As Fire Season is in full swing we are also in full swing installing a range of Fire Shutters. The fire shutters are group into the same classifications as BAL ratings.
BAL (Bushfire Attack Level) ratings are used in Australia to classify the level of risk a property may face in the event of a bushfire. The BAL rating is based on factors such as the type of vegetation, the slope of the land, and the distance of the property from potential fire threats. Different types of fire roller shutters may be recommended based on the BAL rating. Here are general guidelines:
- BAL 29 (Bushfire Attack Level 29):
- For BAL 29, roller shutters with ember attack resistance are typically recommended. These shutters are designed to withstand embers and radiant heat associated with lower levels of bushfire risk. These roller shutters have a thinner wall, foam filled slats. Made from Aluminum
- BAL 40 (Bushfire Attack Level 40):
- For BAL 40, shutters with increased resistance to radiant heat and direct flame contact are necessary. These shutters are built to provide more protection in areas with a higher risk of bushfires.These roller shutters have a thicker wall profile and are what we call extruded they are available in both hollow and foam filled profile. Made from Aluminum
- BAL-FZ (Bushfire Attack Level – Flame Zone):
- In Flame Zone areas, which are at the highest risk of bushfires, roller shutters need to be highly resistant to direct flame contact and extreme heat. They must comply with strict building codes and standards for such high-risk zones. Made from stainless steel and headbox/side rails may be Aluminum
It’s important to note that building regulations and standards can vary between different regions and may be subject to updates. Therefore, it is crucial to consult with local authorities or a building professional in your specific area to determine the appropriate type of fire roller shutters that meet the current building codes and standards for your BAL rating. Additionally, manufacturers of roller shutters often provide products that comply with specific BAL ratings, so it’s advisable to choose products from reputable suppliers with a track record of meeting the required standards.
This project was in Suburb of Hobart called Ferntree on Mt Wellington, all shutters are motorised with 12v system except the larger entrance doorway, which is motorised with 240v motor with manual override control. This shutter cover doors and two windows.
We also installed two Invisi-Guard 316 Stainless security doors rated at BAL-40
