Penosil PREMIUM FIRERATED GUN FOAM B1 Fire Rated PU Foam 750ml

Product Overview

Penosil PREMIUM FIRERATED GUN FOAM B1 is a fire-rated polyurethane gun foam specifically formulated for professional installation tasks, including filling and insulating cable, pipe penetrations, and mounting fire-resistant doors. Certified to EN 1366-4 and DIN 4102-1, it achieves fire resistance class EI 15-EI 120 and B1 (non-flammable), aligning with stringent European building and safety standards for commercial and industrial applications. Its quick curing time and adherence to multiple substrates make it suitable for demanding project environments requiring proven fire protection.

Unlike generic gun foams, this SKU is characterized by low post-expansion (maximum 30%), which helps prevent gaps or voids and ensures predictable dimensional stability in sealed joints. This detail is essential for contractors handling bulk installation in fire sealant projects, as it reduces rework and simplifies compliance with fire safety audits. The product is recommended for use by professional installers in commercial building refurbishments, fire door assemblies, and utility penetrations requiring certified fire-rated seals.
