PRODUCTS - Firestop Collars

PFC Corofil Fire Stop Collars provide a simple and effective method of firestopping plastic pipework where it passes through compartment walls and floors.
Tested to BS476 Part 20, Fire Stop Collars will provide up to 4 hours' fire protection.
> Simple to install
> Water resistant
> Maintenance Free
> Available to suit pipe sizes ranging from 55 to 355mm O.D.
PFC Corofil Firestop Collars consist of a powder coated steel sleeve containing a flexible graphite based intumescent liner manufactured to suit the pipework to be firestopped. Integral toggles are opened up and the collar is simply fitted around the plastic pipe. The toggles are closed and the collar is pushed flush to the surface of the wall or underside of floor. The collar is then securely fastened to the structure by means of fire resistant fixings threaded through fixing tabs. Any gaps of up to 25mm wide around the pipework should be filled with PFC Corofil Acoustic Intumescent Sealant. For gaps greater than 25mm PFC Corofil Firestop Compound can be used.
Under fire conditions the intumescent material swells filling the void left by the burnt out plastic.
