Hi Ray

If it is a caravan fridge and a built in then it is worth getting the industrial insulation with the reflective sheet attached. I have just insulated around the fridge in the motorhome and it made a great difference to the operation of the fridge

Perhaps worth a bash:
Australasian Insulation Supplies
You may be able to even get some offcuts that size for a 6 pack.

You are usually better off using home insulation pink or yellow batts in the cavity as they fit snugly into the cavity and provide closer contact than foam sheets.
Any hardware store has batts and normally if you have a broken pack they will give you a couple free.

If you can get it use polyurthene sheeting, it's insulation properties is alot better the polystrene, 50mm polyurthene is equal to about 75mm polystrene. As to using pink batts you may as well stuff the cavity with old newspapers for the thermal efficency you will get when it is squashed in to a space (it relies on the air trapped within its fibre to insulate). The only thing to watch when increasing the insulation thickness is moving the thermal balance point (the point within the fridge wall where the outside temperature balances out with the internal fridge) further out to the outside of the fridge and inducing the possibilty of sweating on the outside of the fridge.
