Wood is combustible but this does not mean that its use as a construction material will create an unacceptable fire risk.
Frequently the opposite is true; its good thermal insulation properties, high structural strength and slow charring rate, mean that wood in large sections can often be used unprotected. In comparison, materials regarded as non-combustible like steel, would require special fire protection to prevent premature collapse in a fire.
The increasing use of wood in smaller cross sectional sizes and panel products has seen an increase in the need for enhanced fire performance. This can be provided economically and effectively by a flame retardant treatment factory applied under controlled conditions. The result is a material that will comply with the most stringent fire protection building regulations.
