Wood vs. Fire

Can one prevent wood from firing up?


There are several methods to amend fire reaction of wood which delay its natural ability to ignite and spread smoke. They are called fire-retardant treatments. Timbers then become fireproof or fire-retardant.

Timbers can be more or less heavily treated, and at the end can match normalised classification standards.


Is there any naturally fireproof wood species?



There is no natural fireproof timber. Wood is an organic material and it burns. Yet, some species are known beign more easily flammable than others. It is taken for granted that 14mm+ thick hardwood have a better fire reaction that softwoods of the same thickness. Some heavy tropical woods or some carrying specific chemicals might burn slower than regular woods and match a particularly good fire reaction. Nevertheless, no non-treated wood can naturally reach the Euroclass B performance.



Which species can be fireproof treated?

Every lignocellulosic material can technically be fireproof treated: wood, bamboo, rattan, hemp, palm tree... Thecnologies and features may vary according to the nature of the material.

Woodenha runs their own dedicated production line: the autoclave has been specifically designed and set for fire retardant treatment under high pressure. It allows high retention rate of the fire retardant product in the material even into hardwood. As the quality of the fire retardant treatment depends directly of the quantity of fireproof agent kept in the timber, each batch of wood that goes in is weighed before and after treatment.
