Natures Finest Insulation.
Thermafleece CosyWool slab is a versatile insulation made from 75% British sheep’s wool and 25% recycled polyester.
A great choice for insulating walls and roofs.
Research shows that using 75% wool in combination with recycled fibres outperforms alternative products with a higher percentage of wool.
Our wool rich blend ensures you get the full benefit of sheep’s wool with enhanced performance, breathability, durability and sustainability.
CosyWool Slabs are flexible but denser than rolls and sized to provide extra tight friction fit in walls and roofs providing excellent thermal and acoustic performance.
Thermafleece CosyWool flexible slabs are harmless and can be installed without gloves or protective clothing, although we recommend you wear a dust mask in enclosed spaces such as lofts.  Thermafleece CosyWool is not irritating to the skin, eyes or respiratory tract.

To retain the benefits of water vapour, absorption and release, Thermafleece CosyWool  flexible slabs may be used in conjunction with a vapour permeable underlay. Protect the insulation from prolonged exposure to sunlight when unpacked and avoid wetting for extended periods, store under cover and clear of the ground.
