âyeq (#)

Fr.: isolant   

1) A material or an object that does not easily allow heat, electricity, light, or sound to pass through it.
2) Electricity: A material, such as glass or porcelain, that opposes a very high resistance to the passage of an electric current so that the flow of current through it is negligible; a nonconductor.
3) One who, or that which, insulates.

Agent noun from → insulate + → -or.
