Appraisal number: 997 (2017)

Date issued: 20 Dec 2017


Shera Weatherboard Cavity Cladding is a cavity-based fibre-cement weatherboard wall cladding. It is designed to be used as an external cladding system for residential and light commercial type buildings where domestic construction techniques are used.

Shera Weatherboard Cavity Cladding consists of Shera Weatherboard, a bevel-back fibre-cement weatherboard which is fixed over timber battens to form a cavity. The cladding is finished with a latex paint system.

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 nominal 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.
