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.
The most common uses for open-cell foam are thermal insulation for vaulted ceilings and attics (barrier sometimes required), and for sound-proofing under floors and walls. (5-6 inches is required, compared to 2 inches). Closed-cell foam has varying degrees of hardness and rigidity, depending on its density.s the most effective type of insulation, closed-cell Sprayed Polyurethane FOAM (SPF) is a solid, rigid, waterproof, and seamless plastic after it cures (in only a few seconds). It is impervious to liquid or gas penetration.
