Thermafleece CosyWool slab is versatile insulation rich in British sheep’s wool and is 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, 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’s convenient compressed form reduces transport impacts by more than 50% compared to other natural insulation and makes it ideal for quick and easy installation. Once unpacked, it regains its original thickness to provide excellent thermal and acoustic performance.

Like all Thermafleece products, it is long-lasting, safe to handle and contributes to a healthier indoor environment by regulating moisture and absorbing harmful airborne substances in the home.

Thermafleece CosyWool is manufactured and supplied in accordance with ISO 9001 quality and ISO 14001 environmental management systems.

Why Insulate With Thermafleece CosyWool?
  • Insulating a property will significantly reduce the amount of energy lost from the building envelope, reducing energy consumption and carbon dioxide released to the atmosphere. Affordable
  • Thermafleece CosyWool is designed to minimise up-front cost making wool based insulation more affordable to a wide range of end users.  What’s more, the energy it saves means Thermafleece CosyWool quickly pays for itself.
  • Long Lasting
  • Thermafleece CosyWool contains a lofting agent to maintain durability, fibre stability and structural integrity creating a long lasting insulation.
  • Quality Assured
  • Thermafleece CosyWool is manufactured and supplied in accordance with ISO 9001 quality and ISO 14001 environmental management systems.
  • Sustainable
  • Thermafleece CosyWool can reduce CO2 emissions by many tonnes over the lifetime of use.  What’s more, wool fixes carbon dioxide helping reduce greenhouse gas levels.
  • Breathable
  • Insulating with breathable natural fibres can contribute to more stable humidity and moisture levels within buildings.  This can help improve the health of the building and the occupants.
  • Safe
  • Thermafleece CosyWool is safe to handle and can be recycled or safely disposed of at the end of its life.
Installation and Handling

Thermafleece CosyWool is 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.

Thermafleece CosyWool can be used in conjunction with a vapour permeable membrane to retain the benefits of water vapour absorption and release.

Protect the insulation from prolonged exposure to sunlight when unpacked and avoid wetting for extended periods, store under cover and clear of the ground.

For accurate cutting, tightly compress or clamp the insulation between two pieces of solid 15mm board. Overhang the slab where you want to cut keeping the two board edges aligned.  Cut the edge with a scalloped edged knife and keep the blade firm and square against both board edges throughout.
