PremFire B2 Elastic Gun Foam is a one-component, ready-to-use polyurethane gun foam for various building applications, e.g. installation of window and door frames, sealing of joints and penetrations, thermal and acoustic insulating. Ensures good results all year round. Near-zero curing pressure and low post expansion avoid deformation of building elements. Adheres well to most materials like wood, concrete, stone, plaster, metal, PVC and polystyrene.
