Rear Ventilated Facades
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 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 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 rainscreen cladding system contains open or covered 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.
A differential between the temperature on the face of the cladding and the temperature of the air cavity creates a variation in air density, resulting in a ‘chimney effect’ that produces upward airflow within the cavity. Reducing humidity and increasing the efficiency of insulation, rear ventilated facades don’t suffer from mould, fungi and rot, making them extremely durable and virtually maintenance free.
The rainscreen cladding system does not allow water droplets to penetrate the structure but, as a safeguard, a weather resistant membrane is attached to the building frame. Under extreme weather conditions a minimal amount of water may pass through the joints but, 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.

Rear Ventilated Facades with their inherent airflow provide several distinct advantages over other facade systems;
- Thermal Efficiency
- Acoustic Insulation
- Environmental Protection
- Energy Saving
TRESPA Fixing Systems:
TS200 – Mechanically Conceal Fixed
TS700 – Direct Fixed with Colour Coded Screws
Swisspearl Fixing Systems:
Swisspearl Facade Panels are installed on Timber or Metal substructures.
The fastening method using “visible” screws or rivets allows an efficient attachment to the supporting structures. In fact, the fastener heads are available in the same shades of colour as the panels, and are hardly visible even a slight distance away as they blend with the overall surface
SIGMA | Concealed Panel Attachment
The concealed attachment has been designed for applications with the highest aesthetic standards. This high-end method of use brings out the full attractiveness of the surface finish of the Swisspearl® panels.
SIGMA concealed panel attachment is available for
8 and 12 mm panel thickness.
The panels are supplied from the factory accurately cut to size, including anchoring points to the panel rear face. Aluminium parts are fitted to the panels on site and the panels hung into the appropriate supports on the sub-framing.
The sub-framing is made either out of timber battens covered by a layer of EPDM for moisture protection; or by metal, i.e. aluminium or galvanized steel.
Metal Sub Frame (aluminium or galvanized steel)
Sub Frame | Panel Supports
The panels are supplied including the fasteners but without the support
profiles. This leaves the great advantage of flexibility for architect or customer with 2 options:
- Sub frame made from standard hat and Z profiles (cost efficient)
- Sub frame system (there are many products available)
