Bradford Ventilation Maestro BAL 300mm

The Bradford Ventilation Maestro BAL 300mm is a roof vent built for homes in bushfire-prone areas. It is designed to meet Bushfire Attack Level requirements while still moving a steady flow of air out of the roof space, which makes it a practical choice on a BAL-rated build where a standard vent would not be allowed. The 300mm diameter gives it the capacity to ventilate a medium to large roof cavity, and the construction is made to stand up to Australian weather.

How It Works

The Maestro is a static vent, which means it lets warm air rise out of the roof space through the unit without any moving parts or power draw. The BAL design keeps the airflow path open while the ember screen stops firebrands getting into the roof cavity. That combination is what lets the roof space stay ventilated in an area where ember attack is a real risk during a bushfire.

Applications

• Roof ventilation on homes in bushfire-prone areas
• Venting medium to large roof cavities
• New builds and retrofits where a BAL-rated vent is specified
• Reducing condensation and heat build-up in the roof space

What You Need To Complete The Job

Where the vent connects to a duct run, use flexible foil ducting to carry the airflow to the vent position. For a lower-profile alternative on non-bushfire builds, consider the Low Profile Roof Vent. Browse the Roof Ventilation range for the full selection.

Frequently Asked Questions

What does the BAL rating mean for this vent?

The vent is designed to meet Bushfire Attack Level requirements, which in practice means it includes ember protection so firebrands cannot get into the roof space through the vent. That is what makes it suitable for builds in bushfire-prone areas where a standard vent would not be compliant.

Does it need power to work?

No. It is a static roof vent that works by natural airflow. Warm air rises out of the roof cavity through the vent, so there are no fans, no wiring and nothing to maintain.

What size roof space does it suit?

The 300mm diameter gives it the airflow capacity for a medium to large roof cavity. For a smaller roof space, a smaller vent or a different unit may be a better match.

What roofing profiles does it fit?

It is compatible with a wide range of roofing profiles and materials. Check the vent against your roof profile before ordering to confirm the fit.

Can the Maestro be retrofitted to an existing roof?

Yes. The vent mounts to the roof at a high point where warm air collects, and it can be fitted during a re-roof or added to an existing roof. Because it is a static unit, there is no wiring to run, which keeps a retrofit to the roof work itself.
