Thermafleece CosyWool is a low density wool based insulation that is quick and easy to install. It contains 75% Sheep’s wool, 15% recycled polyester and 10% polyester binder with a high recycled content making it highly environmentally friendly. It contains a lofting agent to maintain durability, fibre stability and structural integrity creating a long lasting insulation.

Thermafleece CosyWool comes as a convenient compressed form making it easier to deliver.  Once unpacked, it regains its original thickness to provide effective thermal insulation.  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.  It can reduce CO2 emissions by many tonnes over the lifetime of use.
