Scope of Use

The PRIMAflex Fibre Cement Board is designed to be used as an external wall cladding system for residential and light commercial type buildings where domestic construction techniques are used.

The PrimaFlex Cavity System consists of PrimaFlex sheet, which is a fibre cement sheet product, fixed over timber battens to form the cavity. The cladding joints are finished with purpose-made jointers, timber battens or sealant and the system is finished with a latex paint system. The cladding incorporates a primary and secondary means of weather resistance (first and second line of defence) against water penetration by separating the cladding from the external wall framing with a nominal 20mm cavity.
