a substance that does not readily transmit electricity, light, or heat.

nonconductor

/non·con·duc·tor/ (non″kon-duk´ter) a substance that does not readily transmit electricity, light, or heat.

nonconductor

(non?con-duk'tor) [L. non, not, + con, with, + ductor, a leader]
Any substance that does not transmit heat, sound, or electricity or that conducts it with difficulty. Strictly speaking, there is no perfect nonconductor. On the application of a sufficiently high voltage, current may be caused to flow through materials usually spoken of as nonconductors.
