orginates from the forests that grow in the Congo Basin in Gabon



Kosipo is available in the forests of Precious Woods, located in the Congo Basin of Gabon. The tree attains heights up to 40-50 m and diameters up to 250 cm. The trunks are straight and cylindrical and have buttress root boards.



Freshly sawn Kosipo has a brown to dark red brown color, with a purplish glow. It is somewhat darker than Sipo and can be used as a substitute. The 20-50 mm thick sapwood has a dull grey color and is easy to distinguish. The wood structure is straight and interlocked. The timber contains some resin. The texture is medium coarse.


Processing properties

The machining of Kosipo can be done easily, altough it contains Silica, which has a blunting effect on the tools. Therefore hard metal tools are advised. Pre-drilling is recommended. The gluing and finishing properties are good. It dries rather slowly, and requires care to prevent severe cracking and deformation.



Kosipo is mentioned on the SKH publication 99-05 which means that the timber is approved for production of KOMO certified door and window frames, doors and windows. Furthermore it is also used for façades, as a substitute for Sipo and Sapeli, interior uses like panelling, furniture, stairs, parquet and yacht construction.
