    Could you explain to me what the term thermal lag means?

    "Thermal lag describes a body's temperature with respect to time as a result of its thermal mass. A body with a high thermal mass will have a large thermal lag."

    "Thermal lag is the time delay for heat to be conducted through a material. A material with high heat capacity and low conductivity will have a high thermal lag. I hope this helped"

    "Thermal lag measures the time it takes walling materials to lose heat through walls all materials have different thermal lag times I hope this answers your question regards Roy Clarke"

    "A thermal lag (also known as a thermal bridge) is an element of a building partition with a much higher heat conduction coefficient than its neighboring elements. As a result of this feature, the partition is cooled down to a point at the temperature difference inside and outside the building. Thus, an increased, uncontrolled loss of heat occurs through the thermal lag. It is directly proportional to the size of the thermal lag. In the place where the thermal lag/bridge is formed, the temperature of the wall surface often drops to such an extent (at low outside temperatures) that the dew point temperature of water vapor condensation is exceeded. This phenomenon carries a high risk of dampness on the walls of the room and many other negative consequences."

    "Hope this explains this is about as simple as I can make it.

    Thermal lag is the name given to the stored heat being released from the material as the ambient temperature decreases. So thermal mass is a material that stores energy and how long that energy is stored as surrounding temperature change is called thermal lag."
