energy in the form of heat‚ to be transferred within the material‚ without any movement of the material itself. An easy way to understand this concept is through a simple demonstration. An insulator is a material that does not allow a transfer of electricity or energy. Materials that are poor thermal conductors can also be described as being good thermal insulators. Well-insulated buildings need less energy for heating than buildings that have no insulation. Two building materials that are being used
