Pro Expanding Foam Genius 500ml Soudal

Professional-grade expanding foam that fills gaps, cracks, and voids while providing thermal and acoustic insulation.

Soudal's Genius formula seals air leaks and blocks drafts to improve energy efficiency and comfort. Trigger-control applicator enables one-hand operation for precise, easy application.

Compatible with wood, metal, concrete, drywall, and most building materials without affecting electrical cables. Once cured, the rigid foam can be trimmed, sanded, painted, or plastered for a seamless finish.

Suitable for both internal and external use—outdoor applications benefit from UV protection. The unopened can remains usable for up to 6 weeks, reducing waste on multi-stage projects.

Ideal for sealing windows, doors, pipes, and structural gaps in residential and commercial work.
