IONIC PROTECT® Wool protection

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.
