Our unique fire sleeves are ETA approved for use on uninsulated plastic pipe. Not only do they provide a certified fire resistance of EL120, they also provide a smoke and noise barrier. Fire sleeves can be useful where significant pipe movement is expected as, unlike most collars, they still allow the pipe to move. This can be commonplace on tall buildings. You also only need one sleeve per penetration so they can be installed quickly and easily without additional fixings.
