Which term describes a material that resists the flow of heat, reducing heat transfer between objects?

Explanation:
Materials that resist heat flow have low thermal conductivity and are called insulators. An insulator slows down heat transfer between objects by hindering conduction, convection, and even some radiant transfer, helping keep temperatures steadier. This is why things like fiberglass, wood, or plastic are used to insulate spaces or objects. The other terms don’t fit as well: a conductor passes heat easily, so it doesn’t block transfer; a transmitter isn’t a standard term for heat flow; a reflector mainly deals with bouncing radiant heat and isn’t a general description of resisting heat transfer.
