Soudal Universal Gap Fill Expanding Foam 

Soudal Expanding Foam, a professional-grade, one-component polyurethane (PU) foam engineered for reliable sealing, filling, and insulating across a wide range of construction and DIY applications. Designed for efficiency and precision, this expanding foam delivers outstanding performance for both trade professionals and home users.

Product Features/Specifications:
  • One-component, self-expanding polyurethane foam
  • Moisture-cured for fast and effective setting
  • Expands up to 35–40 times initial volume
  • High thermal and acoustic insulation properties
  • Strong adhesion to wood, concrete, stone, and metal
  • Compatible with hand-held canisters or spray guns
  • Paintable and cuttable once fully cured

Product Benefits:
Soudal Expanding Foam offers exceptional sealing capability, ensuring airtight and watertight finishes that improve energy efficiency in buildings. Its high expansion rate allows users to cover large gaps with minimal material, reducing waste and cost. The foam’s superior insulation properties help regulate indoor temperatures and minimise noise transmission, making it ideal for both residential and commercial environments.

The innovative Genius Gun system enhances usability, enabling precise, one-handed application and allowing the product to be reused for up to six weeks—perfect for projects that require intermittent use. Additionally, specialty variants such as fire-rated foam provide enhanced safety by resisting fire for up to four hours, while low-expansion options protect delicate structures like window and door frames.

Applications and Versatility:
Soudal Expanding Foam is highly versatile and suitable for:
  • Sealing gaps around window and door frames
  • Filling pipe penetrations and service voids
  • Insulating cavity walls and roofing spaces
  • Fixing and stabilising building elements
  • General gap filling in interior and exterior environments
Its adaptability makes it a go-to solution for construction, renovation, and maintenance tasks.

Features & Benefits List:
  • High Expansion Rate - Maximises coverage with minimal product
  • Excellent Adhesion - Bonds securely to most building materials
  • Thermal & Acoustic Insulation -  Enhances comfort and efficiency
  • Genius Gun Technology - Precision control and reusability
  • Versatile Product Range - Options for fire resistance, low expansion, and bonding
  • Easy Finishing - Can be trimmed and painted after curing

Technical Specifications:
  • Product Type: One-component polyurethane (PU) foam
  • Curing Method: Moisture curing
  • Expansion Rate: Up to 35–40x initial volume
  • Application Method: Aerosol canister or spray gun
  • Adhesion Surfaces: Wood, concrete, stone, metal
  • Non-Adhesion Surfaces: PTFE, PE, PP
  • Post-Cure Finish: cutting and painting
  • Cleaning (Fresh): Soudal Gun & Foam Cleaner or acetone
  • Removal (Cured): Mechanical only

Important Usage Tips:
  • Lightly moisten surfaces before application to improve curing performance
  • Fill cavities only one-third full to allow for expansion
  • Clean uncured foam immediately; cured foam requires mechanical removal
  • Soudal Expanding Foam delivers dependable, high-quality results—making it an essential addition to any professional toolkit or DIY project.
