Plus points of sheep's wool

The healthy and sustainable virgin sheep's wool naturally achieves the best insulation values and offers a unique combination of product benefits like no other insulation material.

The natural virgin sheep's wool is able to purify the room air of many odours and pollutants, such as the widespread formaldehyde, within a very short time.

Sheep's wool can absorb up to 33 % of its own weight in moisture without losing its insulating effect. In a dry environment, the wool releases the moisture again.

Sheep's wool has an auto-ignition temperature of 560 - 600° C. This is about twice as high as that of wood. It melts away from any heat source without dripping.

Sheep's wool has very good sound absorption properties due to the different fibre fineness of the wool fibres and is therefore suitable for demanding acoustic optimisations.

Pure new sheep's wool is a renewable raw material and 100 % compostable. ISOLENA insulating wool is selected according to ecological standards, contains no insecticides and can boast the natureplus® test mark.
