ThermaFleece CosyWool 50mm Slab 570mm

50mm ThermaFleece CosyWool Slab 570mm provides flexible, high-performance thermal and acoustic insulation with excellent value. This wool-rich, thermally bonded slab offers durability and long-term stability without settling. Testing confirms this fibre blend outperforms higher wool-content alternatives, delivering the benefits of sheep's wool insulation with superior breathability, resilience, and environmental credentials.

Wool is an exceptional natural material. As sheep's fleece develops, it naturally captures carbon dioxide from the air. When installed as insulation, it traps airborne contaminants that could affect health, fostering a cleaner living space. Fitting 50mm CosyWool Slab 570mm substantially boosts building energy efficiency and lowers heating expenditure.
