Description

The PRIMAflex™ Cavity Wall Cladding System is a cavity-based monolithic sheet wall cladding.  It 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 Wall Cladding 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 or timber battens 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 20 mm cavity.
