Q

A type of enclosed space in a building (such as the one between a dropped ceiling and the structural ceiling) used for air handling is commonly referred to as a plenum space. A special type of cabling with fire-retardant jacket placed inside that space is known as a plenum-rated cabling. Materials from which the plenum-rated cable’s cover is made include low-smoke Polyvinyl Chloride (PVC) and Fluorinated Ethylene Polymer (FEP).
