When you need hand held fire rated expanding foam that actually meets a recognised fire classification, this is the one to reach for. Soudafoam B2 is a one-component, self-expanding polyurethane foam supplied in a standard 750ml handheld can — no applicator gun needed, just the straw nozzle that comes with it. It meets German Fire Class B2 under DIN 4102-Part 1, which makes it suitable for use wherever a degree of fire resistance is required around building penetrations and service entries.
The propellant is completely CFC-free, so there is no ozone impact from using it. It cures by reacting with moisture in the air and in the substrate, expanding to fill the cavity before setting firm. Once cured, the foam forms a tight, rigid seal that resists air movement and provides the fire resistance the job calls for.
Most standard expanding foam is fine for draught sealing and general gap filling, but it offers no meaningful protection in a fire situation. Soudafoam B2 is the correct choice when you are sealing around pipes, cables, conduits or ductwork passing through fire compartment walls or floors. It is the kind of product that tends to get specified, and rightly so — using the wrong foam in a fire-rated application is not a shortcut anyone wants to take.
Where Handheld Fire Rated Expanding Foam Gets Used
The handheld format is ideal for single trades working on relatively contained jobs. Electricians, plumbers and mechanical engineers use it regularly when making good around service penetrations. It works equally well on new-build projects and refurbishments, anywhere the spec calls for a fire-rated seal at a gap or void.
Ease of Use on Site
Ready to use straight from the can. Shake well, attach the straw nozzle, and apply from the bottom of the cavity upward. The foam expands to roughly two to three times its dispensed volume, so fill the gap partially and let it do the work. Trim any excess once fully cured.
Pro Tip: Lightly dampen the surfaces and cavity with water before applying — polyurethane foam cures by reacting with moisture, and a damp substrate will give you a more consistent cure and better adhesion, especially in dry conditions.
