Open-cell foams are a softer and more flexible material because cells are created open.


One of the biggest benefits of open-cell foam is that it expands significantly after it has been applied. It is, therefore, an ideal material to reach into all the nooks and crannies and to ensure an effective air seal – a key to energy efficient homes. This air sealing process is also an important contributor to the soundproofing benefits delivered by open-cell foam.
