Deeply charred bamboo, natural appearance, refined markings, fire class B

Product description

Yoroi’s hard carbon layer and refined markings take on a silvery glow in the sun.
The deeply charred bamboo has a natural appearance and was developed specifically for situations where fire class B is required, e.g. public buildings, high-rise buildings and escape routes. This makes Yoroi ideally suited as a sustainable façade cladding. Yoroi also stands out indoors.


Yoroi is made from FSC® thermally modified bamboo from China. Planks are made by compressing bamboo fibres.The bamboo planks are then individually charred by hand in our furnace. Yoroi gets an extra natural fire retardant through the charring. Therefore, no fire retardants are added that could leach out. No maintenance is required to maintain the fire resistance in the long term.
