Sika Boom Expanding Foam (750ml)

 Sika Boom Expanding Foam is a one-component, polyurethane-based, fast-curing foam designed for sealing, filling, insulating, and bonding applications in construction and renovation. It expands rapidly upon dispensing to fill cavities, gaps, and voids, providing excellent thermal and acoustic insulation. The foam adheres well to most common building materials such as wood, concrete, metal, and plastics. It is moisture-curing and offers good resistance to aging, shrinking, and water. Â
