Product Description

Thermafleece UltraWool is a high density ultra-efficient insulation rich in British sheep’s wool and is the ideal choice if you are looking for maximum thermal performance when space is at a premium.

With a density of 31 kg/m3 Thermafleece UltraWool also helps provide exceptional acoustic insulation performance in wall, floor and roof systems.

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.

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.
