Yes, open-cell spray foam is air-impermeable when installed at the proper thickness, typically between 3.0 and 5.5 inches depending on the specific product. It meets the International Residential Code definition of an air-impermeable insulation material, which requires an air permeance of 0.02 L/s-m² or less at 75 Pa pressure differential when tested per ASTM E2178 […]
Most homeowners in Charlton fail to account for local climate factors when installing open-cell foam. The biggest mistakes involve insufficient thickness to control moisture and applying the material to dirty or damp surfaces. These errors lead to poor air sealing, structural rot, and wasted money.
