Internal Fire Retardant Treatments

Sentrin FRI fire retardant treated timber has been pressure impregnated with a humidity resistant, (WPA Type HR), high temperature fire retardant formulation, Osmose FirePRO. It has been processed under ISO9001 controlled factory conditions to provide confidence in performance and long lasting protection without further maintenance. Treated timber can meet the requirements of national Building Regulations where Euroclass B or C are required and will significantly reduce the spread of fire, heat generation and smoke generation. These fire performance properties do not compromise critical engineering properties such as strength, durability, corrosivity and hygroscopicity.
