Fire Attenuation Screen

MicroLouvre fire attenuation screen achieves industry leading 49.4% attenuation achieved when tested at CSIRO. Bush fire screen protection in accordance with AS3959 <2mm between louvres.

Greene Fire are industry leaders in fire attenuation screens, a specific type of MicroLouvre. Our fire attenuation screens achieve an industry leading 49.4% attenuation when tested at CSIRO. In addition to this, our fire attenuation screens also provide bushfire screen protection in accordance with AS3959 <2mm between louvres.

MicroLouvre, the most efficient solar shading product, has now been tested and proven to have market leading fire performance as a fire attenuation screen. The specially angled, bronze louvres are the perfect solution for reflecting heat, as was shown by the industry leading 49.4% attenuation achieved when tested at CSIRO. This ensures floating embers, naked flames and radiant heat do not pose an ignition risk to your property. Given the increasingly high densities city-dwellers are living and working in, protecting buildings from fire is more important than ever.

Not only does MicroLouvre provide the highest amount of fire attenuation, it also has twice the open area of other screens. This makes MicroLouvre almost invisible from the inside, giving perfect outward vision.

Used as a fire engineered solution to protect openings close to property boundaries, make sure to specify MicroLouvre Fire Attenuation Screen to get the most benefits for your building.

Bushfire protection

MicroLouvre fire attenuation screen is compliant to AS3959 for use as a bushfire screen to windows. The louvres are spaced less than 2mm apart, making the screen equivalent to the requirements for screening in the Australian bush fire design standard.

Don’t compromise!

• Get the best fire attenuation
• Get the best solar shading
• Get the best visibility
• Get the best ventilation
• Get total shading

Fire attenuation screens are usually compared by the percentage that the screen reduces heat. This means that 49.4% attenuation would reduce the heat at the location of the screen by 49.4%. This sounds simple enough, however, testing and proving this is not so straightforward.

As there is not a standard test methodology, some claim the percentage attenuation as the reduction in heat at the screen, measured 365mm behind the screen. In reality, the heat has already reduced even without the screen in place at that position!

Where would a MicroLouvre fire attenuation screen be used?


rapid rate
The population density within our cities is growing at a rapid rate. This means that we are constructing our buildings closer to the property boundary and each other. Class 2 to Class 9 buildings that are built within 6 meters of the property boundary require fire protection to the external walls, with fire attenuation screens being the ideal solution.

Openings in the external walls are required to be fire protected in accordance with C3.4 of the NCC. The options include using 60-minute fire rated doors, fire windows, fire shutters or external wall wetting sprinklers.

MicroLouvre fire attenuation screens offers a cost-effective alternative to the NCC Deemed-to-Satisfy (DTS) requirements.

A fire engineer can use the extensive testing and high performance of MicroLouvre fire attenuation screens to determine a design where the building can withstand a minimum heat flux in accordance with Verification Methods CV1 and CV2 as defined in the NCC.

Installing MicroLouvre fire attenuation screens to your Class 1 building (domestic dwellings) meets the requirements for screening in bushfire areas as required in AS3959-2009 up to BAL-40 & BAL-FZ.
