Science glossary film: Insulator

Material that conducts heat or electricity very poorly, and so can be used to provide some measure of protection. Thermal insulation in housing helps to reduce heat loss. Electrical insulation on mains cabling in houses, typically made of plastic or rubber, prevents short circuits and the risk of electric shocks.
