The advantages of the closed-cell foam compared to open-cell foam include its strength, higher R-value, and greater resistance to the leakage of air or water vapor. The disadvantage of the closed-cell foam is that it is more dense, requiring more material, and therefore, more expense.
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.
