Quick Answer
Internal fire doors are certified fire-rated door systems installed within buildings to contain fire and smoke for 60–120 minutes, protect escape routes, and ensure compliance with NCC and AS 1905.1.
What is an Internal Fire Door?
An internal fire door is a complete fire-rated door system (including door leaf, frame, seals, and hardware) designed for installation within a building.
These doors are used to compartmentalise fire, helping prevent the spread of flames and smoke between rooms, corridors, and critical areas.
Where Are Internal Fire Doors Used?
Internal fire doors are commonly installed in:
- Offices and commercial buildings
- Warehouses and industrial facilities
- Corridors and stairwells
- Modular and portable buildings
They are essential because they:
- Contain fire within specific areas
- Protect evacuation pathways
- Support safe building design
- Help meet Australian compliance requirements
At Larnec, internal fire doors are engineered for reliable performance in high-use environments.
Fire Door Compliance in Australia
To be compliant in Australia, internal 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
Internal fire doors are critical for compartmentation, a key requirement in building fire safety design.

When selecting an internal fire door, ensure it includes:
- Fire-rated door leaf and frame

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