Ecological parameters

Our ISOLENA sheep's wool insulation not only impresses with its natural properties, but also with its outstanding environmental performance. The Environmental Product Declaration (EPD) shows that our insulation makes a positive contribution to sustainability in the construction industry. We would like to emphasise the CO₂ balance: Sheep's wool binds large amounts of CO₂ as it grows. This natural carbon storage ensures that our insulation stores more CO₂ than it emits over its entire life cycle.

  • Total CO₂ balance: -19,3 kg CO₂ equivalent per m³ → Climate-positive thanks to natural CO₂ storage

All other ecological indicators according to EN 15804 such as GWP total, GWP biogenic, PENRT etc. can be found in the Environmental Product Declaration (EPD).
