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 has a number of different types of wood to suit different budgets and installations. We are currently selling hardwoods - Ipe, Cumaru and the softwood Cedrinho (also known as Cambara or Jaboti) timber.
All the timber is made from ethically sourced Brazilian timber, from sustainable forests. Wallbarn have chosen timber from growers who have been planting dedicated forests specifically for timber harvesting over a period of 30 years.
All our timber complies with the Brazilian Government extraction and handling regulations called IBAMA. This scheme controls the planting and harvesting of all timber in Brazil. All the timber is issued with a Certificate of Origin - Documento de Origem Florestal (DOP) before it is exported.
Full details of the regulations and compliance procedures, as well as relevant documentation can be found by contacting Wallbarn.
This timber has been specifically chosen because of its long life span and attractive finish. The Ipe and Cumaru were chosen because they are very tough, and will not absorb water, rot or become covered with fungus or mildew – ideal for the British weather.
All the tiles are manufactured to the highest quality; with the timber being kiln dried and sawn and made into tiles by the grower. The tiles are fixed together with rust-proof screws and reinforced on the underside. They are all treated with natural oil lacquer
Other types of timber, tiles sizes and finishes are available as non-standard items. Heavy duty tiles, as well as mosaic and diagonal designs can also be supplied.
They give a beautiful finish to roof decks and can be laid either in a straight line pattern or in a “chess board” formation, depending on the client’s wishes.
The timber can be cut into shapes to fit around details and corners in a similar way to concrete slabs, which help to achieve attractive finishes and edges to terraces. Some of the timber can be extremely tough and pre drilling with power tools may be required to drive nails and screws into it.
Edges and cavities under the tiles can be covered with border trims, in the same timber as the tiles. They are screwed into the sides of the tiles; and as well as hiding the cavity and sight of the support pads, also help to secure the whole system together, preventing any one tile from moving.
The edges slope gradually down to the deck level to give an attractive finish. Larger border edges are also available.
