THERMAFLEECE Original is a high-density, wool-rich insulation made from the wool of British hill sheep. THERMAFLEECE Original contains 85% wool blended with 15% polyester binder and is certified by the BBA to last the life of the building in which it is installed.
Supplied as 1200mm long slabs in thicknesses up to 100mm that fit securely between rafters, joists and studs, THERMAFLEECE Original provides excellent thermal and acoustic insulation performance.
Like all THERMAFLEECE wool products, it is long-lasting, safe to handle and can contribute to a healthier indoor environment by acting as a moisture buffer and absorbing indoor pollutants such as formaldehyde in the building fabric.
