AKFIX 840 Construction Foam B2 Fire Rated PU Foam 750ML – Straw

The AKFIX 840 Construction Foam is a B2 Fire Rated polyurethane foam designed for sealing and insulating applications where fire resistance is a critical requirement. This foam is ideal for use in construction projects where fire safety standards must be met, providing excellent adhesion, thermal insulation, and soundproofing properties.

Key Features:

1. Fire-Rated (B2):
   • B2 Fire Rated foam, making it suitable for use in areas requiring fire resistance. The foam complies with European fire classification standards and offers protection against fire propagation for a certain duration.
2. Excellent Insulation:
   • Provides thermal and acoustic insulation, helping to improve energy efficiency and reduce sound transmission between rooms.
3. Superior Adhesion:
   • Bonds effectively to a variety of surfaces including wood, metal, concrete, brick, and PVC, making it a versatile solution for sealing and insulating gaps.
4. Easy Application:
   • Equipped with a straw applicator, allowing for easy and controlled application in hard-to-reach areas, minimizing waste and mess.
5. Weather Resistant:
   • Once cured, the foam is water-resistant and can be used in both indoor and outdoor applications.
6. Quick Curing:
   • Fast-setting foam that cures in 24 hours, reducing project downtime.
7. Expands to Fill Gaps:
   • Expands to fill gaps and cracks effectively, ensuring complete coverage of cavities and openings.

Applications:

• Fire-Resistant Sealing:
  • Ideal for sealing gaps and joints in walls, ceilings, and floors, particularly in areas that require fire-rated materials, such as fire-rated doors, ventilation ducts, and electrical penetrations.
• Construction Projects:
  • Suitable for construction, renovation, and insulation projects, where both fire resistance and insulation properties are needed.
• Energy Efficiency:
  • Improves the thermal insulation of buildings, helping to reduce heating and cooling costs.
• Soundproofing:
  • Used for acoustic insulation in walls, floors, and ceilings to minimize sound transmission between rooms.

Available Size:

• 750ML (Straw applicator)

Technical Specifications:

• Type: B2 Fire Rated Polyurethane Foam

How to Use:

1. Preparation:
   • Shake the can thoroughly for about 20-30 seconds to ensure proper mixing of the components.
2. Attach the Straw Applicator:
   • Screw the straw applicator onto the can to ensure a precise and controlled foam application.
3. Surface Preparation:
   • Clean the surfaces to be foamed. Lightly dampen the surfaces for better adhesion, especially in dry conditions.
4. Application:
   • Hold the can upside down and apply the foam directly into gaps, cracks, or joints. Use the straw applicator to reach hard-to-access areas.
5. Curing:
   • Allow the foam to cure. Full curing typically takes 24 hours, but the foam may skin over in 10-15 minutes.
6. Trimming:
   • Once fully cured, excess foam can be trimmed with a utility knife for a clean finish.

Advantages:

• Fire Resistance: B2 fire rating makes it ideal for fireproofing applications.
• Fast and Efficient: Cures quickly and provides reliable insulation and sealing.
• Precise Application: The straw applicator ensures accurate and mess-free application.
• Versatile: Works on various surfaces and can be used in both indoor and outdoor environments.
• Improved Insulation: Offers both thermal and acoustic insulation, enhancing energy efficiency and reducing noise transmission.

The AKFIX 840 Construction Foam B2 Fire Rated PU Foam 750ML – Straw is an excellent choice for sealing, insulating, and fireproofing construction projects, offering fire resistance, thermal insulation, and soundproofing in one easy-to-apply solution. It’s perfect for areas requiring compliance with fire safety standards while also providing reliable performance in a variety of construction and renovation applications.
