Parafoam Flexible NBS


  • One-component PU gunfoam
  • Elastic foam, absorbs movements of surrounding materials perfectly and prevents foam tearing or cracking
  • All-season foam, can be used at an ambient temperature starting from -5°C to 30°C
  • High volume - moderate post expansion (extremely low curing pressure)
  • Good thermal and acoustic insulation
  • CFC- and HCFC- free (ozon friendly)
  • Accurately controlled application with NBS gun
  • No hardening behind the safety valve, no intrusion of moisture
  • Cured foam can be cut, sawn, plastered and painted and is resistant against water


  • Ideal for durable insulation in low-energy and passive homes.
  • Ideal for motion sensitive joints.
  • Sealing of windows and doors.
  • Filling of voids and gaps (in roof constructions).
  • Excellent adhesion to wood, concrete, stone, plasterwork, metals, polystyrene, hard PVC, etc.
