Soudal Expanding Foam 750ml Gun Grade Gap Filler

The Soudal Gap Filler Expanding Foam is a high-performance polyurethane foam designed for filling, sealing, and insulating gaps, voids, and joints across a wide range of construction and installation tasks.

This gun-grade expanding foam delivers controlled application and high yield, making it ideal for professional use where accuracy and efficiency matter. It expands to fill irregular spaces and provides strong adhesion to most building materials.

Use it around window and door frames, pipe penetrations, roof voids, and electrical installations to create an airtight and insulated seal. Once cured, the foam can be cut, sanded, plastered, or painted, allowing for a clean and professional finish.

With excellent thermal and acoustic insulation properties, it improves energy efficiency while reducing noise transfer. Its stable formulation prevents shrinkage or post-expansion, ensuring long-lasting performance.
