All constructing components perform or radiate warmth, together with mass insulation, based upon resources of radiant heat and air temperatures. It's been my encounter that almost all buildings are designed with insufficient mass insulation. When the inside envelope temperature is breached by an exterior temperature differential higher of less than the interior envelope area temperature, warmth obtain or loss starts to occur. The speed at which this transfer normally takes area is accelerated through the degree of differential (i.e. exterior temperatures of a hundred and twenty degrees vs 32 degrees for warmth acquire or decline respectively).
