Thermal insulation is an important technology to reduce energy consumption in buildings by preventing heat gain/loss through the building envelope. Thermal insulation is a construction material with low thermal conductivity, often less than 0.1W/mK.
Heat transfer (or heat) is thermal energy in transit due to a spatial temperature difference. Whenever a temperature difference exists in a medium or between media, heat transfer must occur.

One of the most important and cost-effective energy saving materials in building construction is the insulation. Insulation keeps buildings warm in winter and cool in summer.
Thermal conductivity, often referred to as the 'K' or ' λ' (lambda) value, is a constant for any given material, and is measured in W/mK (watts per kelvin meter). The higher the λ value, the better the thermal conductivity. Good insulators will have as low a value as possible. Steel and concrete have very high thermal conductivity and therefore very low thermal resistance. This makes them poor insulators.
