Thermafleece CosyWool Sheep's Wool Flexible Frame Slab Insulation is an affordable, long-lasting, denser and slightly wider natural British sheep’s wool insulation solution for an extra tight fit in roof, wall and floor applications. Ideal for timber frame wall, floor and roof jobs and made from 75% British Wool and 25% recycled polyester, this insulation choice is great for anyone looking for all-round performance and value for money.
Consistently shown to outperform alternative products with a higher percentage of wool, the special wool-rich blend ensures you get the full benefit of sheep’s wool to reduce the amount of energy lost from the building envelope, along with enhanced performance, breathability, durability and sustainability.
Easy to handle and install, CosyWool Slabs are flexible yet denser than rolls and sized to provide extra tight friction fit in walls and roofs, delivering exceptional thermal and acoustic performance. Like all Thermafleece products, these slabs are long-lasting, safe to handle and contribute to a healthier indoor environment by managing moisture and absorbing harmful airborne substances in the home.
Installation: CosyWool roll is non-hazardous and can be installed without gloves or PPE protective clothing, although we recommend you wear a dust mask in enclosed spaces such as lofts. You can easily tear Thermafleece apart, however more accurate edges can be achieved with the 'roll and cut' method using a sharp scalloped edge knife or insulation saw.
Suitable for lofts and warm roofs, timber frame and solid internal walls, floors of all levels above DPC and acoustic purposes in walls floors and roofs.
