It's been my knowledge that many structures are made with insufficient mass insulation. The moment the interior envelope temperature is breached by an exterior temperature differential increased of a lot less than the interior envelope surface area temperature, heat acquire or reduction starts to take place. The rate at which this transfer normally takes area is accelerated with the diploma of differential (i.e. exterior temperatures of 120 degrees vs 32 degrees for warmth gain or decline respectively).
