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.

• 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 penetrations and cavities, supporting effective compartmentalization.
• Thermal & Environmental Resistance: Designed for high-temperature environments and remains stable after curing.
• Strong Adhesion: Bonds well to most building substrates, including masonry, wood, and metal.
• Moisture & Mold Resistance: Once cured, the foam is waterproof, mold-proof, and suitable for painting.
• CFC and HCFC free formula: Free from CFCs and HCFCs, supporting safer indoor use.
• High Yield Efficiency: Economical consumption due to precise, controlled application.

• Surface Preparation: Surfaces should be clean, dry, and free of dust, grease, and rust. Lightly misting the surface with water helps adhesion and curing.
• Optimal Conditions: Apply at ambient and surface temperatures between +32°F (0°C) and +112°F (44°C). If the can is too cold or hot, bring it to a stable temperature. Optimal can temperature is +68°F (20°C).
• Installation Method: Shake well, attach to a spray foam gun, and apply with the can valve facing downward. Fill vertical gaps bottom to top and do not overfill, the foam increases in volume.
• Curing & Protection: Protect cured foam from UV exposure by painting or covering.
• Safety Precautions: Contains Diphenylmethane-4,4’-Diisocyanate (MDI). Use gloves, protective clothing, and apply only in well-ventilated areas. Pressurized container, keep away from heat and ignition sources.
