ASMACO PU Foam Fire Retardant B1 (750 ml) is an advanced, moisture curing polyurethane foam developed for fire blocking and insulation applications in residential and commercial construction. Engineered to slow flame spread and self extinguish, this foam helps improve fire safety when sealing joints, cavities, and service penetrations.
The foam expands to form a durable, airtight, and water resistant seal, effectively limiting the passage of fire, smoke, and air between compartments. It bonds strongly to a wide variety of building materials including wood, drywall, metal, masonry, glass, and most plastics, making it a reliable solution for fire stopping concealed spaces. Its aerosol format ensures easy application with consistent results, even in hard-to-reach areas.
