FRC™ pipes are deemed non-combustible by the Building Code of Australia. FRC™ pipes that penetrate fire resistance rated walls or concrete floors, achieve fire resistance levels up to and including 4 hours.

FRC™ pipes that have a nominal I.D. of up to and including 750mm, and a pipe wall thicker than 10.8mm which penetrates concrete or masonry fire resistance rated walls or concrete floors, can achieve fire resistance level (FRL) for integrity, of up to -/240/0. When the thickness of the pipe wall is more than 20mm, the FRL for integrity and insulation is -/240/30.

With respect to insulation, fire performance depends on the wall thickness of the FRC™ pipes and the specific details of the caulking systems. However, for the same conditions of installation, the temperature rise can be expected to be less for FRC™ pipes than for ordinary unprotected metal pipes.
