Soudal Soudafoam Gap Fill High Expansion 12oz Aerosol Can, Straw Foam - 12 Pcs

Soudal Soudafoam Gap Fill High Expansion (SKU 130465) is a professional-grade one-component polyurethane foam designed for heavy-duty sealing, insulating, and cavity filling. Packaged as a convenient 12 oz aerosol can available in a bulk case of 12 pieces, this straw foam system features a moisture curing formula engineered to deliver high volumetric expansion for sealing large gaps, voids, and structural joints.

Delivering high-performance thermal insulation and acoustic insulation for soundproofing, this polyurethane sealant provides excellent adhesion across almost all substrates, including concrete, masonry, wood, and metal. It is environmentally conscious and CFC-propellant free, offering long-term stability with no shrinkage after full cure. The cured foam features a distinctive champagne colour with permanent colour stability, is mildew resistant, and offers a paintable surface once fully set for seamless finishing.

Optimized for diverse construction and mechanical trades, it is ideal for roof construction, cooling systems, and air-conditioning installation projects where thermal integrity and airtight sealing are critical.

• High-Expansion Gap Filling:
  

  The foam expands significantly to fill cavities, gaps and openings, making it suitable for larger spaces that need filling and sealing.

  
  
  
• Thermal Insulation:
  

  Provides thermal insulation for gaps and cavities, helping improve insulation around construction components and installation areas.

  
  
  
• Acoustic Insulation:
  

  Provides acoustic insulation that can help reduce sound transmission through gaps and openings in construction areas.

  
  
  
• Excellent Adhesion:
  

  Designed to provide excellent adhesion to almost all common construction substrates, supporting a range of sealing and filling applications.

  
  
  
• Moisture-Curing Polyurethane Formula:
  

  The one-component polyurethane formula cures in the presence of moisture, making it suitable for construction, sealing and insulation applications.

  
  
  
• No-Shrinkage Performance:
  

  The foam is designed not to shrink after curing, helping maintain the filled volume once cavities and gaps have been filled.

  
  
  
• 12 oz Straw Can:
  

  The 12 oz aerosol can provides a convenient dispensing format without requiring a separate foam gun.

  
  
  
• HVAC and Air-Conditioning Applications:
  

  Can be used for installing HVAC units and creating insulation around cooling and air-conditioning installations.

  
  
  
• Large Opening and Cavity Sealing:
  

  Suitable for filling cavities and sealing large openings and gaps where expanding foam is needed for insulation and sealing.

  
  
  
• Paintable After Curing:
  

  The cured foam can be painted over, giving you flexibility when finishing treated construction surfaces.
