform, making sawing and drilling straightforward


Note: due to the density of the timber, mechanical sawing and drilling is essential. We recommend that carbide tipped saw blades be used when cutting the tiles. Saw blades will blunt quickly. We also recommend pre-drilling holes before screwing into the wood to avoid splitting.

Border planks

Border planks

These 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
  • Planks are available in a number of different sizes, with both square and rounded edges, depending on the 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. See some of the projects we have supplied below.


We supply two types of timber tile, Ipe and Cumaru, species sourced from South America and chosen for their beauty and durability:

Ipe (Brazil) is one of the toughest most durable woods available.

It has a greenish brown appearance and because of its tight grain is popular 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 (Brazil) is another hardwearing timber.

It is similar to ipe but has a rich chestnut colour. It has very good strength and rot-resistant properties. Ideal for clients who favour a lighter-coloured wood finish.
