Product Description

Thermafleece CosyWool is a versatile insulation rich in British sheep's wool and is the ideal choice if you are looking for all round performance and value for money.

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.

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.
