ThermaFleece CosyWool 100mm Slab 570mm

100mm ThermaFleece CosyWool Slab 570mm is a flexible, high-performance insulation solution delivering comprehensive thermal and acoustic benefits at competitive pricing.

Manufactured from a wool-rich fibre blend that's thermally bonded, this 100mm slab provides exceptional durability and dimensional stability, resisting compression throughout its lifespan. Testing demonstrates this blend achieves superior performance compared to higher wool-content alternatives, combining the advantages of sheep's wool insulation with improved breathability, resilience, and environmental credentials.

Sheep's wool is an exceptional natural material. As fleece develops, it naturally captures carbon dioxide from the air. When incorporated into insulation, it traps airborne pollutants that could affect health, fostering a superior indoor atmosphere. Installing 100mm CosyWool Slab 570mm represents an efficient approach to enhancing building energy performance and lowering heating expenditure.
