Among the exotic tree species, ireko grows in the African rainforest. It is one of the most valuable tree types in the world. This tree has high resistance to decay and fungus formation and is used for poolside, sauna and bathing. This tree, which can be used almost everywhere, is mostly preferred on surfaces that come into contact with water. Especially suitable for making boats. Ireko tree is also often preferred on the deck of ships. This wood material, which does not have an oily structure, changes color in time. While it has a yellow color for the first time it becomes dark brown as time progresses. This darkening is only related to the change in color. It does not mean deterioration on the surface used.
