Increased fire protection
Flaming the wood surface closes the internal cells of the wood, which has a positive effect on the fire-resistant properties. In other words, wood that has once burned and has a charred layer on its surface is much more difficult to set fire to again.
The burning of soft layers of wood makes the wood naturally resistant to flames, and by burning cellulose, only the surface remains on the wood, which requires a much higher temperature to ignite than in the case of raw boards.
In the past, when fires happened much more often, and the fire consumed the often makeshift buildings based on wooden structures in the blink of an eye, efforts were made at all costs, using all possible means to progress in the art of construction. Paradoxically, it turned out that the fire consumes burnt beams and boards much slower, and the earlier burning slows down the burning process and gives more time to react appropriately.
Currently, a lot of attention is paid to fire protection, modern construction also looks completely different, and most of the raw materials and building materials are produced in a way that reduces the risk of fire. Nevertheless, the technical characteristics of the Shou Sugi Ban wood remain timeless, and the use of fired Wood of Fire Shou Sugi Ban boards contributes in a particular way to the increased fire resistance of the entire building. In light of the current regulations, most public buildings should meet the fire resistance requirements specified in the NRO standard. In the case of Shou Sugi Ban boards by Wood of Fire, it is possible thanks to the possibility of using special, certified fire retardants for an additional fee.
