STICK2 B1 Fire Rated Expanding Gun Foam Sealant is a high-performance, one-component polyurethane expanding foam designed for professional mounting, sealing and insulation applications. The foam cures by reacting with air moisture and delivers strong, reliable adhesion to most common construction materials.

This gun-grade B1 fire rated foam provides excellent heat insulation, sound absorption and long-term ageing resistance. It is also resistant to mould growth and fungal attack, making it suitable for demanding internal and external construction environments.

The foam adheres effectively to brick, concrete, plaster, wood, glass, metals, foamed polystyrene, rigid PVC and rigid PUR foams. It does not adhere to polyethylene, silicone or Teflon.

Each can delivers a yield of approximately 0.044m³, providing efficient coverage for professional use. Supplied in a 750ml aerosol and includes a free pair of protective gloves.
