Field of application

  • Insulation of pipelines in the field of refrigeration
  • Specially suitable for attachments in ventilation, air-conditioning, heating, refrigeration installations as well as for hot and chilled water pipes


  • Rigorous avoidance of temperature bridges in cold pipelines
  • Highly effective insulation due to support elements made of PIR and a synthetic rubber mantle
  • Insulation thickness matched to the increasing insulation layer thickness of the insulation sleeves
  • Rubber surfaces on the face sides allow easy bonding with the rubber pipe insulation
