An insulator.
An insulator for heat and (less so) for electricity. A conductor for sound and vibration.
electric circuit
Fiberglass is a good insulator of heat. It is often used in homes and buildings to help regulate temperature by reducing the transfer of heat between different spaces.
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator

a insulator of electricity is a material that insulates, especialy a nonconuctor of sound,heat,or electricity.
insulator
An insulator is an object that electricity, heat or sound cannot pass through. It is the opposite to conductor.
An insulator.
an insulator- to prevent or reduce the transfer of electricity,heat,or sound by surrounding or lining with a non-conducting material.
An insulator for heat and (less so) for electricity. A conductor for sound and vibration.

Wood is a gd insulator as it is a poor conductor. whereas metal is a gd conductor but poor insulator.
a potato is not an heat insulator because it's skin,but if you take the skin off it will be a heat insulator
An insulator is a poor conductor of energy. For example; Rubber is a poor conductor of electricity Rock is a poor conductor of heat A sponge is a poor conductor of sound.
