Fiber Cement Siding - Fire Resistance

Fire Resistance

Fibre cement cladding is a non combustible material which is widely used in high bush fire prone areas throughout Australia . Pictured above is James Hardie's Fiber Cement cladding ‘Scyon Linea’ weatherboard which has been substituted for the traditional timber fascia and barge board materials.

While the best possible Reaction to Fire Classifications are A1 (construction applications) and A1Fl (flooring applications) respectively, both of which mean "non-combustible" according to European standard EN 13501-1: 2007, as classified by a notified laboratory in Europe, some fibre cement boards only come with Fire Classification of A2 (limited combustibility) or even lower classifications, if they are tested at all.
