X-Climate Pro Fire Block Foam – 24 oz

X-Climate Pro Fire Block Foam is a professional-grade fire block solution developed for sealing and insulating gaps, cracks, and penetrations in both interior and exterior building assemblies. This single-component polyurethane foam is designed to support effective fire blocking by limiting air movement through concealed spaces, while also improving thermal efficiency. X-Climate Pro Fire Block Foam adheres strongly to common construction materials and delivers consistent results across a wide application temperature range from 32°F to 112°F (0°C–44°C). It cures into a durable, paintable seal that resists moisture and mold, making it suitable for long-term use in residential and light commercial projects. Key Features Controlled Expansion Performance: Functions as a reliable fireblock foam that fills gaps evenly without excessive pressure on surrounding materials. Gap-filling expansion: Expands to fill 1/4" to 3" gaps. Air-Sealing Capability: Helps reduce airflow through penetration
