Insulation foam is a type of material used to reduce heat transfer, making buildings more energy-efficient. It is commonly made from materials like polyurethane or polystyrene and can be applied in various forms, such as spray foam, rigid boards, or foam sheets. This helps keep homes warm in winter and cool in summer, leading to lower energy bills. In addition to thermal insulation, foam can also provide soundproofing benefits, reducing noise between rooms. It is often used in walls, roofs, and floors, as well as in appliances and vehicles to enhance energy efficiency and comfort.
