Fire-Retardant PU Foam for Professional Sealing and Insulating

Soudal Trade B2 Expanding Foam Gun Grade is a one-component, self-expanding polyurethane foam specially formulated to meet B2 fire classification. It is designed for application with a foam gun, offering superior control and precision. Ideal for sealing, filling, and insulating gaps, joints, and cavities in construction and installation projects where fire retardancy is important.

Key Features & Benefits

• Fire Retardant: Complies with DIN 4102 B2 classification for fire resistance in building materials.
• Gun Grade Precision: Applied with a foam gun for clean, accurate dispensing and minimal waste.
• High Yield: Expands to fill large gaps and voids with excellent volume efficiency.
• Thermal & Acoustic Insulation: Reduces sound transmission and heat loss through joints and cavities.
• Strong Adhesion: Bonds to most construction materials including concrete, brick, wood, metal, and plastics (except PE, PP, PTFE).
