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 foam sealant, two cans of Pro Foam Cleaner 12oz, and one foam gun. Fireblock: This professional foam sealant is a single-component, flexible polyurethane, minimal-expanding, closed-cell spray foam utilized for adhering insulated concrete forms, architectural foam and drywall, and sealing gaps and openings like pipe penetrations. The foam expands sufficiently to create an effective seal, maintaining elasticity as the structure moves. Insulating Foam Sealant: It forms a durable, airtight, water-resistant bond to common construction substrates such as wood, brick, concrete, foam board and many plastics. Its foam surface repels water, which can help minimize the potential for moisture damage to wood substrates. In the U.S., it is also recognized as a fireblock, meaning it resists the free passage of flames to other building areas 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
