Wool protection: Ionic Protect
With Ionic Protect®, Lehner offers the only biocide-free wool protection worldwide. It is a plasma ion treatment of wool fibres with the aim of protecting them from all negative influences that can occur in construction. Ionic Protect® means that the ISOLENA products are retardantly and permanently biocide-free protected on a plasma-ionic basis against. This unique treatment method is only carried out by us and gives the sheepwool all the properties that are necessary for its durable function as an insulating material. The functionality is tested and confirmed in the laboratory, protected by trademark patent, natureplus-certified and tested according to EAD/CUAP standard.
For ISOLENA we only use very well washed virgin sheep's wool. As a matter of principle, we do not add any synthetic additives or adhesive fibres and use our biocide-free, certified wool protection Ionic Protect®. This processing not only clearly sets us apart from our competitors, but also preserves all the natural properties of the fibre.
