EXCO Ltd 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 EXCO Ltd Acoustic Intumescent Sealant. For gaps greater than 25mm EXCO Ltd Fire Compound can be used.
Under fire conditions, the imtumescent material swells filling the void left by the burnt out plastic.
