Insulating foams are materials designed to reduce heat transfer, making them effective for energy conservation. They are commonly used in building construction, refrigeration, and packaging. These foams can be made from various substances, including polyurethane and polystyrene, and are available in different forms, such as rigid panels or spray applications. The primary function of insulating foams is to create a barrier that slows down the movement of heat, keeping spaces warm in winter and cool in summer. This helps improve energy efficiency in homes and appliances, ultimately leading to lower energy costs and a reduced environmental impact.
