SPRAY FOAM INSULATION
Spray polyurethane foam (SPF) is better than any other type of insulation at reducing air leakage. A closed-cell spray foam provides a higher R-value per inch (6.5) than less expensive insulation types like cellulose and fiberglass (3.5 to 3.7).
Most spray polyurethane foam is called "two-component" foam. Two ingredients—conventionally called "A" and "B" components—are mixed on site usually installed by professionals. This is a very sensitive product to temperature. If not stored and applied in the right temperature environments, you may not achieve the desired results.

OPEN CELL SPRAY FOAM
Although open-cell foam costs less than closed-cell foam, it has a lower R-value per inch, so a thicker layer is required. If the framing members are deep enough to accommodate your required R-value, open-cell foam may end up costing less.
CLOSED CELL SPRAY FOAM
Closed-cell foam isn't cheap, but it provides a much higher R-value per inch than open-cell foam. Because of its density and glue-like tenacity, it also adds structural strength to a wall, ceiling, or roof assembly.
