TeakBecause Royal Botania make no concessions when it comes to quality, we only use carefully selected, fully grown teak, which is harvested in accordance with the strictest environmental standards. The wood comes from the Tectona Grandis, a tree that can grow to a height of 45m under the right conditions with a trunk diameter of up to 2.4 metres. The reason for its generally commended durability is the high levels of natural oils it contains. The resulting minimal moisture absorption prevents warping which gives it great stability. Moreover, the wood is extremely resistant to the influences of chemicals, as well as against attacks by vermin. Because of these qualities, combined with its exceptionally beautiful colour and structure, teak is classed as the most premium wood on the planet. The teak tree is predominantly found in the Golden Triangle, a region which covers Laos, Myanmar (formerly Burma) and Thailand. The qualities of teak were discovered several centuries ago and plantations were established in Africa, South-America and other South-East Asian countries. The condition of the soil and the climatic circumstances have an important influence on the quality of the wood. Only the Indonesian wood of the Tectona Grandis boasts similar qualities to those of the indigenous Teak wood. After the colonial era the Indonesian plantations came under the supervision of the local population and today are supervised by the Perum Perhutani government institution.
Only the mature wood has the excellent qualities mentioned, including stability and resistance. The tree is ready to be felled after 75 to 80 years. The trees are ringed, which means that the lower band of the bark is removed. The tree then loses most of its sap. About two years later it is felled and sawed up. The wood is then selected on the basis of its structure. Drying the wood is a very important phase and determines how it works later on. The time and speed of drying depends on the thickness of the material that needs to be dried. The drying-schedules must therefore be adjusted according to the filling of the drying kiln. Ideally the level of moisture lies be tween 8 and 12% after this phase, not only on the outside, but also at the core. Naturally, after the drying phase, further processing is important too. This is especially true for outdoor furniture because it suffers the most. In fact the strength of the construction is largely determined by the precision of the process. Bad timber joints with too much tolerance create instability and if the fittings are too narrow they can cause splitting.
Teak does not need additional protection due to its high resistance. Nevertheless it may be useful to treat the wood so that it is less prone to staining.
Tip we advise that the wood is allowed to become silver grey
