Soudal B1 Fire & Acoustic PU Foam Gun Grade 750ml

Designed for demanding building and renovation work, Soudal B1 Fire & Acoustic PU Foam Gun Grade is a fire-rated polyurethane foam filler with strong acoustic insulation and thermal properties. It is well suited to insulating roofing materials, sealing around pipe penetrations and fitting neatly around window frames, making it a practical choice for a wide range of construction projects where performance matters.

Formulated to support fire resistance and sound reduction, this gun-grade foam is rated to EN1366-4 for up to four hours’ fire resistance depending on joint configuration, with a DIN 4102 B1 fire class. An acoustic rating of 58 dB and an insulation factor of 36mW/mK help it contribute to quieter, better-insulated spaces when used in appropriate applications.
