High Performance - With a Thermal Conductivity of 0.035 W/mK, Thermafleece UltraWool is the best-performing natural fibre-based insulation on the market. 

Sustainable - Thermafleece UltraWool can reduce CO2 emissions by many tonnes over the lifetime of use.  Wool also fixes carbon dioxide helping reduce greenhouse gas levels.
