Insulation systems are materials and methods used to reduce the transfer of heat, sound, or electricity between different environments. They are commonly found in buildings, where they help maintain comfortable indoor temperatures by minimizing heat loss in winter and heat gain in summer. Common insulation materials include fiberglass, foam, and cellulose, each with unique properties and applications. In addition to thermal insulation, some systems also provide soundproofing and electrical insulation. Effective insulation systems contribute to energy efficiency, reducing heating and cooling costs, and enhancing overall comfort. Proper installation and maintenance are essential for maximizing their performance and longevity.
