Description
The PX3-0 XpressClad Ventilated Rainscreen is an express jointed, cavity-based cladding system that incorporates an aluminium rail support system to achieve a 20 mm cavity depth. The cavity is drained and vented at every horizontal junction / joint. It is designed to be used as an external cladding system for residential and light commercial type buildings.
The PX3-0 XpressClad Ventilated Rainscreen features fibre cement panels referred to as Swisspearl and Pacbld Refined, or wood fibre laminate panels referred to as Parklex. Panels are fastened to aluminium rail supports with either an adhesive fixing system, or a combination of adhesive fixing and mechanical fasteners, dependent on the installation height above ground level.
The cavity system 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 20 mm cavity. The cavity allows for any occasional ingress of water that may get past the external skin to drain to the exterior of the building, and any remaining moisture to dry by evaporation.
