How do fire retardant treatments for timber work?
When subjected to fire, the chemicals in both DRICON and NON-COM Exterior treated materials react with the combustible gases and tars normally generated by untreated wood, converting them to carbon char, carbon dioxide and water vapour. The insulating layer of char formed on the timber retards the process of combustion, reducing ignition, the rate of surface spread of flame and the amount of heat released, all providing additional time for the safe escape from the burning structure.
