Soudal is a world leader in polyurethane expanding foams, manufacturing over 130 million cans every year. Each foam in the range is built for high yield, strong adhesion, and lasting durability, trusted by Australian builders and tradespeople across residential, commercial, and industrial projects.

A Foam for Every Job

The Soudal expanding foam range includes options for precision, flexibility, and speed of application. Choose the format that best fits your project needs.

Gap Filling Expanding Foam – Smart Foam

Gap Filling Expanding Foam – Smart Foam features an integrated applicator for single-handed control without needing a foam gun. It’s ideal for small to medium sealing jobs, offering a clean and consistent flow. Reusable for several weeks after opening, Smart Foam resists shrinkage, cures quickly, and provides a water-resistant, airtight seal.

Gap Filling Expanding Foam – Straw

Gap Filling Expanding Foam – Straw is a simple, ready-to-use option for filling and insulating larger cavities. Its attached straw nozzle makes it quick to apply on-site, perfect for sealing around pipes, conduits, or voids. Once cured, it can be trimmed, sanded, plastered, or painted for a professional finish.

Gap Filling Expanding Foam – Gun Grade

Gap Filling Expanding Foam – Gun Grade provides precision control for professional users. Applied with a foam gun, it’s ideal for high-volume jobs such as wall cavities, roof voids, and frame mounting. The dense cured foam offers excellent thermal and acoustic insulation and can be cut and painted once hardened.

Flexible Insulation Foam – Gun Grade

Flexible Insulation Foam – Gun Grade delivers flexibility where movement is expected. It’s perfect for use around windows, doors, and frames, maintaining its seal even when materials shift over time. It also provides an acoustic insulation rating of 60 dB, improving noise reduction in homes and buildings.

Soudafoam SMX

Soudafoam SMX is a low-VOC, isocyanate-free foam designed for sensitive environments and “healthy home” projects. Using advanced SMX polymer technology, it provides strong adhesion to most porous substrates, including slightly damp surfaces. It’s the ideal option for builders prioritising indoor air quality and safety.

Fire-Rated Foams: Up to 240 Minutes of Protection

Soudal’s fire-rated foams provide up to four hours of fire resistance in tested systems. Available in both gun-grade and aerosol formats, they seal gaps to prevent the spread of smoke and gas while bonding firmly to construction materials. Once cured, they remain dimensionally stable and can be plastered or painted.

Duravalve Technology: Consistent Flow and Less Waste

All gun-grade Soudal foams feature Duravalve technology, ensuring consistent pressure, optimal yield, and reduced material loss. The valve design keeps the can sealed and ready for reuse, even after being stored horizontally.

Where You Can Use Soudal Foam

Structural and service penetrations

Seal around pipes, conduits, and roof voids to create airtight and watertight joints. Gun-grade foams deliver the accuracy needed for energy-efficient builds.

Joinery, doors, and windows

Flexible Insulation Foam is ideal for window and door frames, maintaining a tight seal and preventing cracking as materials move.

Insulation and cavity filling

Use Gap Filling Expanding Foam or Soudafoam SMX to fill wall, floor, and ceiling cavities. Both options combine air sealing with thermal insulation for long-term performance.

Fire and acoustic protection

Fire-rated foams offer tested resistance for compliance and safety, while flexible foams help improve noise reduction.

Final Thoughts

From flexible sealing to fire-rated insulation, Soudal’s expanding foam range gives Australian tradies a reliable solution for every project. With options for precision, speed, flexibility, and sustainability, it’s easy to find the perfect foam for your job.
