Open-cell foam

Open-cell foam is a type of insulation material made from polyurethane, characterized by its interconnected, porous structure with tiny, open cavities. These open cells trap air, providing excellent sound absorption and thermal insulation by slowing heat transfer. It is lightweight, flexible, and often used in walls, ceilings, and soundproofing applications. Unlike closed-cell foam, it is more breathable and allows moisture to pass through, reducing the risk of mold or water damage. Its ease of application and effective insulation qualities make it a popular choice for residential and commercial insulation projects.
