Soudal Pro Expanding Foam Gun Grade
Soudal Pro Expanding Foam Gun Grade is a one-component, ready-to-use polyurethane gap-filling foam with a threaded canister for use with a foam gun, giving tradespeople precise, controlled application on high-volume work. Its HCFC- and CFC-free propellants are not harmful to the ozone layer.
Thanks to the Duravalve, the can holds its optimal yield across its whole shelf life, even when stored or transported lying down, so you get full value from every canister. It delivers high filling capacity with high thermal and acoustic insulation, making it a workhorse for filling, sealing and insulating around frames, joints and penetrations. Pair it with a Compact PU Foam Gun and see the full expanding foam range.

Features & Benefits
- Gun-applied control: Precise bead control for high-volume professional filling and sealing.
- Duravalve technology: Optimal yield across the full shelf life, even stored or transported lying down.
- High filling capacity: Fills larger gaps and cavities efficiently.
- High thermal and acoustic insulation: Reduces heat loss and sound transfer.
- Excellent stability: No shrinkage or post-expansion once cured.
- Good adhesion: Bonds on most surfaces (except PE, PP and PTFE). Not UV-resistant, so coat exposed foam.
Why Choose Soudal Pro Expanding Foam Gun Grade?
Built for control on big jobs. Applied through a foam gun, it gives precise bead control for high-volume filling and sealing.
Full yield, every can. The Duravalve keeps yield optimal across the shelf life, even after the can is stored or transported on its side.
Fills and insulates in one. High filling capacity plus high thermal and acoustic insulation seals and insulates around frames and penetrations.
Holds its shape. Excellent stability means no shrinkage or post-expansion after curing.
Applications
This product is suitable for installing window and door frames, filling cavities, and sealing openings in roof constructions. It can also be used to create an acoustic baffle and to improve thermal insulation in cooling systems.

FAQs
What is gun-grade expanding foam used for?
Gun-grade foam is designed for high-volume filling, sealing and insulating where you want precise control. It threads onto a foam gun so you can lay a controlled bead around frames, joints and cavities.
What is the Duravalve and why does it matter?
The Duravalve keeps the can’s yield optimal across its full shelf life, even when stored or transported lying down. In practice that means you get reliable output from the can rather than losing pressure or yield over time.
Which foam gun should I use with it?
Use a Soudal PU foam gun such as the Compact PU Foam Gun, which threads onto the canister for controlled application. Clean the gun with Gun & Foam Cleaner between uses to keep it working.
Is the foam UV resistant?
No, cured foam is not UV-resistant and should be coated or covered for outdoor use. Leaving it exposed to sunlight will degrade it over time.
Where can I buy Soudal Pro Expanding Foam Gun Grade in Australia?
It is stocked at Soudal trade outlets across Australia in 750ml cans. You can find where to buy at a Soudal stockist near you
