Fire retardant

The threat of fire must be considered in any new construction project, and the fire performance of the cladding system must be compliant with the local building regulations relevant to the building’s intended use.

Unlike some other materials and composite panels, the behaviour of timber in the event of a fire is very well documented and understood, and is predictable in terms of its reaction to fire. Consequently, timber cladding can often be classified under the Classification Without Further Testing [CWFT] rules of EN14915, where many timber species and cladding arrangements can be categorized as Euroclass D. In line with building regulations, this means that timber cladding can often be used in a wide variety of situations without further treatment.

For certain building types, and in certain situations (eg close to a boundary/fire escape etc), local building regulations may stipulate a minimum reaction to fire class C or B, which can be achieved with timber cladding by means of impregnation with a flame retardant when installed correctly.

Our cladding sales team can advise you further about the most appropriate system for your project’s individual specification, however it is vital that you check that the product being considered is suitable, and that the full specification of the cladding and associated elements is compliant with your local building regulations. If you are in any doubt, please speak with your building control officer.
