The new Neopor® F 5 PRO

BASF extends its Neopor® portfolio, presenting the newly developed Neopor® F 5 PRO, optimized for perimeter and flat roof insulation.

The New Product in Neopor® F 5000 Series

Main properties:

  • Particle size: 0.9–1.4 mm
  • Contains polymer flame retardant and graphite
  • Low pentane content: ~4.5%
  • For fire classification E (EN 13501-1)
  • High insulation performance
  • For boards with very low long-term water absorption by immersion (EN 12087) and diffusion (EN 12088)

Processing characteristics:

  • Processing in batch pre-expanders and moulded in shape-moulding machines
  • Typical density range: 25–35 kg/m3
  • Short cycle timet
  • Very good welding


In perimeter insulation as well as in inverted roofs, insulation boards made of Neopor® F 5 PRO are above the sealing layer, protecting it from harmful environmental impacts, especially temperature changes and mechanical stresses. Thanks to their low water absorption properties, they keep a high insulation performance even when in contact to water.
