Foam insulation is a type of insulation material made from polyurethane or polystyrene, designed to reduce heat transfer in buildings. It is commonly used in walls, roofs, and floors to improve energy efficiency and maintain comfortable indoor temperatures. Foam insulation can be applied as a spray, board, or in rigid panels, providing a seamless barrier against air leaks. One of the key benefits of foam insulation is its high R-value, which measures thermal resistance. This means it can effectively keep homes warmer in winter and cooler in summer, leading to lower energy bills. Additionally, foam insulation can help reduce noise transmission between rooms.
