Depending on the facings and thickness, PU can achieve a thermal conductivity as low as 0.022 W/m·K to 0.028 W/m·K. This makes it one of the most efficient insulation materials available on the market. When compared to other materials, a much lower thickness of PU insulation is needed to get the same level of performance.
