General Information

What is Bamboo?

Bamboo is organised according to the botanical standpoints of the types of grass and also according to their chemical composition considering the wood quality. The main components of bamboo are about 70% Cellulose and around 25% Lignin. The prominant difference between this type and the other usual products is the fast growth of the bamboo plant itself. Tropical bamboo plants reach a height of 1.20m in only 24 hours. On the other hand the "Phsyllostachus Pubecsens", known for its extreme hardness and marginal source points that makes it user friendly for parquetts, reach a height of 30cm per day. This goes to show the strong characteristics of the bamboo. For centuries, it has been highly appreciated and used as a quality woodform in asian regions.

Bamboo planks

Bambus counts as one of the fast growing raw materials in the world. They can grow up to one meter in 24 hours. Bamboo produces four times more wood than oak. It also gives more oxygen to the atmosphere, thus serving the ecosystem and also averts deforrestation, as it produces and spreads in dense clusters rather than individual offsprings.

After removal of the outer knots, the bamboo is sorted, split and then the inner knots are removed. The produced strips are dried inside a chamber and carbonised eventually. Next the strips are pressed and glued into proper planks. Some processes are still done manually. The right type of bamboo, the age and time of harvest as well as the adhesion and drying procedure play an important part in the quality of the finished product.

As a building material, bamboo has nothing to worry about when it is compared to other types of wood. The fiber of bamboo are upto 1 cm long whereas the other original woods account for only 2 mm. But bamboo consists of only little amount of the material Lignin. The main component is silica. This gives the blade long-lasting resistance and hardness Additionally bamboo is highly resistant to fire and chemicals.

The bamboo stripes can be colored darkly (carbonisation) and thus interesting patterns are possible on the plates. Parquett elements can also be build from the bamboo. The upper surface is much stronger than the oak and birch.

Bamboo can also be used as a substitution of veneer. Thin stripes of bamboo are glued together on thin paper (lamination), which then is processed just like any other veneer.
