Which term describes a material that does not allow heat to flow easily?

Explanation:
Materials that don’t let heat flow easily are called insulators. An insulator has low thermal conductivity, so it slows or stops the transfer of heat, keeping one side cooler or warmer than the other. This is the opposite of a conductor, which readily transfers heat. The phrase “heat insulator” describes the idea, but the standard, precise term is insulator (or thermal insulator).
