Description
Product Overview
The Soudal High Yield Fire Rated Foam Filler is an innovative one-component expanding polyurethane foam specifically engineered for fire-resistant applications. This advanced foam expands 35 to 40 times its initial volume, providing over 25% higher linear yield compared to standard Soudafoam FR foam. It not only meets stringent international fire standards, such as EN13501-2 class E for reaction to fire and EN1366-4 for fire resistance up to 4 hours, but also delivers exceptional thermal and acoustic insulation.
Applications
This versatile foam filler is ideal for:
- Large gap filling in passive fire protection systems
- Installing fire retardant window and door frames
- Sealing expansion joints, connection joints, and penetration seals
Its rapid curing time and strong adhesion to most construction materials—without the need for a primer—make it a go-to choice for professionals.
Key Features
- One-component expanding polyurethane foam filler
- Expands 35–40 times its initial volume
- 25% more linear yield than standard Soudafoam FR
- Fire rated to EN13501-2 class E and EN1366-4 (up to 4 hours fire resistance)
- Rapid curing with excellent thermal and acoustic insulation properties
- Primerless adhesion on most construction materials
- Loose packaging for convenience
Fitment & Application Tips
To ensure optimal performance, follow these guidelines:
- Ensure substrate surfaces are clean and free from grease and dust before application.
- Moisten surfaces with water prior to foam application.
- Shake the aerosol can for at least 20 seconds before use and regularly during application.
- Fill cavities only one-third at a time to allow for proper expansion.
- Test adhesion on non-conventional substrates before full application.
- Use appropriate cleaning agents for fresh foam removal and mechanical means for cured foam removal.
Common Ordering Mistakes
Avoid these pitfalls when ordering:
- Failing to confirm compatibility with the substrates to be sealed.
- Neglecting to prepare surfaces by cleaning and moistening prior to application.
- Overfilling cavities without allowing for expansion.
- Not shaking the aerosol can sufficiently before and during use.
