High yield fire rated, one component gun grade polyurethane expanding foam. 25% higher yield than ...High yield fire rated, one component gun grade polyurethane expanding foam. 25% higher yield than standard Soudafoam FR fire resisting foam. The rapid curing foam filler provides excellent thermal and acoustic insulation properties. Expands 35-40 times its initial volume. Very good adhesion on most construction materials. Suitable for use in passive fire protection systems as a large gap filler, as well as the installation of fire retardant window and door frames. Fire resistance: up to 4 hours. Reaction to fire: class E. Excellent thermal & acoustic values.
This guide is for professionals seeking a high-yield, fire-resistant expanding foam for construction applications. The Soudal Soudafoam FR provides excellent thermal and acoustic insulation and offers up to 4 hours of fire resistance, making it ideal for fire-stopping and sealing gaps. However, users should be aware of the rapid expansion rate, which requires careful application to avoid overfilling.

Troubleshooting
Foam does not expand properly.
Ensure the can has been shaken well, the temperature is within the recommended range, and the surface is adequately prepared.
Foam gun clogs.
Clean the foam gun immediately after use with a foam gun cleaner. Do not leave the can attached to the gun for extended periods.
Foam expands too much.
Apply in thin layers and allow each layer to expand before adding more. Avoid overfilling the gaps.
Poor adhesion.
Make sure the surface is clean, dry, and free of dust and grease. Consider priming highly non-porous surfaces.
Pros and Cons
Pros
High fire resistance rating (up to 4 hours).
High yield, providing more coverage per can.
Excellent thermal and acoustic insulation.
Suitable for various construction materials.
Easy to apply with a gun grade applicator.
Rapid curing time.
Cons
Rapid expansion requires careful application.
Can be messy if not applied correctly.
Requires a foam gun for application.
Material waste if over-applied.
Class E reaction to fire rating may not meet all building codes.
Specific application techniques are needed.
Setup, Compatibility & Care
Preparation: Ensure the surface is clean, dry, and free of dust, grease, and loose particles. Protect surrounding areas from overspray.
Gun Attachment: Attach the can of Soudafoam FR to a compatible foam gun.
Application: Shake the can vigorously for at least 20 seconds. Apply the foam in layers, allowing each layer to expand before applying the next. Avoid overfilling, as the foam will expand significantly.
Curing: Allow the foam to fully cure according to the manufacturer's instructions (usually a few hours). Curing time depends on temperature and humidity.
Trimming: Once cured, trim away any excess foam with a knife.
Compatibility: The product is compatible with most common construction materials but always test on a small area first.
Care: Store cans in an upright position in a cool, dry place. Protect from direct sunlight and extreme temperatures.
