Yoroi
by Zwarthout | Shou Sugi Ban · Netherlands · ONA986 · Published 19 Sept 2023
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 Zwarthout’s oven. 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.
Yoroi has a fire class B-S1, d0, fully tested according to the European standard EN 13823 (SBI) and EN-ISO 11925-2. Values obtained FIGRA 0,2MJ W/s: 21, THR600s MJ: 4.5.
Yoroi also has a LCA certificate.
