After the interior envelope temperature is breached by an exterior temperature differential better of below the inside envelope area temperature, heat get or decline commences to occur. The rate at which this transfer takes spot is accelerated with the diploma of differential (i.e. exterior temperatures of 120 levels vs 32 levels for heat achieve or reduction respectively).
