Sipo

Sipo, botanically Entandrophragma utile, also known as Sipo mahogany or Utile, is now traded as Sipo in accordance with DIN EN 13556. Originally imported from West Africa, the wood was in high demand in Europe in the 1960s and 1970s. However, resources are declining, which is driving efforts towards sustainable timber procurement with recognized certification systems. Entandrophragma utile, a deciduous tree, reaches heights of 55 to 65 meters and trunk diameters of up to 3 meters. With a straight, cylindrical trunk and a knot-free zone up to 40 meters high, the tree has a dome-shaped crown. The bark is fissured, silver-grey to brown, while young twigs are short-haired and brownish. Sipo is known as a highly valued wood for furniture and construction applications, but the current challenges in resource availability demand increased efforts for sustainable use.

Sipo also impresses with its characteristic wood, which is ideal for decorative applications. The sapwood is reddish-grey and stands out clearly from the light to brownish-red heartwood, which darkens to a deep reddish-brown during the drying process and through natural light aging. With a durability class of 2-3 according to DIN EN 350-2, Sipo is considered to have good to moderate resistance to wood-destroying organisms. The structure is characterized by fine pores, alternating growth and narrow parenchyma bands. Sipo is easy to work with and is suitable for furniture, paneling, parquet flooring, boat building and as construction timber for interior and exterior applications. Care must be taken during drying to minimize the risk of warping and cracking. Sipo is an ideal choice for high-quality interior fittings and construction projects, from boat building to window and door frames.
