Insulation materials like foam, cellulose, fiberglass and foils are interposed between walls to keep sound or thermal energy from transporting from one area of a building to another.
Insulation is a material or system used to reduce the transfer of heat, sound, or electricity between different environments. In construction, insulation is applied to walls, roofs, floors, and other building components to enhance energy efficiency, maintain comfortable indoor temperatures, and reduce noise. Common insulation materials include fiberglass, foam board, and spray foam.
Material used to reduce heat transfer and improve energy efficiency.
