Thermafleece CosyWool - Sheeps Wool Insulation Roll
Rich in British sheep's wool - easy to install between and over joists and ideal for floors and lofts.
Thermafleece CosyWool Roll is a versatile insulation rich in British sheeps wool and is the ideal choice if you are looking for all round performance and value for money. Thermafleece is made from 75% British Wool and 25% recycled polyester. 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, breathability, durability and sustainability.
Thermafleece CosyWool Roll's convenient compressed form reduces transport impacts by more than 50% compared to other natural fibre insulation and makes it ideal for quick and easy installation. Once unpacked, it regains its original thickness to provide excellent thermal and acoustic performance.
Thermafleece CosyWool roll is harmless and can be installed without gloves or protective clothing, although we recommend you wear a dust mask in enclosed spaces such as lofts. Thermafleece CosyWool is not irritating to the skin, eyes or respiratory tract.
To retain the benefits of water vapour, absorption and release, Thermafleece CosyWool roll may be used in conjunction with a vapour permeable underlay. Protect the insulation from prolonged exposure to sunlight when unpacked and avoid wetting for extended periods, store under cover and clear of the ground.

Cutting Tips
Thermafleece can be safely and easliy torn apart, but for a more accurate edge use the 'Roll and Cut' Method
Tools Required: Sharp Scalloped Edge Knife or Insulation Saw
1. For an accurate length. Roll the insulation as tightly as possible along the width. Measure, then taking the insulation saw / knife cut through. This provides a nice, neat edge and is an alternative to tearing by hand.
2. To cut the width of the roll: Keep the insulation rolled and do not unwind. Measure the required width that you need then using the knife or insulation saw begin to cut through the whole roll.
