Lowest thermal conductivity material
Web29 mei 2024 · The insulation is typically expanded polystyrene, and having insulation inside and out gives a U value of at least 0.2W/m2K, with a wall thickness of 250mm. Some systems offer the option to increase the internal insulation and can provide a U value as low as 0.11W/m2K, with a wall thickness of 335mm. U Value = 0.11W/m2K – 0.2W/m2K Web1) The material with the highest thermal conductivity is diamond. Diamond has a thermal conductivity of about 2000 watts per meter-kelvin (W/m*K). This is roughly five times …
