Features and benefits:

  • Class A1 to EN 13501-1.
  • Fire resistance: Up to two hours (E 120/ I 120) to EN 1366-4.
  • Third party approval – Certifire CF 5727.
  • Sound reduction: Up to 25 dB (Rw).
  • Integral smoke barrier.
  • Resilient to accommodate site tolerances without cutting.
  • Friction fit options for green brickwork installation.
