WebGlass – Thermal Conductivity. Thermal conductivity of Glass is 1.05 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction. WebThermal conductivity, frequently represented by , is a property that relates the rate of heat loss per unit area of a material to its rate of change of temperature. Essentially, it is a value that accounts for any property of the material that could change the way it conducts heat. In SI units, thermal conductivity is expressed in watts per meter kelvin whereas in …
