Enerfoam 30oz Sealant, Fireblock Rated, Polyurethane Expanding Foam Sealant, Gaps and Cracks Filler, Closed Cell Spray Foam Insulation, Pack of 12.

Value Kit: Contains one case (12, 30oz cans) of Enerfoam, two cans of Great Stuff Pro Foam Cleaner 12oz, and one foam gun. Fireblock: Enerfoam Professional Foam Sealant is a single-component, flexible polyurethane minimal expanding, closed-cell spray foam. It is utilized for adhering insulated concrete forms, architectural foam and drywall, and for sealing cracks and voids like pipe penetrations. The foam expands sufficiently to create a reliable seal, maintaining elasticity as the structure expands and compresses. Insulating Foam Sealant: Enerfoam is formulated to establish a durable, airtight, water-resistant bond to common building substrates such as wood, brick, concrete, foam board, and most plastics. Its foam skin repels water, which can assist in reducing the potential for moisture damage to wood substrates. In the U. S., Enerfoam is additionally recognized as a fireblock, meaning it hinders the free passage of flames to other areas of the building through concealed spaces. Tested and Approved: ASTM E84 - Standard Test Method for Surface Burning Characteristics of Building Materials. ASTM E814 - Standard Test Method for Fire Tests of Through-Penetration Fire Stops
