Open Cell Foam is foam in which the cells that make up the product are not as tightly interlaced as Closed Cell Foam. This makes the foam better for insulation than fiberglass, but not as insulated as Closed Cell. For personal projects and residences Open Cell foam insulation is the most common choice for consumers.
Closed Cell is a more insulated variety of foam compared to Open Cell foam. The cells that make up the insulation are tightly packed together and entrap gas within the cells. That leads to the foam expanding more thoroughly throughout the insulated object and providing greater insulation protection. Closed Cell foam is denser than Open Cell foam, which makes it heavier and more is needed to insulate an area.
