Bushfire Attack Level (BAL) 40
Australian Online Roller Shutters
Ozroll AE401 Extruded Shutters now tested to withstand
Bushfire Attack Level (BAL) 40
Back in 2002 Ozroll had approached the CSIRO to determine the benefits of our window roller shutters when subjected to excessive heat throughout a simulated bushfire attack.
The end result was that the shutter was proven to withstand a maximum
radiant heat flux of 29kw/m2 and had still remained
operable.
This test was for the AR400 slat used in the manufacture of the Domestic Roller Shutter.
There have also been factual accounts where the Ozroll shutters have been
credited with saving homes from burning to the ground when other surrounding
properties were not so fortunate.
After the most recent fires in Victoria there were changes made to local
council regulations that required new dwellings to comply with specific
ratings, in particular within high risk areas.
With this in mind Ozroll again carried out further testing with the
CSIRO however on this occasion it was decided to test for a higher rating
using our AE401 extruded aluminium shutter which is used in the manufacture of the Security Roller Shutter.
The test was completed In November 2010 and the conclusion for this test was that the Ozroll window shutter was again proven to withstand the impact of a simulated bushfire attack, however this time with a maximum radiant heat exposure of 40kw/m2.
After 60 minutes of severe testing there was no ignition or flaming observed and we are now pleased to confirm that the
OZROLL AE401 shutter passed to the level of BAL 40.
CSIRO – Bushfire Simulation Testing on OZRoll® Window Shutters.
It is common knowledge that hot or burning embers entering the home is a major factor for the ignition of the building itself. The above test report proves conclusively that the home stands a better chance in case of bushfire if fitted with OZRoll® roller shutters.
