ISOLENA Optimal
Density: 18 kg/m³
Application: Roof extension, ceiling - overhead insulation, interior & exterior walls, room air renovation in interior construction: partition walls, installation level, timber construction
Our ISOLENA Optimal sheep's wool insulation consists of 100% wool protected with Ionic Protect® and is renewable, durable, recyclable and manufactured without synthetic additives.
- The multiflexible thermal and acoustic insulation is the best solution for standard applications up to 140 mm insulation thickness.
- The thickness is elastic and also encloses cable ducts without further processing.
- Slight oversizes in the width adapt flexibly to the construction.
- The insulation roll with carrier felt is ideal for quick, mechanical fastening in horizontal and inclined supporting structures (rafters, frames, transoms, etc.).
- Quick installation, ideally suited for work overhead.
- No dust mask and no protective clothing necessary.

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).
