Rainscreen Cladding

Rainscreen cladding is an exterior wall construction method that utilises an outer layer (the "rainscreen") to shield against water penetration while permitting the walls to "breathe" and dry out. 

Typically, it consists of an outer layer of cladding material (such as metal, fibre cement, or composite materials etc) separated from the underlying wall structure by an air gap. 

This air gap, combined with drainage channels and ventilation, helps prevent water from infiltrating the building while allowing any water that does enter to evaporate and escape.
