- Thermal Lag
Thermal lag describes a material's thermal mass in terms of time. A material with high thermal mass (high heat capacity and low conductivity) will have a high thermal lag. In effect the addition of (or removal of) energy from one side of the mass 'lags' with respect to the other side.
Thermal lag can be a useful feature, as for instance an outer brick wall on the Sunny Sunset side of a house in Winter would radiate its heat into the property in the evening, aiding with heating.
