Rear Ventilated Facades have been used extensively throughout the world over many years to provide a natural, energy efficient method for cladding commercial and residential buildings. A multi layer construction, the system consists of a rain screen cladding on the outer layer in combination with a frame, weather resistant membrane, insulation, sub frame and a ventilated cavity.
A modern method of facade construction, rear ventilated facades are gaining momentum in Australia as developers, architects and builders understand the principles and advantages of rain screen systems. A differential between the temperature on the face of the cladding panel and the air cavity temperature creates a variation in air density, resulting in a “chimney effect” that produces upward airflow within the cavity.
The rain screen system contains open joints with the ventilation cavity ensuring water droplets do not penetrate the system. As a safeguard, a weather resistant membrane is attached to the building frame, providing an envelope. Under extreme weather conditions a minimal amount of water may pass through the joints. Due to the ventilated nature of the system, this moisture will run down the back of the panel and drain out the bottom of the facade.
