Quick Answer
Double fire doors are certified fire-rated door systems designed for larger openings, consisting of two door leaves that help contain fire and smoke for 60–120 minutes while maintaining safe access and compliance with NCC and AS 1905.1.
What is a Double Fire Door?
A double fire door is a complete fire-rated door system made up of two door leaves within a single frame, including seals and fire-rated hardware.
These systems are specifically designed for wider openings where single doors are not sufficient, while still maintaining fire resistance and safe evacuation.
Where Are Double Fire Doors Used?
Double fire doors are commonly installed in:
- Warehouses and industrial facilities
- Commercial buildings and offices
- Service corridors and plant rooms
- Modular and portable buildings
They are essential because they:
- Protect larger openings from fire spread
- Maintain safe evacuation routes
- Allow movement of equipment and people
- Support compliance with Australian regulations
At Larnec, our double fire doors are engineered for Australian conditions and designed for durability in demanding environments.
Fire Door Compliance in Australia
To be compliant in Australia, double fire doors must meet strict regulatory standards, including:
- National Construction Code (NCC)
- AS 1905.1 – Fire-resistant doorsets
- AS 1530.4 – Fire resistance testing
Fire doors are assigned a Fire Resistance Level (FRL), such as:
- 60/60/60
- 120/120/120
For double doors, correct pairing, seals, and hardware are critical to maintaining compliance.
Double Fire Door Compliance Checklist
When selecting a double fire door, ensure it includes:
- Fire-rated double door leaves and frame

Common Fire Door Mistakes to Avoid
Common issues with double fire doors include:
