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 & Cleaner Included

DuPont Enerfoam Professional Foam Sealant is a one component, flexible polyurethane minimal expanding, flexible polyurethane closed cell spray foam used for adhering insulated concrete forms, architectural foam and drywall, and sealing cracks and voids such as pipe penetrations. The foam expands only enough to generate an effective seal, retaining elasticity as the structure expands and compresses. Enerfoam is designed to form a durable, airtight, water resistant bond to common building substrates such as wood, brick, concrete, foam board and most plastics. Its foam skin deflects water, which can help reduce the potential for moisture damage to wood substrates. In the U.S., Enerfoam is also recognized as a fireblock, which means it resists the free passage of flames to other areas of the building through concealed spaces. Enerfoam Professional Foam Sealant is tested to the following standard: 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. Enerfoam complies with the following code: Underwriters Laboratories, Inc. (UL) Classification, Classified as a sealant; see UL R13655 – ICC-ES ESR-1961 (US). CCMC 13074-R (CAN).
