The Right Insulating Material Product Idea

  • Cold Insulation

  • Heat Insulation

  • Noise Insulation

  • Reduced Energy Costs

  • Saving of Resources

  • Value Creation



Innovative JRS HPC Fibrillation results in maximum fiber resilience, which means that there is virtually no likelihood that ARBOCEL® CLIMASAFE will sink when it settles. This in turn means a noticeable saving in materials and thus reduced costs.



  • DIN ISO 9001:2008 certified quality management
  • DIN ISO 500001 certified energy management
  • Environmental handbook based on DIN ISO 14001 (Environment Management System)


  • Fast, clean, simple
  • Using blowers
  • In cavities (e.g. for timber-framed structures)
  • No joins, continuous without thermal bridges
  • No cutting
  • Uncomplicated transport inside the building using a hose

Safety tested to protect people and the environment

  • No volatile substances
  • Saves resources
  • 100% recycling material requires the lowest use of primary energy during manufacturing of all insulation materials (approx. 55 - 70 kWh/m³)
  • Can easily be recycled when removed by skilled professionals
  • No hazardous substances as per ETA-13/410
  • Contains no ammonium compounds


  • No dripping in the event of a fire
  • Fire-resistant thanks to added boron salt
  • Pest-proofed using boron salt

Optimum protection

A special, low-dose boron salt is used to make ARBOCEL® CLIMASAFE fire- and pest-resistant. Approved by the German Federal Health Office this is the environment-friendly choice within the range of available protective substances. It is odourless and non-volatile. Perfect to integrate flame- und pest-resistance into a highly functional, user-friendly product. The boron salt is homogenously distributed using an innovative procedure developed by JRS, during which it is optimally combined with the fibers without any losses caused by separation. This in turn means that it is possible to reduce the concentration of boron salt to an absolute minimum while still retaining maximum efficacy!
