Hypothetical Fridge vacuum question?

[Hoohaa]

I have a square SS freezer box in my boat and I have noticed when people design and install a new fridge freezer, they generally have massively thick insulated walls. I was just thinking along the lines of a coffee flask, which has a vacume between the 2 surfaces.

Assuming you could seal it properly, would it be better than say 5 inches of insulation or am I wasting our time.
Also, if someone can give me the correct spelling of vacume? Don't believe the spellchecker.

Best insulator is a vacuum. Maintaining the vacuum however might be difficult.

Many people convert older boxes using vacuum panels and many have found them to be great, some not so great. The main thing is to protect them against punctures and mishandling them during installation. There are many suppliers for the panels, just Google them but here's a link to one example:

It is possible to make a Vacuum fridge freezer, but it most likely would have to be round for the design to be strong enough.

Thanks for the links. Allot of food for thought. I still need to closely examine my current refrigeration to see exactly what its using. Works well but does seem to run most of the time its turned on. So its really using too much power for my liking.
Thanks.
