Fiberseal Packing Wools


Fiberseal packing wool is an asbestos-free, non-combustible bulk insulation material formed with mineral oil as a binder. The bulk wool adsorbs less than 2 percent moisture and will not corrode steel or aluminium.

  • Easily packable into grooves, slots and other hard-to-reach openings, as well as electrical conduit breaks
