1c Premium gun foam PUP B1 750

The hardly flammable B1 one-component gun foam

The fischer hardly flammable gun foam PUP B1 750 has high flame resistance as per building material class B1 of DIN 4102-1. This makes it suitable for the filling and sealing of joints with fire protection requirements. In addition, it is suitable for the highly effective thermal insulation of ETICS façades. The gun foam is also used for fixing and sealing in roofs and walls and for sealing window connection joints. The easy dosability enables controlled filling and insulation as well as saving on costs. The grey fischer PUP B1 750 has a solid valve that offers top security against blockages and the loss of gas. Protective gloves for end users are included.

  • The new high-quality safety valve prevents adhesion when being stored horizontally or during long interruptions of work, thus guaranteeing long-lasting functionality.
  • The easy dosage allows for a controlled filling and sealing, and ensures that the correct amount is used.
