insulators
Conductivity prevention materials
Insulators are materials that resist the flow of heat, electricity, or sound.
Rubber and glass insulate against electrical current; foam and fiberglass insulate against heat loss.
The term extends to devices made from these materials: the ceramic or glass insulators on power lines prevent electricity from escaping into the poles.
Figuratively, wealth can be an insulator against hardship.
