Full passive fire plumbing technical manual.
The Allproof Low Cast In Passive Fire Collars have been designed and tested on a wide range of plastic plumbing pipes through concrete floors that are poured on site. The low cast-in collar is installed in a similar manner to the standard cast-in collar, the design of these low cast in fire collars allows the installer to simply fix the base of the cast in fire collar to the formwork, the pipe penetration is then installed through the formwork and acts as the riser to the required height during the concrete pour. The pipe should be capped to prevent concrete entering the pipework during construction. This process eliminates the need for core drilling of penetrations after the floor is poured and retro fitting a fire collar or wrap. This method allows structural steel to be installed around the penetration.
The low cast in fire collars consist of intumescent strip(s) encased in a recycled PPE plastic casing with fixing base. In the event of a fire, the intumescent material expands casing as the penetration service melts or deforms. The cast in fire collars have a steel ring at the base, enabling fast activation of the intumescent, forming a stable fire-resistant seal, maintaining both fire integrity and insulation.
The Allproof low cast in profile collars have been tested at accredited fire laboratories in accordance AS1530.4 and AS4072.1. The Collars have been tested and designed to for both stack and floor waste penetrations.
