In fibre cement there is a fibre reinforcement, which contributes to making the fibre-cement material even stronger. Together with a carefully planned production process, fibre cement makes it possible to develop strong and long lasting construction materials.

Today fibre cement is considered as a material physically suited for construction products such as cladding and roofing. It is primarily due to its function, performance and commercial value.

Fibre cement flat sheet classified, by accredited laboratories, as Category A according to BS EN 12467: 2004 Fibre-cement flat sheets – Product specification and test methods are sheets which are intended for applications where they may be subject to heat, high moisture and severe frost. 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 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.
