NU-FOAM 12OZ 4293-04

Nu-Foam 12oz expanding insulating sealant provides superior air sealing and thermal insulation in a single application. This polyurethane foam expands to fill gaps, cracks, and voids around windows, doors, pipes, and penetrations, creating an airtight barrier that reduces energy loss and lowers heating and cooling costs. The closed-cell formula offers excellent insulating properties while resisting moisture infiltration and air leakage. Easy to apply with a standard applicator gun, it cures to a rigid foam that can be trimmed and painted for a finished appearance. Ideal for new construction, renovations, and weatherization projects where energy efficiency and air sealing are priorities. One 12oz can covers multiple applications, making it a cost-effective solution for professional contractors and builders.
