Thermal Conductivity is the measure of a material’s ability to transmit heat. It is expressed as heat flow in watts per square meter of surface area for a temperature gradient of one Kelvin(K) per meter thickness and is expressed as W/mK. Dense materials have a high thermal conductivity and are inefficient thermal insulates whereas lightweight materials have low conductivity and act as effective thermal insulates. The lower the (K) value of a material, the better is its insulating efficiency.
