 Sheep's wool is the only natural insulating material that both stores heat and protects against heat, cold and moisture. Its special properties also make sheep's wool a material with outstanding advantages in the finished product that cannot be found in other products of this kind.


Sheep's wool - naturally insulated, perfect

ISOLENA sheep's wool insulation materials offer excellent insulation values in every season, keeping you cool in summer and warm in winter, which no other product in this class can match. With a low thermal conductivity of 0.033 - 0.042 W/mK, they offer excellent insulation. The lower this value is, the better the insulating effect, which makes ISOLENA particularly efficient.



Clean air, thanks to sheep's wool - nature makes it possible!


Sheep's wool naturally ensures a healthy indoor climate by breaking down harmful substances such as formaldehyde and neutralising odours. Thanks to the keratin it contains, it binds pollutants permanently. The closer the wool is installed to the interior, the better its effect on the indoor air. ISOLENA sheep's wool insulation also guarantees that no fibres are released into the room air.




Humidity regulation for healthy rooms

Damp walls irritate your health and restrict your well-being. Sheep's wool naturally regulates moisture in rooms by absorbing up to 33% of its own weight in moisture without losing its insulating quality. It releases the moisture again if the air is too dry and remains dimensionally stable and dry. Thanks to its hygroscopic properties, sheep's wool is ideal for damp environments and protects the building fabric from damage. In addition, it does not provide a breeding ground for mould, which contributes to healthier indoor air.



Meet the highest standards of quality and safety

With ISOLENA, rooms can be better protected in a natural way.



Sheep's wool - Natural fire protection at the highest level

Sheep's wool offers excellent fire protection thanks to its high self-ignition temperature of 560-600 °C, which is twice as high as wood. It melts in heat without dripping and, depending on the product, achieves fire protection classifications of B1, C or D in accordance with EN 13 501-1. Thanks to the 100% use of virgin sheep's wool, the innovative ISOLENA processing technology and the biocide-free wool protection IONIC PROTECT®, ISOLENA offers maximum safety in fire protection.

Sound insulation for clear communication

ISOLENA acoustic products made from sheep's wool offer excellent sound insulation and are increasingly being used in schools, nurseries, office buildings and private homes. Thanks to its special fibre structure, sheep's wool absorbs sound efficiently and ensures pleasant acoustics, even in demanding environments. Whether fitted with acoustic fleeces or sheep's wool felts, the products in suspended ceilings and installation levels offer a natural and effective solution for undisturbed communication.

Resistant to moths thanks to IONIC PROTECT®

Ionic Protect® is a patented process developed by ISOLENA that protects wool from pests in a natural way without biocides.


A special plasma ion treatment makes the wool fibres resistant to all common influences that can occur in the construction industry. This means that moths and other insects don't stand a chance. In addition, this protection ensures that ISOLENA products can be stored indefinitely.

Raw material for tomorrow: sustainable solutions from nature

ISOLENA utilises the natural properties of sheep's wool to develop environmentally friendly insulation materials. Sheep's wool insulation is ideal for ecologically-minded people, as only wool from live sheep has the necessary elasticity, bulkiness and durability to function as a high-quality insulating material and meet the highest quality requirements. ISOLENA stands for the future of sustainable construction and fulfils the highest quality requirements.
