What is 100%Sheepwool Premium Insulation?

The wool is primarily fine black fleece wool. Black wools maintain all the desirable characteristics of white wools, but are less expensive due to limitations of the colour in the dying process. The final colour of the product is dependent on the blend used during production and is likely to vary. Wool fibres have many overlapping scales which make them very flexible and create a memory-effect, where after significant compression, wool will return to its original shape. Wool fibres are hygroscopic by nature and will have a moisture weight content of up to 35%, dependent on the relative humidity of the surroundings. While absorbing this moisture, wool releases energy in the form of heat, thus raising the temperature of its surrounding areas. Naturally releasing this moisture in the warmer seasons, wool creates a cooling effect on the same surroundings.

** Thorlan IW is applied at a level of at least 1% on weight of wool. Thorlan is a titanium based treatment which does not evaporate or diminish with time and remains with the fibre during it’s entire period of use as insulation or in storage prior to that. It is applied chemically to the wool fibre and cannot be removed mechanically. Thorlan IW is not destroyed by washing, humidity or by long continued exposure to UV-radiation. The active substance is not inclined under usual conditions to sublimation. The production of the active substance takes place in a standardised procedure. The product quality is constantly supervised. Thorlan IW is in the European Union chemical law register of certified products.
