Bond It Breeze Block Airtight PU Foam 750ML – High-Performance Airtight Expanding Foam for Construction

Bond It Breeze Block Airtight PU Foam is a premium-grade, multi-purpose gun-applied polyurethane foam specifically formulated for airtight gap filling in general construction applications. Ideal for joints subject to movement, this foam delivers superior air sealing, reducing heat loss and enhancing energy efficiency in residential, commercial, and industrial buildings.

Key Features & Benefit

  • Exceptional Airtight Seal
    Delivers <0.1m³ / [h·m(daPa)²/³] air permeability (EN 12114:2000), ensuring top-tier airtightness.
  • Superior Thermal & Acoustic Insulation
    Offers high thermal resistance and soundproofing of up to 63dB, helping to cut energy costs and noise pollution.
  • Low Expansion, No Deformation
    Near-zero curing pressure with low post-expansion prevents distortion of surrounding building materials.
  • Sub-Zero Performance
    Formulated for cold climates—usable at temperatures as low as -5°C.
  • Non-Shrinking & Durable
    Retains shape after curing for long-lasting gap sealing.
  • Reliable Bonding Power
    Strong adhesion to wood, concrete, block, stone, plaster, metal, PVC, and polystyrene.
  • Fire Classification: B2 Rated
    Reaction to fire: Class B2 (DIN 4102-1).

Common Applications

  • Installation of window and door frames, including entrance doors
  • Filling and insulating gaps, cracks, and penetrations
  • Sealing and bonding of thermal and acoustic insulation boards
  • Connecting and sealing construction joints
  • Minimizing thermal bridging for improved energy performance

Surface Preparation Guidelines

  • Ensure surfaces are firm, clean, dry, and free of dust, grease, or contaminants.
  • Moisten substrates with water to enhance adhesion.
  • Shake the can thoroughly (at least 20 times) before use and during application to maintain ideal pressure and consistency.
  • Always keep PU Foam Cleaner nearby for quick cleanup.
  • Protect adjacent areas using masking materials like paper or plastic film.

Important Limitations

  • Not suitable for fire-rated installations such as fire doors.
  • Cured foam is UV-sensitive – must be protected with paint, sealant, or other opaque coatings.
  • Does not adhere to polyethylene, Teflon®, siliconised, or waxy surfaces.
  • Secure lightweight components before application to prevent misalignment due to foam expansion.
