the genfoam series is a closed-cell compression foam system delivering watertight, dustproof, airtight, and thermally insulating performance in a single product. designed for a wide range of gap sizes from 50mm to 200mm across all building surfaces.
suitable for floor, wall, and ceiling applications in interior, exterior, and below-grade environments. the pre-formed closed-cell foam expands to fill the joint gap while maintaining consistent compression for reliable sealing performance.
compress and insert into the expansion gap with no mechanical fixings, adhesives, or special tools required. the foam naturally expands to create a tight, uniform seal against the joint faces.
