Frequently Asked Questions

What is Thermal Resistance?

It is a quantifiable measure that describes the ability of a material or system to impede the transfer of heat. It is defined as the temperature difference across a structure when a unit of heat flows through it in unit time. Analogous to electrical resistance, thermal resistance serves as a key parameter in thermal management and engineering, facilitating the analysis of heat flow through materials and devices.

A material or component with high thermal resistance exhibits superior thermal insulation properties, effectively minimizing heat exchange between environments or sections. This concept is important in the design and optimization of thermal insulation for buildings, electronic components, and various heat transfer applications, ensuring efficient energy use and maintaining desired temperature conditions.

How to Calculate Thermal Impedance?

The thermal resistance formula is as follows:

Thermal impedance = (temperature variation) / (heat discharge rate)


  • Thermal impedance represents the impedance to heat flow, typically measured in °C/W or K/W;
  • The temperature variation occurs within a material or system, generally in degrees Celsius (°C) or Kelvin (K);
  • The heat flow rate indicates the rate of thermal transmission through a material or system, usually measured in watts (W).
