Thermal insulation materials are substances used to reduce the transfer of heat between objects or environments. They help maintain desired temperatures in buildings, appliances, and other structures by slowing down the flow of heat. Common types of thermal insulation include fiberglass, foam, and cellulose, each with unique properties and applications. These materials are essential for energy efficiency, as they minimize heating and cooling costs. By using thermal insulation, homeowners and businesses can create more comfortable living and working spaces while reducing their environmental impact. Proper installation and selection of insulation materials can significantly enhance overall energy performance.
