Enerfoam 30oz Sealant - Fireblock Rated, Polyurethane Expanding Foam Sealant. Gaps and Cracks Filler. Water Resistant, Closed Cell, Spray Foam Insulation. Pack of 12. Applicator Gun Not Included

Fireblock: Enerfoam Professional Foam Sealant is a single-component, flexible polyurethane low-expanding, closed-cell spray foam utilized for bonding insulated concrete forms, architectural foam and drywall, and sealing gaps and openings like pipe penetrations. The foam expands just enough to create an efficient seal, maintaining flexibility as the structure moves and contracts. Insulating Foam Sealant: This product is engineered to establish a long-lasting, airtight, water-resistant adhesion to typical construction materials such as wood, brick, concrete, foam board and most plastics. Its cured foam surface repels water, which can aid in lowering the possibility of moisture harm to wooden substrates. In the United States, this foam is also classified as a fireblock, indicating it hinders the unrestricted movement of flames to different sections of the building via concealed spaces. Tested and Certified: 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
