Performance & Testing
Bushfire Testing to AS1530.8.1
Bushfires in Queensland are sadly a common occurrence during summer months due to Australia’s hot and dry climate. Bushfires can be tragic events. The Invisi-Gard BAL40 screen range has been designed to withstand temperatures of up to 40 kW without failure to the EGP retention system. Protection from ember attack and burning debris preventing internal ignition to the building prevents possible loss of homes from the start.
- Invisi-Gard is bushfire rated and protects your property from floating embers and reduces heat intensity of radiant heat flux.
- Invisi-Gard complies with the mesh aperture for screening of openable parts of windows up to BAL-FZ conditions.
- The Invisi-Gard BAL40 screen range successfully exceeded system test requirements outlined in AS1530.8.1 while remaining in operation after the test.
| Bushfire Attack Level (BAL) | Description of predicted bushfire attack and levels of exposure |
|---|---|
| BAL - LOW | There is insufficient risk to warrant specific construction requirements |
| BAL - 12.5 | Ember attack |
| BAL - 19 | Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux between 12.5 and 19 kW/m² |
| BAL - 29 | Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux between 19 and 29 kW/m² |
| BAL - 40 | Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux with the increased likelihood of exposure to flames |
| BAL - FZ | Direct exposure to flames from fire front in addition to heat flux and ember attack |
