The Soudal Gap Filling Expanding Foam is a hand-held polyurethane expanding foam filler formulated for gap filling applications with high three-dimensional expansion. It is a one-component product that cures rapidly and offers thermal and acoustic insulation properties. The foam adheres without primer to most construction materials.
This expanding foam has a volume yield of approximately 23 litres per 750ml can (FEICA TM1003 standard). Its acoustic insulation rating is 58 dB according to ISO 717-1, and it has a thermal conductivity of 37 mW/mK as per DIN 52612. The product is intended for use within an application temperature range of +5°C to +30°C. Typical applications include filling gaps such as pipe penetrations, insulation, roofing materials, and general construction gaps.
Key Features
- Polyurethane expanding foam filler with high 3D expansion
- Volume yield: 23 litres per 750ml can (FEICA TM1003)
- Acoustic insulation rating: 58 dB (ISO 717-1)
- Thermal conductivity: 37 mW/mK (DIN 52612)
- Application temperature range: +5°C to +30°C
- Primerless adhesion on most construction materials
- Rapid curing, one-component system
Fitment & What to Check
- Ensure surfaces are clean, free from grease and dust prior to application
- Moisten surfaces with water before applying foam to improve curing and cell structure
- Fill cavities only up to 50% as foam will expand after application
- Shake the aerosol can for at least 20 seconds before and during use to maintain consistency
- For multi-layer application, moisten surfaces again between layers
Common Ordering Mistakes
- Not verifying surface compatibility for primerless adhesion
- Ordering insufficient quantity without considering foam expansion rate
- Omitting surface preparation such as cleaning and moistening which affects adhesion and curing
- Using the foam outside the recommended temperature range of +5°C to +30°C
