Promat fire resistant collars are manufactured using intumescent technology. These collars are designed to maintain the integrity of the fire resistant element through which plastic pipes, combustible insulation, cables or fibre optic facilities pass. Fire collars are suitable for installation in the various types of floors, walls and ceilings in which they have been
tested.

In the event of fire, the plastic pipe will start to deform. In the case of uPVC pipes this occurs at a temperature of approximately 70°C. Once the pipe starts to deform, the intumescent material in the Promat fire collar expands, closing off the plastic pipe or combustible insulation, and thus forming an insulating barrier.

This intumescent compound continues to expand throughout the fire and forms a char which prevents flame and hot gases passing into adjacent compartments.

Compliant installations for the fire protection of service penetrations is not as straight forward as many would believe.  There are many traps that can catch out an unwary installer who may believe that they are doing the right thing, but in fact are not meeting all the requirements. The paragraphs below will attempt to help an installer navigate their way to a compliant installation for a fire collar system.

Fire protection of service penetrations through fire rated elements, is a requirement of the building code. Clause C3.15 in Vol 1 states that "the service, building element and any protection method at the penetration are identical with a prototype assembly of the service, building element and protection method which has been tested in accordance with AS4072.1 and AS1530.4 and has achieved the required Fire Resistance Level (FRL)..."

So to comply with the requirements of this clause it is not just about the collar itself. All the components listed have to be part of that tested system.

The parts of the system include:

  •  The size and type of plastic pipe used.(service)
  •  The type, size, construction and Fire Resistance Level (FRL) of building substrate that the pipe passes through and that the collar is installed on (building element)
  •  The fire collar that has been installed (protection method)
  •  The orientation of the pipe and collar (protection method)
  •  The fixing method used to apply the collar to the substrate.(protection method)

As an example, a test for a 100mm uPVC pipe in a two hour fire rated plasterboard wall (2 x 16mm each side of 64mm stud, total wall thickness of 128mm) can only be applied to an installation that uses the same wall, pipe size and collar. If the wall itself is thinner, or of a different material and the pipe is a different size or wall thickness then it will need a different approval. 

As you can see a complaint installation is not as straight forward as just installing a fire collar on a pipe. However Promat Australia have tested a wide variety of the commonly used combinations of pipe, substrate and protection methods that an installer would come across on a day to day basis. While we have a large variety of tested combinations it should be understood that their will not be a tested system for every eventuality that may occur on site. It should also be noted that if a new pipe or wall type come on the market, existing approvals may not necessarily be able to be applied to them.

If you are not sure that the combination that you are facing on site is approved, then contact your local Promat office for further advice.
