NBT-Approved Fire Retardant Treated Wood Products with Documented Properties 

There are many different types of fire retardant treated wood on the market. Fire protection resistance's durability in various applications, especially in humid environments, however, can vary a lot between different brands. New Nordic and new European systems of class for fire retardant treated wood and fire class for wood has therefore been introduced, refer to the section on new classifications for fire retardant treated wood.

This page presents wood products with documented properties for both fire class and classes for fire retardant treated wood. For outdoor use (Use Class EXT) there is normally a need for protective painting, which works in conjunction with the fire retardant treated wood product.

The user is responsible for ensuring that the product is used in the right way and the right place in the present case and that the product meets the standing requirements for fire resistance. Fire requirements are set nationally and vary between the Nordic countries.
