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.


What is a rainscreen facade system?

Combining multi-layer construction, the rainscreen facade systems consists of  rainscreen 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 facade systems for their building projects.

How does a ventilated rainscreen cladding system work?

A differential between the temperature on the face of the rainscreen facade 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 rainscreen cladding system contains open or covered joints with the ventilation cavity ensuring water droplets do not penetrate the rainscreen facade 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 rainscreen facade.

Rainscreen Cladding System At A Glance 



  1. Support structure – The exterior wall of a building is mainly made of concrete, CMU blocks, brickwork, steel or timber frame with studs and planked by gypsum boards.
  2. Sub frame – Facade panels are installed on timber or metal supports.
  3. Ventilated cavity – The main task of the air cavity is the evacuation of moisture and excess heat.   The air circulation occurs naturally thanks to the pressure difference between bottom and top.
  4. Cladding  –  The outer skin of the building envelope has two main functions; to be aesthetically pleasing as well as protecting against influences from climate and

Benefits of Rainscreen Cladding and Ventilated Facade Systems:
