Wool is the ideal natural fibre to use in thermal insulation. Not only do wool fibres enable excellent thermal efficiency, they can act as a humidity buffer and absorb indoor air pollutants such as formaldehyde, helping create a healthier indoor climate.


In the UK alone, 36 million sheep produce around 70 million kg of wool, locking up nearly 140 million kg of CO2 from the atmosphere.  That's the equivalent to the CO2 emissions from nearly 35,000 family cars.  What's more the wool is regenerated as the fleece regrows so this process is repeated every year.

Wool is a hygroscopic fibre and is capable of absorbing more moisture than any other natural fibre due its high fibre saturation point.  This means that wool can absorb nearly 40% of its own weight in moisture and still feel dry to the touch.  Because wool binds moisture rather than just absorbing it, the performance of our insulation does not vary significantly as humidty levels in the building change.  This can help contribute towards a more comfortable and healthy indoor environment.

The complex protein structure of the wool fibre enables it to absorb and safely fix many airborne substances that can be harmful in the indoor environment, including formaldehyde, which is released from many fabricated materials in the home.  Amongst natural fibres, this is a property that is unique to proteins such as wool.

Because THERMAFLEECE is made from the same materials commonly used in clothing and fabrics, it can be safely recycled at the end of its life into a variety of uses.
