Bushfire BAL Rated Ventilation

If you’re building or renovating a home in a bushfire-prone area, it’s important to ensure that your ventilation system is up to the task of protecting your home from the dangers of bushfire smoke and embers. That’s where BAL rated ventilation systems come in.

What is a BAL Rated Ventilation System?

BAL (Bushfire Attack Level) rated ventilation systems are designed to provide protection for homes located in bushfire-prone areas. These systems are tested and rated according to the level of protection they provide against bushfire smoke and embers.

BAL rating levels range from BAL-Low (for homes located in low-risk areas) to BAL-FZ (for homes located in the most extreme bushfire-prone areas).

  • BAL rated ventilation systems provide increased protection for homes located in bushfire-prone areas, helping to keep your home and family safe during a bushfire event.
  • Installing a BAL rated ventilation system helps to ensure that your home is compliant with local building codes and regulations, providing peace of mind for you and your family.
  • BAL rated ventilation systems also help to improve indoor air quality, promoting better health and comfort for your family.
  • By improving indoor air quality and reducing the need for air conditioning, BAL rated ventilation systems can help to reduce energy costs and save you money on your monthly utility bills.
  • Prevents mould and mildew
  • BAL rated ventilation systems are easy to install and require minimal maintenance, making them an ideal choice for homeowners who want a simple, effective solution for their home.
