Wood offers exceptional conditions in the manufacture of different products for construction, however 4 centuries ago there were no advanced processes. It is here where the Japanese were pioneers in this technique that today became popular around the world. charred wood. Today in Facades World We tell you all the details so you know the latest in construction. Let's see…
How the burnt wood technique was born
Japanese carpenters were looking for a solution for the use of wood improving its durability and giving a new look of beauty, especially to improve the resistance of wood in coastal areas where saltpeter and humidity spoiled the wood in advance.
Thus was born a technique called burned wood in Japanese (焼 杉).
The burnt wood technique consists of three steps:
1- Three long boards are joined making a triangular shape with a material resistant to combustion and fuel is introduced inside. Combustion begins so that the wood is burned inside that triangle.
2- After 7 to 10 minutes or when the wood has been charred in 3-4mm thickness, the boards are separated and the combustion is stopped with water, allowing it to cool.
3- The charred face is brushed and sanded and natural products such as oils are applied to protect it.
Historically, in the Japanese territory, the traditional technique was being replaced by the application of other materials, such as polymers, stones and aluminum, in order to combat natural pests. However, Fujimori was the one who popularized the technique beyond the limits of Japan, making architects from different parts of the world appropriate it, reinventing its applications and its composition.
