Thermal Conductivity (Lambda Value) Thermal conductivity, or Lambda value, is the rate at which heat is transmitted through a material, measured in watts per square metre of surface area for a temperature gradient of one Kelvin per metre thickness (W/mK). The lower the value, the better the thermal efficiency of the material. Material Lambda Value […]
