Spray Foam is categorized into two types, open-cell or closed-cell. Open cell is lightweight foam that is flexible, and an excellent air barrier. Open cell foams most commonly range from .5 lb to .7lb densities. Closed cell foam is higher density foam, and a moisture barrier.
Open cell spray foam is not a moisture vapor barrier, and will allow moisture to pass. So, if youâre considering spraying foam to the roof deck of your new or existing home, you want open cell. If thereâs a roof leak, water will pass through the foam, and you will quickly be able to find your problem.
