We are doing some Audio/ Video and CATV wiring in a 100+ year old church that has a wood and steel structure. All of the floors are wood; it's a six story structure. Most of all the electrical wire is the old fabric covered stuff, and the rest is all PVC. My question does all new wiring have to be plenum cable? None of it will actually be in an air plenum.
