puren NE-B2

puren NE-B2 insulating elements are ideally suited for cost-effective insulation of flat roofs with increased pressure loads such as green roofs, patio roofs etc.

puren NE-B2 flat roof insulation

puren NE B2 TCG (WLS) 026/027/028

Insulating elements made of high-performance PUR/PIR rigid foam (polyurethane), DIN EN 13165, TCG (WLS) 026/027/028 (TCG (WLS) 026 ≥ 120 mm, TCG (WLS) 027 ≥ 80 mm, TCG (WLS) 028 < 80 mm), building material class B2, application type PUR 026 DAA ds, or PUR 027 DAA ds, or PUR 028 DAA ds, non-laminated.


  • Low superstructure because of high thermal insulation
  • Saving costs because of shorter fastening elements
  • Can be laid in hot asphalt
  • Safe processing of roofing foil by pouring and rolling or welding it in
  • Insulating elements may be used either way up for cost-efficient fitting with low off-cut waste
  • Can be used from -20 °C to +110 °C
  • Limit to short-term temperature exposure: +250 °C
  • Compressive strength at 10 % compressive deformation in accordance with DIN EN 826:
  • 150 kPa (higher compressive strength > 150 kPA - 880 kPA upon request)
  • Water absorption acc. to DIN EN 12087: approx. 3 % by volume
  • Walkable, suitable for installing into high-stress surfaces such as parking roofs
  • When laid onto trapezoidal corrugated steel, the insulation will not be torn when stepped on
  • Laminated roof structures offer high resistance to wind suction forces
  • Low additional load on the roof construction
  • High age-resistance
  • Resistant to chemicals and solvents typically used in building & construction and many others
