This sheep wool insulation has went through a very clever manufacturing process that alters the molecular protein structure of the wool fibre through a plasma-ion treatment. This specific process is unique as it permanently prevents the wool from being a nutritional source for wool parasites.

What about fire safety?

The natural fibres of the sheep wool have a self-combustion temperature of 560 – 600 °C . This high flash point is around twice as high as that of wood ( 270 ° C ) . It also melts away from a heat source without dripping. It requires no flame inhibitor so therefore generates no poisonous gases in the case of fire.

There is no inflammation when electric wires cut short and also smells when lighted – this acts as a biological alarm function. The European Fire Classification is D.
