CosyWool Roll is versatile home insulation rich in British wool and is the ideal choice if you are looking for all round performance and value for money.


Made from 75% British wool and 25% recycled polyester. Research shows that using 75% wool in combination with recycled fibres outperforms alternative products with a higher percentage of wool.

Their wool rich blend ensures you get the full benefit of sheep’s wool with enhanced performance, breathability, durability and sustainability.

Thermafleece CosyWool Roll’s convenient compressed form reduces transport impacts by more than 50% compared to other natural fibre insulation and makes it ideal for quick and easy installation.
