Teflon insulation, which is a lot closer to being fireproof than the
cheaper plastics. "Plenum" cable is for installation in areas used for
air circulation -- e.g., the above-ceiling-tile space in many buildings --
where the fire-safety people are very touchy about fire/smoke hazards.
In general, you use plenum cable if fire-safety codes say you must, and
regular cable otherwise. For home use, stick to regular.
