Sheep's wool insulation


Item number: PRE02000BR24
Density: 20 kg/m³
Application: Roof Extension, Ceiling – Overhead Insulation, Storey Ceiling, Tie-beam Roof, Interior & Exterior Wall, Wooden Construction

Our ISOLENA Premium sheep's wool insulation is made of 100% wool and is renewable, durable, recyclable and manufactured without synthetic additives.

  • The compact thermal and sound insulation in high insulation thicknesses from 120 to 300 mm in one (single layer!) insulation roll.
  • The thickness is elastic and also encloses cable ducts without further processing.
  • Small excesses in width flexibly adapt to the construction.
  • The insulation roll for the installation in horizontal and inclined supporting structures (rafters, frames, transoms, etc.).

We manufacture ISOLENA Optimal Plus in the following standard dimensions:

IONIC PROTECT® is a biocide-free process developed by ISOLENA and protected by a trademark patent to protect wool.

Plasma ion treatment of the wool fibres protects them from all negative influences that can occur in construction. This gives moths and insects no chance to thrive. In addition, our products can be stored indefinitely thanks to the wool protection.

We present you with these terms in writing with the ECO/CUAP test report ECO-P16002-15017 and our product promise.
