Taun comprises several hardwood species occurring in various parts of South-East Asia and the Pacific. Taun lends itself to general building construction and decorative uses.
Other Names: Malugai (Philippines), Kasai, Sibu (Sarawak, Sabah), Truong (Vietnam), Aia Fai, Mala, Ula, Ako Dawa (Solomon Islands), Tava (Western Samoa), Ahabu, Matoa (Papua New Guinea), Malugay, Akwa, Pometia Tomentose, Pometia Tomentosa, Pometia spp.
Taun comprises several members of the Pometia species occurring in low-lying coastal and riverine areas of Sri Lanka and South-East Asia, Papua New Guinea, the Solomon Islands and Samoa. Although the species can attain heights of up to 25 metres, an irregular bole and elliptical cross-section results in relatively short log lengths.
Taun heartwood varies in colour from pink to reddish-brown, darkening with age. Sapwood is a pale, pinkish buff, not always visually distinct from the true wood. The grain of taun timber is straight, with occasional interlocking, and of moderately coarse texture.
Taun is a moderately durable hardwood, with an above ground life expectancy of between 15 and 40 years. Its in-ground life expectancy is considerably shorter, at between five and 15 years. Taun sapwood is susceptible to lyctid borer attack and is very difficult to impregnate with preservative. Taun is not termite-resistant.
Uses of taun in construction include general house framing, cladding, fascia boards, internal flooring, and plywood. Taun's properties also lend themselves to decorative applications such as lining, paneling, joinery, cabinetwork, outdoor furniture, carving, turnery and veneers. It is also used for boat building and cooperage.

Taun heartwood varies in colour from pink to red-brown, darkening with age. Sapwood is a pale, pinkish buff, and not always visually distinct from the true wood. The grain of this timber is straight, occasionally interlocked and of moderately coarse texture.
Uses of taun in construction include general house framing, cladding, fascia boards, internal flooring, and plywood. Taun's properties lend themselves to decorative applications such as lining, paneling, joinery, cabinetwork, outdoor furniture, carving, turnery and veneers. It is also used for boat building and cooperage.
Taun is moderately hard (rated 3 on a 6-class scale) in relation to indentation and ease of working with hand tools. The timber saws and turns easily with only a moderate blunting effect on cutting edges. It is readily bored and holds nails and screws well, can be satisfactorily bonded using standard gluing procedures, takes paints and stains well, and can be polished to a smooth, high finish. While taun is reasonably easy to work, sanding dust may be an irritant to mucous membranes.
