Insulating materials are substances that reduce the transfer of heat, sound, or electricity. They are commonly used in construction, appliances, and electrical systems to improve energy efficiency and safety. Examples include fiberglass, foam, and ceramic materials, each designed for specific applications. These materials work by trapping air or creating barriers that slow down the movement of energy. In buildings, insulation helps maintain comfortable temperatures, while in electrical systems, it prevents short circuits and protects users. Proper use of insulating materials can lead to significant energy savings and enhanced performance in various applications.
