What Is a Fire Collar?
A fire collar is a critical passive fire protection device used to seal plastic pipe penetrations through fire-rated walls and floors.
When exposed to heat, the intumescent material inside the collar expands and crushes the pipe, sealing the opening to prevent fire and smoke spread.
Why Fire Collars Are Required in Australia
Under the National Construction Code (NCC), all penetrations through fire-rated elements must maintain the fire resistance level (FRL).
- Prevents fire spreading between compartments
- Required for compliance inspections
- Mandatory for most multi-residential and commercial builds
