Product Overview
A B2 fire-rated, quick-curing polyurethane foam filler that provides strong adhesion and high thermal and acoustic insulation. Suitable for bonding, sealing, filling, and insulating a wide range of building materials including wood, concrete, plaster, metal, PVC, and polystyrene. Ideal for controlled backfilling, gap filling, insulation of penetrations, and sealing joints and insulation boards.
This B2-rated polyurethane expanding foam is designed for fast, effective bonding, filling, and sealing across a wide range of construction applications. The cured foam delivers strong adhesive properties along with excellent thermal and acoustic insulation performance, making it suitable for both structural and finishing work.
With low curing pressure and reliable expansion, the foam ensures clean backfilling and effective gap sealing. It adheres well to common building materials such as wood, concrete, stone, plaster, metals, PVC, and polystyrene. Available in both aerosol and gun-grade versions, it offers flexibility for professional and DIY use.
