Thatched Roofing

LOMBOK Alang Alang Thatched Roofing for Export

Traditional alang alang construction

Alang alang thatching has been used in Indonesia for hundreds of years on the islands of Bali, Lombok, Sumbawa, Timor and Sumba as a traditional system of roofing. There are slight variations in the application of the material throughout these different places but by far the neatest and strongest form is found in LOMBOK

The blades of alang alang thatching are constructed from the grass Imperata Cylindrica which is called locally RE. It is also called alang in Indonesian and Malay. It is known in Australia as bladey grass because of its tendency to cut skin. It is a tough and resilient grass and grows best in harsh conditions and poor ground. Some of the strongest examples are found on sandy margins at the edge of beaches and on cliff tops. Because of the demand for alang alang for tourism projects in Bali and Lombok and the loss of the beachfront margin to hotels, there has been a lot of grass production in fertile soils that were normally used for other farming, also using fertilizer to allow faster harvesting. The alang alang made from this raw material is inferior which shortens the lifespan of the roof material.

Traditionally, the batten used to form the spine for the pieces that are laid onto the roof was a strong, small diameter bamboo, but because of the difficulty getting supplies of this material the practice now is to use split pieces of larger bamboo. This change has affected the form of the blades of grass as they wrap around the batten, causing right angles rather than a smooth curve. This also shortens the lifespan of the roof material and also produces an unattractive, irregular and untidy finish. In addition, and most importantly, this split bamboo is very prone to insect attack as it still has a lot of bulky cellulose that is exposed by splitting the bamboo.

Currently, the fabrication of each length of alang alang is still done in the same traditional way as before. The worker selects a bunch of grass approximately one meter long and wraps 150 mm of the base of the bundle over the batten. A small split bamboo is laid about 50 mm down from the batten, parallel to the batten and at right angles to the blades of grass and the bundles of grass are progressively lashed to this using a continuous length of either black ijuk twine or twine made from bamboo. The traditional length of one piece of alang alang is three meters.

Balinese roofs are commonly, but not always, made with bamboo rafters. The alternative is timber which is more expensive. The rafters for alang alang roofs have additional short rafters, set at a lower pitch, overlapping the bottom end of the main rafter. This creates a slight upward lift to the roof at the eaves. Both the main rafter and this additional rafter are finished with a bamboo or
