Cable trays and cables while not as highly conductive as metal pipes will still transfer heat to the unexposed side of a fire resisting element. In these cases the penetrating element must be protected so as to not transfer this heat and possibly contribute to fire spread. The advantage of the SupaWrap product is that the extension of the wrap is only for 300mm* (depending on wall thickness) from the face of the wall as opposed to other solutions that can be as long as 800mm.
