Insulation quality inside the fridge construction itself is very important too!!.
Have a look at the consumption ratings for new fridges versus old fridges. ( internet ).
Many old units simply used spray expanding foam about 1 1/2" thick.
Modern fridges use very much more efficient insulation, the name of which escapes me.
