Soudal PU Assembly Foam Cartridge 750 ml (winter) — low-pressure winter formula for cold conditions

Soudal PU Assembly Foam Cartridge 750 ml (winter) is a winter-grade polyurethane foam formulated for reliable application in low-temperature conditions. Supplied in a 750 ml cartridge compatible with standard applicator guns, this low-pressure foam is designed to expand after application to seal, fill and insulate joints, gaps and cavities around windows, doors, pipes and other building elements. The winter formulation maintains workable flow and adhesion at reduced temperatures, enabling use on colder job sites where standard foam may not perform.

Advantages

The low-pressure winter formula provides controlled expansion to reduce risk of excessive bulging and overfill, which helps achieve neater finishes. Good adhesion to common construction substrates such as wood, concrete, brick and many plastics ensures durable sealing and fixing. The product offers thermal and acoustic insulating properties once cured, improving energy efficiency and sound reduction in partitions and openings. Compatibility with standard applicator guns allows straightforward application without special equipment, and the winter grade extends the application temperature range compared with standard foams.

Suitable for

• Sealing and insulating gaps around exterior and interior windows and doors in cold climates
• Filling cavities and voids in masonry, timber frames and stud walls
• Anchoring and fixing window and door frames, pipes and conduit penetrations
• Thermal and acoustic insulation of joints, seams and service entries during renovation and new build work

Key specifications

• Volume: 750 ml cartridge
• Foam type: Polyurethane, low-pressure formulation
• Temperature performance: winter-grade suitable for low-temperature application
• Application method: compatible with standard applicator gun
• Performance: expanding foam providing sealing, filling, thermal and acoustic insulation

How to use

Surface preparation is required: substrates should be clean, stable and free from dust, grease and loose particles. Shake the cartridge well before use and attach it to a compatible applicator gun. Apply foam into the prepared gap or cavity in layers if filling deep voids, allowing partial curing between passes. After curing, excess foam can be trimmed, sanded and finished with suitable sealants or paints if necessary. Observe manufacturer instructions for curing times and safety measures such as ventilation and protective gloves.

Usage recommendations

For best results in cold conditions, store cartridges at recommended temperatures before use and maintain steady, controlled application to avoid overfilling. Use personal protective equipment and follow local safety guidelines for handling polyurethane foams. Test adhesion on unfamiliar substrates prior to large-scale application.
