How does the thermal performance of Thermafleece compare to other insulation?
Very well: the low thermal conductivity of Thermafleece is comparable to other forms of fibrous insulation and performs within a range of 0.005 W/Mk. Thermafleece is approximately 10% more thermally efficient than glass fibre insulation, which means in a loft you would need a depth of 250mm to comply with current Building Regulations as opposed to 275mm glass fibre compliance.
