Parafoam Flexible NBS

Gun foam with high elasticity. The foam perfectly catches all joint movements from the surrounding materials, so the foam does not crack. Ideal for durable insulation in low-energy and passive homes. This foam cannot be used for assembly purposes. Excellent acoustic insulation. 

  • 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
Parafoam Flexible NBS is available to buy in increments of 12.
