The AFC Defender system consists of a perimeter aluminium frame that can be powder coated a standard colour.
This is fixed to the perimeter of the window opening using a continuous angle. The mesh consists of a 0.9mm thick woven 304 stainless steel which is coated black to reduce the reflection of light and maximise the clarity of the view. The free area of the mesh is 42%.
Note that the angle of the light relative to the mesh may reduce the light into the room more than expected.
AFC Defender Screen provides radiation attenuation to protect windows close to a boundary [Class 2-9] or to provide BAL FZ performance to AS3959-2009 for Class 1, 1a & 10 construction.
Fire Engineers must use this data in their design and calculations to determine whether the radiation attenuation is sufficient to prevent non-piloted ignition and therefore fire spread to nearby materials/buildings.
AFC Defender - Radiation Attenuation Screen Specially developed for Fire Engineers and Architects to be used in lieu of deemed-to-satisfy systems, this solution can also provide security.
Note: The Australian Window Association “Window Safety Tips” recommends:
‘If you have young children in your home and are considering installing security screens be aware that the security screen may prevent escape in case of fire. Ensure at least one window in the room has a release mechanism on the security screen.’
