DuPont^™ Enerfoam^™ Professional Foam Sealant is a water-resistant polyurethane foam that adheres to most building substrates. Ideal for sealing all manner of cracks and voids, it also can work as a fireblock. 

• DuPont^™ Enerfoam^™ is great for adhering insulated concrete forms, architectural foam and drywall, as well as for sealing cracks and voids such as pipe penetrations. 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 repels and deflects water, reducing the potential for moisture damage to wood substrates. Plus, the one-component, minimally expanding, flexible polyurethane foam is quick and easy to use.
